SLI - Kompatibilitätsbits - Sammelthread

[Longtime Lurker]

I'm glad it could help, I'm working on the unreal engine based Spyro Reignited as well, same exact profile settings as unreal engine 4 apparently likes it, although their are water issues and a very slight Shadow flicker on killing one enemies so far, so maybe under certain conditions it is triggered, maybe alpha effects based but I'm getting 100% scaling on this profile so for anyone interested settings are the same as the Blair witch profile, add profile through NV control panel, shipping exe and any other executable applicable to your version, also as a manual add through profile inspector, is reported at 100% sli on 1070's 8x8 on a GT73VR with the SLI Bits 0x080000F5 with predefined GPU count as four this time but I'm not sure how important this is, and force AFR, same Nvidia version of 436.15 with no standard profile. Hope this helps anyone interested but the game seems well optimised so maybe not as needed as Blair Witch

Update*Further testing shows the profile works well until the flying missions, with vertex explosions upon any contact with water, suspect SSR is the culprit, disabling may help but haven't tested this yet.

[R1fast]

Has anyone had luck with the GR Breakpoint beta in SLI?

I tried the Wildlands official bits and a few custom and while both cards are utilized I only see 5-7 FPS (AFR and AFR2 both do this).

Hello All,

Long time lurker but thought i'd try and help those struggling to achieve anything close to playable on Blair Witch, managed to get what is reported at 100% sli on 1070's 8x8 on a GT73VR with the SLI Bits 0x080000F5 with predefined GPU count as two, and force AFR, also what may help is as of 436.15 there is no profile for the game so adding one via add program on the control panel is the first step. From what i understand these are fairly common sli bits for Unreal Engine, it wasn't perfect by a long shot but it saw me to the end of the game without any noticeable artifacts, flicker ect, misaligned textures and at the end some white lines though considering this game it maybe that these are more just game bugs.

Much respect to everyone putting in the effort on this thread, and this is in no way perfect but hope it can help anyone as impatient as me who wanted to play as soon as possible and bump the FPS.

I am trying to get sli to work on blair witch and tried to follow your instructions, but am still not able to get sli to work. I am quite new to this and it would be great if you could share your nip file for me to try please?

Thanks.

[austinminton]

Managed to fix it, accidentally had 2 profiles for the same exe, causing the problem. Deleting one fixed it.

Hi everyone!

Long time lurker here.

I'm kind of a beginner when it comes to nvlink/sli in games. I have some questions.

1. Nvidia added sli profile for Tekken 7 on driver 382.33. When I start the game with default profile it doesn't utilize mine 2x 2080 ti in SLI. I only get boost on performance when I choose "force AFR2".

2. Is there any "catch" on using "force afr2" on games when it doesn't have a sli profile or custom sli bits provided by the community? I get good performance on some games, but also zero and sometimes very bad performance on certain games.

3. Has anyone attempted to create a working profile for the game Greedfall? I tried to copy the ELEX profile to this game but got zero performance boost. Both game use the same engine.

Hey friend.

1. Nvidia "adds SLI Profiles" to their drivers sometimes that actually just set the bit to force the game to use one GPU. They do this when their internal testing yields no performance benefit or causes unavoidable rendering issues. This is why most of us are here: this thread compiles bits that the community has found to work against the official recommendations of Nvidia. Go to page 1, Tekken 7 is listed in the table.

2. "Force AFR2" enables SLI with no performance enlightenments or compatibility options. Doing this alone will rarely, if ever, be the best option. Additionally, AFR2 doesn't typically matter for DX11 games so you should just use "Force AFR" usually alongside compatibility bits.

3. Yes, I've tested Greedfall on 2x1080Ti with x16/x16 link using driver 436.15, it achieves near-perfect scaling using

SLI Compatibility Bits (DX10 + DX11) 0x080020F1

Also Greedfall isn't using the same engine as ELEX. Greedfall uses the Silk Engine and ELEX uses the Genome engine. Also the ELEX profile is, like the Tekken 7 profile, defaulting to using only 1 GPU.

We have already tested before with a different SLI profile-candidate for Greedfall. Your recommended "0x080020F1" suffer from render-glitches with dynamic render-resolution and depth of field. Could you trying "0x080008F1" instead, if SLI scales fine enough?

Sorry, I searched the thread for Greedfall but didn't find any results yet so I thought I'd share. I haven't noticed any rendering errors caused by dynamic res or DoF with my bits, but your bits also work and achieve similar scaling results. However, both bits result in uneven GPU usage when using dynamic resolution so running the game at any lower resolution than native will more than negate any performance benefits of using SLI.

It's just a suggestion from my side, if you get similar results with SLI, it sounds good. Due to lack of time I can't really test much at the moment, but these bits may be more compatible and don't suffer from the problems mentioned (frame-processing is not in sync as it should!) Also make sure that Dynamic Resolution slider is set to max, only then it is ensured that the monitor's native resolution will be used.

one example at the beginning of the game:

Agree with you about AC Origins and Odyssey but I fired up Wildlands this past weekend and SLI seems to be working great with latest WHQL drivers. I will re-run and post .doc and screenshot.

Interesting, I don't see the shimmering on my setup with 0x080020F1. Could be just differences in driver / GPU architecture perhaps. Thanks for the demonstration though.

I tried both Profiles, both have fine scaling, but with both profiles i get some texture glitching, some kind of blurry textures ^^
i have 1080 ti SLI, with x16/x16 lanes
do i have to change some graphic settings (i have everything maxed out), or is it because of the old sli bridge maybe?

[Omegaferrari]

Hi, have you guys tested Gears 5 in SLI? Does it have support for it like Gears 4?

Thank you for the comprehensive answer!

Do you mind sharing your greedfall profile .nip?

[Blaire]

I'd rather think it's due to different game settings and/or dynamic resolution, but always reproducable here. I am with last 436.30 driver and 2-Way 2080Ti's. AFR-transfers do not behave differently between old and new SLI systems they are all predefined "fixed" functions. Check PM

Hi, have you guys tested Gears 5 in SLI? Does it have support for it like Gears 4?

No explicit DX12 multi-gpu support yet.

Ich hab noch ein anderes Game mit SLI auf Kompatibilität zu prüfen und muss daher GreedFall erstmal nach hinten verschieben. Wenn möglich, schick mir mal ein Save von solch einer Stelle, dann schau ich mal was ich tun kann.

[Arhat1984]

Tested both profiles, scaling is very good but the game runs like dogshit on 7680x4320. I'm astonished I got 60+fps on metro exodus but not on greedfall.

Exclusive fullscreen mode on Borderlands 3 doesn't work when I use SLI, does anyone know why? The screen keeps flashing (black picture) but the sound from the game can still be heard.

When I untick "disable fullscreen optimization" it does work.

[FatRambo82]

Ahh yes, I see that now. Im assuming Wildlands uses a different engine than Breakpoint? If so, that's a shame.

Somebody with luck with Control sli profile?

[Kuzunkhaa]

Hello,
I'm a SLI user for a long time and I learned how to correctly use my SLI system thanks to my experience, trial and error and some very useful posts gathered here and from another forum (a very special thank to @SLIKnight for sharing, but unfortunately has been deleted for some reason and probably not for his/her fault, good info about what is the appropriate SLI-Bits to start for the relative api and tweak it in case: thanks mate! :smile:). Finally I've decided to register here to talk about our SLI systems and share some great SLI-Bits!

So, these days I'm enjoying, when I have time, Pillars of Eternity boosted with OGSSAA using the compatibility bits 0x02500001:

The only problem is the flickering in the game map, but is possible to workaround by open and close it 2 or 3 times the map button or press the "M" key from your keyboard.
If someone find a proper and more "elegant" solution, let us know :)

I've attached two .nip files: one with only the SLI-Bit and another with SLI and OGSSAA (2x2 Supersampling and 4x Transparency Supersampling) enabled.

Is there a proper SLI profile for GRID (2019)?

Is there a proper SLI profile for GRID (2019)?

Presumably there will never be an SLI profile for this because DX12 and Windows 10 are compulsory.

Presumably there will never be an SLI profile for this because DX12 and Windows 10 are compulsory.

There is a DX11 EXE with the game so it can be run in DX11 which means SLI should technically be possible.

Chernobylite is nice new game on UE4 in early access. I've bought version from GOG.com and tried Noiseovore profile for Remnants: From the Ashes. It works without bugs, it has decent scalling and all I had to do is set Post Effects settings to low. Everything else can be at Ultra, including shadows. I enclose edited profile and screenshots.

0x000000F1 works fine, put all on ultra and set Shadows on High not Ultra to avoid GTX SLI Bandwith Limits
on 1440p , you can reduced the Antialiasing, TAA is to blurry , try it at Low thats really correct!
Look performances during benchmark or in game: Benchmarks Results are wrong
We will post a different Solution for this game.
Dont use the SLI broadcast used on Remnant

With the 3.8GB of VRAM of Your GTX 970 , the game cant load the Ultra Presets , reduced them

[Meph]

Thanks for the response and insight! I was definitely not going to use ultra on 970, exactly due to memory issue :). I was just checking at which setting the load on SLI cards is going down. BTW: the developers consider providing official SLI support in the future.

[Gast]

Where to get the Profile ? folder ? for Chernobylite

[Gast]

Look for information on Nvidia Profile Inspector - there is a lot of sites describing how to.

Yeah! Sorry but with this game i have seen only that is impossible without flickering

[jan90]

Hey,

ich würde gern bei Outer Worlds SLI Profile testen, allerdings übernimmt das Spiel die Einstellungen aus den Nvidia Profile Manager nicht, nicht einmal beide GPUs werden genutzt...
Die Lösung, die bei BF5 halt, hilft hier auch nicht weiter. (Also die beiden Dateien im Nvidia Corporation Ordner auf Ready Only zu setzen)
Nur wenn ich direkt über die Nvidia Systemsteuerung auf Afr/Afr2 setze, bekomm ich beide karten zum laufen, aber dann natürlich mit keinem Scaling, da das Nvidia Profil ja nicht genutzt wird.
Jemand ne Idee, woran das liegen könnte?
Hab die Version aus dem Windows Store, bzw Xbox App

Ist normal, das offizielle SLI Profile funktioniert nur in Verbindung Turing-GPU's und NVLink-Interface, mit Pascal SLI (oder älter) bleibt es beim SingleGPU-Modus. Müsstest also die SLI Compatibility Bits auf "0x080000F1" für 2-Way AFR ändern. (Original "0x080000F4")

[SLIKnight]

Trust me, there is no proper SLI solution for Batman: Arkham Knight without serious problems.
I have tested every possible combination of undefined bits before including the "Impossible without severe flickering" comment in my master thread spreadsheet.

Ich habe die sli bits von witcher 3 versucht, da die auch bei hellblade senuas satrifice funktioniert hatten, diese sind ja ebenfalls nicht Turing exklusiv und sollten mit Pascal funktionieren

Dann wird sich wohl die Executable der Windows-Store Retail-Version zum vorgefertigten Application-Profile im aktuellen NVIDIA Treiber unterscheiden, wäre das naheliegendste und ließe sich recht einfach herausfinden.

[jan90]

Das hatte ich auch vermutet, nur leider lässt sich die exe nicht dem NVIDIA Profile Manager hinzufügen, da ich da keine rechte für habe, obwohl ich admin bin. Den installationsordner kann ich leider auch nicht in Besitz nehmen,scheint ein Windows xbox app Bug zu sein, zumindest bei dem Spiel, andere xbox app games kann ich in besitz nehmen, um mir die rechte zu geben.
Dann warte ich ab, bis das gefixt wurde.

Danke für die Infos und schönes Wochenende!

Anyone have any luck with the outer world's? Downloading now to take a stab at it. Turing SLI is supported, but not older hardware. I am going to try what is working with other UE4 games in this thread. I'll post back if I have any luck. Just wanted to see if anyone else is working on it as well.

Sorry, I suppose I was not specific. The official profile only supports Turing cards. I am attempting to force it with older cards. Specifically I am on 2 1080ti's.

Ok here is what I managed on my own.

As others have guessed, the Turing only SLI is because of PCIe bandwidth limitations. I'm on x8/x8 and I have hit the wall. Here is what works for me.

SLI Broadcast: 0x0000008
SLI Comparability Bits: 0x080000F5
Number of GPUs: FOUR
SLI Mode: FORCE_AFR

Using this Engine.ini to fix some defaults https://www.nexusmods.com/theouterworlds/mods/9

Edit above ini to force shut off TAA

This will scale. At 1600p I get usage at 85 to 95 and over 100fps ultra with 2 1080ti's. The issue is at 4k. Utilization drops to 70ish and fps is about the same as a single card. That being said, 4k SLI IS more stable sitting at a solid 45 fps vs jumping from 50 to 40 every second (while stationary). This is happening because I am hitting my bandwidth wall I think. I can't push anything more through the lanes to boost the performance.

However, for folks who have older cards who want SLI at 1080 or 1440, this should work great for you!!

Thank you to u/tuxubuntu for the advice here https://www.reddit.com/r/nvidia/comments/c98mjj/is_there_an_updated_list_of_sli_optimized_games/esvinb0?utm_medium=android_app&utm_source=share

Edit: Based on this thread https://www.reddit.com/r/pcgaming/comments/8zbr2i/guide_proper_custom_resolution_upscaling_to_4k/?utm_medium=android_app&utm_source=share, I created a few custom resolutions to see how much I could push it while getting at least 80% scaling on average. 1800p is very close and sits at 57 to 63 fps with 78 to 85% scaling.

Dropping down one more to 80% of 4k (damn...a lot of 80s. Lol) gets me a solid 60 to 68 fps with 85% scaling. Dropping to 1600p gets 95% scaling and 80 to 90 fps.

The default profile in 440.97 even with Turing cards supports only one GPU.

Has anyone had luck getting SLI to work (with the supported Turing cards) on The Outer Worlds from the Windows Store? It seems to be working on the Epic version based on other reports but I can't get it to work on the Windows Store app.

[Gambinesh]

great profile :)
with taa deactived, i have on 4k everything set on ultra about 65-70fps, instead of 40-50fps.
im on 1080 ti sli, but x16/x16 (both cards 100% usage)

Well that confirms my bandwidth guesses. I'm sticking with 1 card because I get 60s by itself. Btw, updated the post a bit. SLI hacks wasn't actually doing anything so I removed it. Also, the broadcasting bits changed to 08 gives better utilization.

I'm using 2 gpus with Windows Store version, default profile can't find the game basically, however you can still add it via nvidia control panel. In Nvidia control panel add game to your 3d settings in program settings, it should show up in the list. After force alternate frame rendering 1 and it should work. I'm not sure if it creates a separate profile in nvidia inspector when you add the windows version, haven't looked into it to make better changes.

No! it does not work...(it show as it run in SLi but the performance as one card)

So base as your guide, I do the same way(but add it as nvidia official SLI bits) and make this profile...for easy to use.

Note: this profile is using the same Nvidia officical Sli bits, so it only adds support for Windows Store version and RTX cards only.

This is working perfectly for me... Thank you!

Ok here is what I managed on my own.

As others have guessed, the Turing only SLI is because of PCIe bandwidth limitations. I'm on x8/x8 and I have hit the wall. Here is what works for me.

SLI Broadcast: 0x0000008
SLI Comparability Bits: 0x080000F5
Number of GPUs: FOUR
SLI Mode: FORCE_AFR

Using this Engine.ini to fix some defaults https://www.nexusmods.com/theouterworlds/mods/9

Edit above ini to force shut off TAA

This will scale. At 1600p I get usage at 85 to 95 and over 100fps ultra with 2 1080ti's. The issue is at 4k. Utilization drops to 70ish and fps is about the same as a single card. That being said, 4k SLI IS more stable sitting at a solid 45 fps vs jumping from 50 to 40 every second (while stationary). This is happening because I am hitting my bandwidth wall I think. I can't push anything more through the lanes to boost the performance.

However, for folks who have older cards who want SLI at 1080 or 1440, this should work great for you!!

Thank you to u/tuxubuntu for the advice here https://www.reddit.com/r/nvidia/comments/c98mjj/is_there_an_updated_list_of_sli_optimized_games/esvinb0?utm_medium=android_app&utm_source=share

Edit: Based on this thread https://www.reddit.com/r/pcgaming/comments/8zbr2i/guide_proper_custom_resolution_upscaling_to_4k/?utm_medium=android_app&utm_source=share, I created a few custom resolutions to see how much I could push it while getting at least 80% scaling on average. 1800p is very close and sits at 57 to 63 fps with 78 to 85% scaling.

Dropping down one more to 80% of 4k (damn...a lot of 80s. Lol) gets me a solid 60 to 68 fps with 85% scaling. Dropping to 1600p gets 95% scaling and 80 to 90 fps.

I've built the following nip file based on this but the perf in 4k are awful (10fps less than on a single card), probably missed something.(i'have two 1080)

if someone has an idea? thx

[SandroX]

Hey guys, I know it's early given todays launch but any word on a SLI profile for Red Dead Redemption 2?

According to NVIDIAs own graphics/performance guide, even a 2080 Ti can't handle 4k/60fps (only with a mixture of Med/High settings). Ultra is out of the question.

My hope is that my two Titan Xps could handle it as long as it scales as well as GTA V.

[Sn4rFx]

So red dead redemption 2 launched and there is no sli profile, i forced the GTAV profile and it worked with Vulkan, Dx12 dont work, it scales well on vulkan, both cards at 99%, but i got some flikering in rocks and trees, if anyone here have the knowledge pls make one.

Hello, Red Dead Redemption profile for Pascal cards GTX 1080s SLI

Has nothing to do with GTA V. :) Red Dead Redemption II has MultiGPU integration from the game-developer, so the NVIDIA driver prevents this with a driver-flag, and if you use a different application-profile, MultiGPU mode is detected and active. But unfortunately with too many issues, so its not really usable.

[1415gateway]

So red dead redemption 2 has GPU support?

[1415gateway]

I don't think you quite understand what I was saying on YouTube someone using two 970s in SLI and he used the Grand Theft Auto V profile first deleting Red Dead Redemption 2 profile, he got it working.
But then I read that 1080s doesn't work so is there SLI support for Pascal cards?

Read carefully what I have wrote. Red Dead Redemption II obviously have "built-in" Vulkan MultiGPU support by the game developer, that's the only reason. It has nothing to do with a GTA V profile or something like. The 441.12 driver just disallow MultiGPU-support for Red Dead Redemption II app-profile in current driver, because it doesn't work properly! Thats it.

Yes, it's right. The developers probably need time to patch this feature and probably are also developing it in the dx12 version. Maybe, with a future update, it will be activated. I found a profile that allows the use of multigpu and I tested it for a long time. There is a 100% gain (like GTA V), but there are flickering. Using TAA and vertical synchronization, flickering are reduced, but remains in snowy landscapes (in the benchmark they are much more marked than in chapter 1).
Yes, i'm back:smile:

[Skinner.]

Hehehe, the GTA 5 profile works. Not very usable in snowy area's in the beginning of the story mode due to much flickering and lower scaling (due snow particles?), but the start in online mode it works better, from 30-35 single GPU to ~50-55 fps @ 5K Ultra and 98-99% load on both GPU's (2080Ti's) and no flickering. But not so smooth in some parts, but this give me some hope for the future.

No, it's not me. I tried another solution. The result is always the same: the snowy areas (in particular) have a lot of flickering.

Read may post again. This appears to be a bandwidth issue. There are some bits that get better performance at 4k, but it breaks the sky. I am tracking my tinkering here and will post back at 3DCenter if I get something that is actually useful. For now, this is early WIP and may not go anywhere. https://www.reddit.com/r/theouterworlds/comments/do3llb/sli_for_anyone_interested/?utm_medium=android_app&utm_source=share

[Noiseovore]

Really All of that becomes fantasy!

Using Broadcast when thats really useless!
The Outers Lands works well with F5 without any Broadcast, just find the goob bits when The bandwidth is not limited.

And Activating MGPU with a random game profile! Using DX11 Bits on a Vulkan game
change this value : 0x20247E01 = 0x0000000 When Nvidia Set it to 0x0000002 to disabled the MGPU.

I am not sure I follow all of this. I did realize that broadcast wasn't doing anything really. I am updating my post on Reddit regularly so my post here is a bit old. I also found that the hacks aren't doing anything either. Really only bits are affecting things.

I don't follow what you are saying about vulkan. Can you elaborate? The issue is that I get utilization with no performance increase (a decrease actually) with most bits and when I do find bits that increase performance (like 0x080222F) I get issues rendering the sky. The sky rendering issue can be seen here https://ibb.co/2ZXgj2P.

Either I find better bits or find what is causing the sky rendering issue and try to disable it. That's the only path forward that I can see.

[Noiseovore]

0x20247E01 = 0x0000001 MGPU enabled.

for any flickering or visuals bugs wait Game update with Mgpu support by game Devs

look the RDR2 profil on 440.97 drivers

...from 30-35 single GPU to ~50-55 fps @ 5K Ultra...

That's okay for a start. Interesting that this might help in future running nice settings at low level API games - well, maybe not in every title but in some. :D

You can use GFE Filters [ALT+F3] though for RDR2 @ Vulkan - I did not test these yet (on my main machine I am running RDR2) - only NV sharpen + ignore filmgrain combined with T.AA medium -> that's the best result for my setup as without it looks kind of blurry.
Just download a ReShade filter pack and extract it into you're Ansel folder. But I have to mention that after switching the filters too much and quickly, I could not start games like The Division 2 any more, so I had to delete GFE (tested it on the second system) - that does need some time to work perfectly, I suppose. :)

The NVIDIA ReShade Filter Collection

To help get you started, NVIDIA is providing a collection of curated ReShade filters (https://international-gfe.download.nvidia.com/GFE/GFEClient/ReShadeFilters/v1.0/Curated_ReShade_Filters.zip), which includes two new filters they created with ReShade filter author Pascal Gilcher:

Posterize : Adds a pop-art effect, and reduces the image to 4 colours
Retro Neon : Uses the game’s depth to create a cool sci-fi effect




Example picture with 40% sharpen and 15% ignore filmgrain:
https://abload.de/img/rdr2_2019_11_08_14_48vakkq.png Yes, a bit of grain, but for me that's way better then losing sharpness and with it a lot of small texture details are missing. :)

[Suzerain]

Since RTSS does not work well with Vulkan MGPU (massive flickering) and there is no fix in sight, is there another program we can use to monitor hardware stats in-game using Vulkan MGPU?

Also, is there a way to edit the Nvidia ShadowPlay OSD (FPS display, size, location, color etc.)?

Questions about the future of mobile sli:
1. Is sli forever dead in laptops?
2.Will it ever be possible to implement nvlink on a laptop?
3.My 2017 gt83 with dual 1080s still beats any laptop from 2019 with a 2080 on any game supporting sli even a 2080 ti. So are we now only going to get lover proformance gaming laptops with the same price?
4.Why is direct x 12 working against sli?
5. Will AMD release gaming laptops to compete with Nvidia and will they support cross fire?

[Skinner.]

Do somebody have Rune 2 (UE4-engine)? I'm trying to get SLI working, but I haven't found any with decent scaling and no flickering.

Tried, The Witcher3, Hitman2 and "Shootergame" gameprofiles, but neither scales well and all need broadcast bits (0xxx1) to get rid of the flickering.

Maybe I have to lower T(AA) but it looks so good with it on (offcourse corrected with reshade;))

Für alle "leidgeplagten" SLI-User eine erfreuliche Nachricht,
NVIDIA haben relativ unbemerkt ;) einen neuen SLI-(MultiGPU)-Render-Modus im NVIDIA Treiber (erstmals ab r435 Treiber-Branch) integriert, welcher sich "CFR"-Modus nennt, was genau dahinter steckt bzw. die genaue Funktionsweise ist aktuell (noch) unklar. Ich hab den neuen Render-Modus eher zufällig vor knapp 2 Wochen entdeckt und da dieser in offiziellen NVIDIA Treiber'n abrufbar ist, wollte ich dies Interessierten nicht vorenthalten!
Anhand meiner Tests handelt es sich offenbar um eine auf Checkerboard-Rendering-basierende MultiGPU-Render Methode, welche effizientere Daten-/Speicherzugriffe (P2P) zwischen zwei geeigneten NVIDIA "Turing"-Grafikkarten mit NVLink-Interface erlaubt, mit der Besonderheit das dieser auch mit DirectX-12 Games/Anwendungen zurecht kommt! Und genau das macht es so interessant! Der neue Modus ersetzt offenbar den alten Split-Frame-Rendering Modus (als auch über die gleiche Setting ID aktivierbar!) welcher jedoch schon längere Zeit nicht mehr offiziell über NVIDIA Treiber Control Panel anwählbar war, der neue CFR-Modus funktioniert hingegen für alle aktuellen DirectX-API's, ab DX10 aufwärts!
NVIDIA hatten damals zum Turing-Launch angekündigt, das NVLink ein Langzeit-Investment sei um die GPU's "closer" zu schalten bzw. wie diese untereinander kommunizieren.

Um den neuen Modus zu aktivieren, genügt es den alten SFR-Rendering Modus im gewünschten Game-/Application-Profil z.b. geeigneten third-party-Tool wie dem Nvidia-Profile-Inspector zu aktivieren.

SLI_RENDERING_MODE_FORCE_SFR aka "Setting ID_0x1033ced1 = 0x00000004"

Achtung: Bei bereits existierenden bzw. vorgefertigten SLI-Profilen kann es sein, daß man auch die jeweiligen SLI Compatibility Bits ändern muss, es ist dabei entscheidend daß der 8-stellige Hexadezimalcode mit einer "2" endet, siehe Screenshot.


Erste Tests bescheinigen, daß der neue SLI-Modus durchaus seine Vorteile gegenüber AFR hat, so funktioniert ein "Metro Exodus" unter DirectX 12 inkl. Raytracing Global Illumination einwandfrei, dies war zuvor mit AFR nicht machbar, die starken Frame-Abhängigkeiten moderner Workloads dies nicht mehr zuließen. Ich hab den Story-Modus komplett neu durchgespielt und konnte keine Probleme mit zwei RTX 2080Ti während dessen feststellen.
Ob dieser neue SLI Algorithmus zwingend eine NVLink-Verbindung voraussetzt oder auch mit älteren SLI (zumindest theoretisch) funktioniert, ist unbekannt, da einfach keine offiziellen Informationen vorliegen.
Allerdings gibt es noch reichlich Kompatibilitäts-Probleme, einige Games starten erst garnicht oder Probleme grafischer Art treten auf, dies sollte dabei nicht unerwähnt bleiben! Der Modus scheint also noch experimentell, was ich ganz sicher sagen kann, das der CFR-Modus keinen AFR-Ansatz mehr verfolgt, weniger Latenz verursacht und dies nicht nur spürbar, sondern auch messbar ist!
Zwischen 30-60% Leistungszuwachs sind nach meinen ersten Game-Tests durchaus realistisch, das ist nicht so effizient wie mit AFR aber dennoch nicht schlecht.

Eine kleine Auswahl an Games , welche ich bislang, "mehr oder weniger" hin auf Kompatibilität überprüfen konnte.
Mehr war in der Kürze der Zeit einfach nicht machbar. Auf einzelne Benchmarks musste ich verzichten, aber grob zwischen 30-60% Leistungszuwachs sind durchaus realistisch , je nach Game, Auflösung und Settings natürlich. :)

Kurzes Gameplay-Video aus Metro Exodus (DX12) sowie dem "Neon Noir"-RayTracing Benchmark von gestern, wo der CFR-Mode problemlos funktioniert.
PBO1jDM3atAv7_wsdoUaO8

Die Kompatibilität in Games lässt wie bereits erwähnt noch etwas zu wünschen übrig, dennoch gibt es auch genug Games welche funktionieren und im Vergleich zum Alternate-Frame-Rendering auch besser abschneiden.
Man wird sehen, wohin die Reise geht, wie sich SLI(MultiGPU) in Zukunft weiter entwickeln wird. Diese Methode ist jedoch ein erster wichtiger Schritt, um SLI wieder etwas "Leben" einzuhauchen, wieder mehr Optionen zu erhalten. So sollte man das auch betrachten...

Update (26.11.)
Ich war die letzten Tage nicht untätig und konnte mir einen besseren Überblick verschaffen, ich werde demnächst auch die Game-Kompatibilitätsliste mit dem neuen CFR-Modus noch etwas erweitern, es ist halt sehr zeitraubend aber auch spannend zugleich!
Der neue CFR-Modus liefert auch einige überraschende Dinge zu Tage, so fiel mir auf, das in vielen Game-Titeln die Minimum-Framerate im CPU-Limit generell etwas besser ausfällt, als es mit AFR-SLI noch der Fall war, es dürfte sich wohl um geringeren Verwaltungsaufwand (Overhead) für den Grafiktreiber handeln, auch die Kompatibilität mit verschiedenen Anti-Aliasing Modis hat sich verbessert, so u.a. in Deus Ex Mankind Divided dort war Temporal AA stets kaputt, egal ob DX11-(SLI) oder DX12 (mGPU)-variante, nun mit CFR funktioniert TAA genauso gut, wie mit einer einzelnen Grafikkarte. Auch waren verschiedene Anti-Aliasing-Modes in Games mit AFR-SLI nicht verfügbar oder wurden ausgeblendet, mit CFR gibt es diese Einschränkungen nicht mehr.
Die Kompatibilität scheint in DX11 Games insgesamt auch etwas besser zu sein , unter DX12 jedoch noch stark verbesserungswürdig.
Ich hoffe NVIDIA stecken da noch einiges an Treiber-Optimierung rein. Ich bin jedenfalls sehr angetan und positiv überrascht, ob der neuen Möglichkeiten die sich nun eröffnen!

Update (15.01.2020) Leider sollte es wohl nur bei einem kurzen "Gastauftritt" bleiben, mit Beginn der nächsten NVIDIA-Treiberserie ist kein SLI-CFR Modus mehr aktivierbar...
Eine erste Game-Kompatibilitätsliste mit dem neuen SLI-CFR Modus findet sich unter folgendem Link: https://www.forum-3dcenter.org/vbulletin/showpost.php?p=8881192&postcount=43

Wow, thanks for the discovery, gonna with it right away :)

[jan90]

Schöne Neuigkeiten! :)
Scheint aber nicht mit den alten GPUs zu funktioneren, habe ja 2x 1080 ti mit je 16 lanes.
Kurz getestet mit
Metro Exodus Dx11 schlechtere Fps wie mit Single, Dx12 Absturz
A Plague Tale Dx11 etwa diesselben Fps wie mit Sinlge
Hunt Showdown Dx11 schlechtere Fpsj
Divison 2 muss grad noch ein Update laden, aber ich vermute, dass sich das nicht anders verhält.
Edit: Divison 2 Dx11 und Dx12 hat auch schlechtere Fps, sowie Texture Flickern
Alle Spiele waren auf 2160p, außer Hunt Showdown, dort waren es 1440p

Beide Grafikkarten waren immer auf knapp 100% Last, also an sich funtioniert das. Vermutlich werden die Daten zwischen den Grafikkarten nicht schnell genug übertragen? Da der PCI-E Bus immer nur zu etwa 25% belegt war, werden die Daten wohl über die GPU Bridge verteilt, die bei Pascal einfach langsamer ist, als bei Turing :)

SLI_RENDERING_MODE_FORCE_SFR aka "Setting ID_0x1033ced1 = 0x00000004"

Erste Tests bescheinigen, daß der neue SLI-Modus durchaus seine Vorteile gegenüber AFR hat, so funktioniert ein "Metro Exodus" unter DirectX 12 inkl. Raytracing Global Illumination einwandfrei, dies war zuvor mit AFR nicht machbar, die starken Frame-Abhängigkeiten moderner Workloads dies nicht mehr zuließen. Ich hab den Story-Modus komplett neu durchgespielt und konnte keine Probleme mit zwei RTX 2080Ti während dessen feststellen.
Ob dieser neue SLI Algorithmus zwingend eine NVLink-Verbindung voraussetzt oder auch mit älteren SLI (zumindest theoretisch) funktioniert, ist unbekannt, da einfach keine offiziellen Informationen vorliegen.
Allerdings gibt es noch reichlich Kompatibilitäts-Probleme, einige Games starten erst garnicht oder Probleme grafischer Art treten auf, dies sollte dabei nicht unerwähnt bleiben! Der Modus scheint also noch experimentell, was ich ganz sicher sagen kann, das der CFR-Modus keinen AFR-Ansatz mehr verfolgt, weniger Latenz verursacht und dies nicht nur spürbar, sondern auch messbar ist!
Zwischen 30-60% Leistungszuwachs sind nach meinen ersten Game-Tests durchaus realistisch, das ist nicht so effizient wie mit AFR aber dennoch nicht schlecht.

Eine kleine Auswahl an Games , welche ich bislang, "mehr oder weniger" hin auf Kompatibilität überprüfen konnte.
Mehr war in der Kürze der Zeit einfach nicht machbar. Auf einzelne Benchmarks musste ich verzichten, aber grob zwischen 30-60% Leistungszuwachs sind durchaus realistisch , je nach Game, Auflösung und Settings natürlich. :)

Kurzes Gameplay-Video aus Metro Exodus (DX12) sowie dem "Neon Noir"-RayTracing Benchmark von gestern, wo der CFR-Mode problemlos funktioniert.
https://youtu.be/PBO1jDM3atAhttps://youtu.be/v7_wsdoUaO8

Die Kompatibilität in Games lässt wie bereits erwähnt noch etwas zu wünschen übrig, dennoch gibt es auch genug Games welche funktionieren und im Vergleich zum Alternate-Frame-Rendering auch besser abschneiden.
Man wird sehen, wohin die Reise geht, wie sich SLI(MultiGPU) in Zukunft weiter entwickeln wird. Diese Methode ist jedoch ein erster wichtiger Schritt, um SLI wieder etwas "Leben" einzuhauchen, wieder mehr Optionen zu erhalten. So sollte man das auch betrachten...

[Skinner.]

The Evil Within 2, Batman Arkham Knight!!! ( and GOW5 (some flickering), are working too :) This is awesome. To bad COD MW RTX refuse to run (yet?)

[Meph]

Looking forward to SLI-CFR on non-NVlink cards ;).

[Suzerain]

@Blaire

This is amazing!

For Metro Exodus (DX12), do we have to reset our profile to default and remove the modded EXE (we had to do that to get SLI to run in DX11 before)?

Also, what about the following games:

Assassin's Creed: Origins - scales both GPUs but performance is worse than single GPU
Assassin's Creed: Odyssey - scales both GPUs but performance is worse than single GPU

For Vulkan API - what about MGPU for the following games:

1.) RAGE 2
2.) Wolfenstein - The New Colossus
3.) Wolfenstein - Youngblood

Setting the 'Strange Brigade' bits in the 'Unknown' section does not enable MGPU.

[Blaire]

Schöne Neuigkeiten! :)
Scheint aber nicht mit den alten GPUs zu funktioneren, habe ja 2x 1080 ti mit je 16 lanes.
Kurz getestet mit
Metro Exodus Dx11 schlechtere Fps wie mit Single, Dx12 Absturz
A Plague Tale Dx11 etwa diesselben Fps wie mit Sinlge
Hunt Showdown Dx11 schlechtere Fpsj
Divison 2 muss grad noch ein Update laden, aber ich vermute, dass sich das nicht anders verhält.
Edit: Divison 2 Dx11 und Dx12 hat auch schlechtere Fps, sowie Texture Flickern
Alle Spiele waren auf 2160p, außer Hunt Showdown, dort waren es 1440p

Beide Grafikkarten waren immer auf knapp 100% Last, also an sich funtioniert das. Vermutlich werden die Daten zwischen den Grafikkarten nicht schnell genug übertragen? Da der PCI-E Bus immer nur zu etwa 25% belegt war, werden die Daten wohl über die GPU Bridge verteilt, die bei Pascal einfach langsamer ist, als bei Turing :)

Sehr interessant. Aber konnte man bereits vermuten, im offiziellen NVIDIA Turing Whitepaper wurde auch nur NVLink im Zusammenhang mit neuen Modis genannt. Wird denn "SLI-CFR" auch im Overlay angezeigt?
Das tolle an dem Modus ist halt, das beide GPUs am selben Frame rendern (die jeweils zugewiesenen geraden/ungeraden Bildrechtecke)
Pre-rendered Frames wie bsplw. mit AFR sind somit auch hinfällig, was der Latenz zu gute kommt. Selbst wenn der Leistungszuwachs nicht allzu üppig ausfallen sollte, kann das allgemeine Smoothness-Gefühl trotzdem optimal sein.

[jan90]

Hey,

ja der SLI-CFR Indicator wird angezeigt.
Ja die Technik ist schon interessant, echt schade, dass das mit Pascal scheinbar nicht funktioniert.
Beim neuen Benchmark von Crytek funtioniert das auch nicht, 4k Ultra Settings mit CFR knapp 2000Punkte, mit Single 2600 Punkte.

Oder muss noch was anderes eingestellt werden, abgesehen von Force SFR (und, wenn man möchte den SLI Indicator)?

So the gtx 10 series is not compatible with SLI-CFR? Also their is a new latency mode that may give better performance.

No surprise with The Surge 2, CFR is not supported for Vulkan, only DirectX-10/11/12 - API's for now. Terminator Resistance it seems to work here (but tested only for a short time). Make sure also CFR is really engaged.

The settings was wrong, my apologies for misinformation. Now after having correct settings I can confirm now that CFR works in Terminator Resistance.

New game I tested:
Shenmue 3 (Unreal Engine 4, DX11)

Played only for 1 hour and CFR works fine without any flickering or graphical glitches. Max settings (Very High) with 7680x4320 getting average 35-40 fps.

When I switch to AFR I get better results average 42-50 fps.

I'm still very happy with CFR despite lower fps gain compared to AFR.

It looks like, an updated game-compatibility-list with profiles and additional notes could certainly be helpful, as long as there is no official CFR-support in the driver.

Bei dem Youtube-Video ging es mir nicht um das Ergebnis, das war mit aktiven G-Sync 3840x2160 "60 FPS-Lock" bei 60Hz aufgenommen, zudem kostet die Aufnahme mit Shadowplay auch einiges an Leistung. Die Punkte haben daher nicht wirklich Aussagekraft.

[Leonidas]

Ahhh, okay. Ich hoffe einfach, das andere Ergebnisse höhere Skalierungen ergeben. Da lag früher mal der Pferdefuß von SFR - die Skalierung war zumeist nicht hoch.

[Geldmann3]

Es scheint als sei dieser Modus extrem von der Bandbreite zwischen den GPUs abhängig. Mit der nächsten Generation unter PCIe 4.0 oder mit zwei Chips auf einem Board könnten die Performancezuwächse deutlich besser sein. Allerdings ist die Kompatibilität jetzt ernüchternder Weise auch nicht um Welten besser als AFR. Wäre episch, wenn das mit jedem Game funktionieren würde, ich würde mir dauerhaft eine zweite 2080 Ti verbauen.

[Blaire]

Ich hab jetzt noch 3 ausgewählte Game-Benchmarks hinzugefügt.

1.) "Crysis 3" was bereits einige Jahre auf dem Buckel hat (erschien 2013), galt aber schon immer als optimal für SLI (AFR) optimiert und ist auch heutzutage noch sehr hardwarehungrig, speziell unter 3840x2160 Auflösung, maximalen Grafiksettings und 4xTXAA!
Als Benchmark wurde die fordernde Map Swamp "Ingame-Engine-Sequenz"(111 Sekunden) verwendet, siehe auch das verlinkte Video.
https://youtu.be/67Nzs17EPnY
https://abload.de/img/crysis3-comparison8ekew.png

2.) "Chernobylite" (basiert auf der Unreal Engine 4) und erschien Oktober im Steam-Early-Access, dafür gibt es weder offizielle SLI-Unterstützung, jedoch kommt dieses Game auch mit einfachem AFR2 Render-Modus zurecht, so daß sich das ebenfalls zum Vergleich mit CFR anbot. Als Benchmark kam der game-interne Benchmarktest zum Einsatz, siehe Beispiel-Video:
https://youtu.be/YBKOI7LZYrE
https://abload.de/img/chernobylite-comparisyvk8r.png

3.) "A Plague Tale: Innocence"? Da es für diese Game weder offizielle SLI-Unterstützung, noch ein inoffizielle custom SLI Profile Lösung gab. Es war quasi unmöglich, dieses Game mit AFR zur Zusammenarbeit zu bewegen, erst recht nicht inklusive Temporal AA.
Als Benchmarkszene hab ich jene von PCGH verwendet, siehe Links. Die Werte sollen ja auch für jedermann nachvollziehbar bleiben, daher fiel die Wahl darauf.

https://www.pcgameshardware.de/A-Plague-Tale-Innocence-Spiel-60687/Videos/Benchmark-Sequence-Video-FAQ-1289030/
Alle Benchmarks wurden mehrfach wiederholt, für bestmögliche Vergleichbarkeit, die jeweiligen Minimum-Framerates entsprechen 1% Low FPS-Werten ermittelt mit OCAT.

Ahhh, okay. Ich hoffe einfach, das andere Ergebnisse höhere Skalierungen ergeben. Da lag früher mal der Pferdefuß von SFR - die Skalierung war zumeist nicht hoch.

Ist unterschiedlich, 30-60% (grob geschätzt) je nach Game, Auflösung und Grafiksettings.

It is really surprising that CFR performs much WORSE than AFR in this game. I sit because it's an older game and AFR is implemented quite well?

RE2 Remake is a good example of how well CFR works. With profile hacks and getting AFR to work, there is always some light flicker and microstutter. With CFR, it's very very smooth and gameplay is incredible.

I guess we need to compile a table of games that work very well with CFR etc.

[Blaire]

Super! Was macht der Neon Noir mit AFR unter derselben Hardware?

Mit normalen AFR leicht negative Performance, mit AFR2 Modus in etwa gleich (minimal flotter). Über die üblichen SLI compatibility flags mit zusätzlichen AFR-transfers-skips könnte man sicher noch ein wenig mehr Leistung herausholen. Aber AFR/AFR2 sind die offiziellen Rendermodis, welche auch der NVIDIA Treiber anbietet und darauf wolltest du sicher hinaus?
Ich hätte gern noch die Frameverläufe gepostet , aber aus irgendeinem Grund verschlechtern sich die Werte mit OCAT in diesen Benchmark mit CFR, das muss ich mir später nochmal ansehen.

Was die Bewertung von SLI allgemein betrifft, steckt auch viel Vorurteil dahinter. Du musst auch bedenken, das die Test-Redaktionen immer nur begrenzte Möglichkeiten haben, meist nur ihren Parcour durchtesten oder stichprobenartig Beispiele zeigen und das wars. Es spielen da soviele Faktoren mit rein, welche für Microstutter & Co sorgen können, gerade unter Windows 10, borderless Fullscreen/Vollbildoptimierungen + verschiedene DWM-Hacks, G-Sync das es eigentlich absurd ist, SLI nach nur wenigen Tagen bewerten zu wollen. Da geb ich generell nichts drauf. Wenn SLI/MultiGPU ordentlich vorbereitet und unterstützt, dann lohnt sich das auch! Nur war das zuletzt immer seltener der Fall und da hoffe ich nun auch, dass der CFR Modus ein erster Schritt ist, mehr in dieser Richtung zu tun.

It works on 10 series cards. I'm using a modified profile for Escape from Tarkov. Raised my minimum FPS but dropped my Max and in that game, I'm willing to live with that. FPS stays locked at 49 FPS @ 5120 X 1440

Game does not run perfectly but issues do not get in the way of gameplay. Evidence of this working is artifacts of checkerboard rendering in some menus. Can try and get screenshots of people are interested.

Another SLI update for Dead by Daylight

Updated SLI post
3DCenter SLI thread (#2913) (https://www.forum-3dcenter.org/vbulletin/showpost.php?p=11778542&postcount=2913)

Did some further digging around in the latest version of Dead by Daylight.
It seems the only real SLI solution now is to use 0x080040F1 combined with setting 0x00A06746 to 0x00010100.
This gives at least some consistent scaling, and every other custom profile causes one problem or the other.

Crash Bandicoot™ N. Sane Trilogy

Hello, is a pleasure to share the SLI profile for our loved Bandicoot!
First of all I highly suggest to unlock the refresh rate by using a tool like 3Dmigoto (direct link to version 1.3.16) (https://github.com/bo3b/3Dmigoto/releases/download/1.3.16/3Dmigoto-1.3.16.zip) or edit your monitor with Custom Resolution Utility (link to the software) (https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU) by removing your lowest refresh rates and leave only the highest. This is necessary to avoid the 60fps limit.

If you choose to use 3Dmigoto you have to:

Extract the .zip file and enter inside the folder "x64" or "x32" for 32bit systems
Copy only the files "d3d11.dll", "d3dcompiler_46.dll" and "d3dx.ini" and paste inside the game folder
Edit the "d3dx.ini" and search "refresh_rate=60"
Remove the semicolon and change 60 to your highest refresh rate, 144 for example
(OPTIONAL) To remove the logging files change all the values in "Logging" to 0


SLI Bit "0x080000F1" give good performance without any problem and the testing was done with a resolution of 3840x2160 (2560x1440 + 2.25xDSR and 24% smoothness) without ingame antialias enabled. In some cases SLI Bit "0x080020F1" can improve performance, but at cost of some flickering or visual glitches.

Sorry for my late response. About your question, i am not sure. I can only refer to users with Pascal SLI and there it seems no real performance-gains. There are a few flags but this ones are mainly for NVLink.
But even under optimal conditions with Turing SLI/NVLink the results with new CFR-mode are very mixed (compatibility+scaling) there is still a lot to be done...

That's not the case and general a difficult topic, even NVIDIA has introduced new low latency features recently and it also depends on many other factors. G-Sync helps a lot to improve smoothness and avoid judder due to erratic frame variations especially in SLI/MultiGPU-AFR mode which is the case in all mentioned 3 games, it feels much better! In SLI-AFR mode there is no such NULL-support nor Low Latency Frame Limiter etc.

Halo Reach scheint nach eine Kurztest auch mit CFR zu funktionieren

[Kuzunkhaa]

Overwatch [Shadows FIX]

Well...Overwatch have an official SLI Profile, but a lot of SLI users have reported since the launch day, the annoying flickering of the shadows and the only solution was to completely disable them from the options.
Today I want to share with you a solution I've found by modify the official profile into "0x2C0120E1". With that tiny modification all the shadows are rendered perfectly, but in rare cases and only with few heroes like Torbjörn and Mei, we still have a little flickering ONLY in the main menu and in the "Hero Gallery".

About the performance the profile don't lower or increase framerate, so you can try without any contraindications.

Have fun and play fair! :smile:

Halo Reach scheint nach eine Kurztest auch mit CFR zu funktionieren

Danke für dein Feedback. Eigentlich sollte ja Halo Reach nicht so fordernd sein? Hast du bei höherer Auflösung verglichen um die GPUs besser auszulasten? Schreib doch mal ein paar mehr Details. :) Meine Game-Kompatibilitätsliste (https://www.forum-3dcenter.org/vbulletin/showpost.php?p=8881192&postcount=43) ist auch nur ein erster grober Überblick, ich werde sicher auch noch Änderungen vornehmen müssen, da enorm viel Zeit-Aufwand dahintersteckt um dies umfassend und vor allem auch korrekt zu tun, aber irgendwo muss man ja mal anfangen.

Ich hab 8k getestet alles max. also 4k mit 4x Downsampling

Ganz am Anfang vom Spiel erster Checkpoint.

Single 2080ti@2025MHZ 70-72fps

CFT 2x 2080ti@1965MHz 100fps

Die so schlechteren Taktraten im SLI kommt leider dadurch das meine 2te 2080Ti schlechter ist mit geringerem Powertarget. Eventuell mache ich ein BIOS update um das auszugleichen aber das hat nicht Priorität.

Updated SLI information for Dead by Daylight and Insurgency: Sandstorm

Another SLI update for Dead by Daylight

Updated SLI post
3DCenter SLI thread (#2913) (https://www.forum-3dcenter.org/vbulletin/showpost.php?p=11778542&postcount=2913)

Did some further digging around in the latest version of Dead by Daylight.
It seems the only real SLI solution now is to use 0x080040F1 combined with setting 0x00A06746 to 0x00010100.
This gives at least some consistent scaling, and every other custom profile causes one problem or the other.

SLI and AA information for Insurgency: Sandstorm

Preliminary SLI post

Another SLI update
3DCenter SLI thread (#3133) (https://www.forum-3dcenter.org/vbulletin/showpost.php?p=11904873&postcount=3133)

Just using the 0x080020F1 profile seems to be sufficient in the latest version of Insurgency: Sandstorm.
This scales well at native 3840x2160 resolution with TAA enabled on my 2-way 980 Ti system in PCIe 3.0 x16/x16 mode.
Testing was done using maximum settings, only with "Frame Rate Smoothing", "Motion Blur" and "Super Sampling" disabled.

However with SMAA T2x there is limited scaling as well as flickering and double images.
The flickering and double images can be fixed with another custom profile, but I found no solution to the scaling issues.
So posting about it or using SMAA T2x in SLI mode makes no sense in my opinion.
Not to mention that TAA produces a much better result in this title anyway ;)


After the recent patches to the UE4 titles Dead by Daylight and Insurgency: Sandstorm SLI behavior has changed.
Now there doesn't seem to be any useful SLI solution in Dead by Daylight.
I only managed to find a custom profile which scales slightly in the main menu, but it doesn't scale consistently ingame and might cause shadow flickering under certain conditions.
My recommendation would be to remove the game from the SLI list for the time being.

As far as Insurgency: Sandstorm goes, the only real solution is the basic 0x000000F1 profile which scales decent enough ingame in PCIe 3.0 x16/x16 mode on my system at native 4K resolution with TAA enabled (~ 50% scaling over single GPU performance).
However there is negative scaling in the main menu, which can't be fixed without breaking performance or causing flickering ingame.

Hello,

Im kinda new to this deal, but im trying along. I did fallow all extractions by mr. Blaire and somehow im stuck.


The Division 2

- dx11 goes in , but after 20 sec yellow light starts to fade in and its all in yellow light, i can move,... but u cant see nothing else, its like a tick fog of yellow light.

Battlefiled 5

- dx11 or dx12, goes in but too many grafic issues.


Is there anyway to make it work mGPU on this titles? and if yes, can someone share it?

Thank you and i realy hole SLI is not dead yet. :cool:

Has anyone had a chance to test World of Warcraft with CFR yet? With the latest expansion, Blizzard removed exclusive fullscreen, which pretty much broke SLI, so I'm curious as to whether or not CFR and NVLink will work well with it. The game currently has three graphics APIs: DX11 Legacy (single-threaded), DX11 (multi-threaded), and DX12. I'm about to build a new computer, and I'm very interested to know if CFR works in any of the three graphics API choices.

Thanks!

I've built the following nip file based on this but the perf in 4k are awful (10fps less than on a single card), probably missed something.(i'have two 1080)

if someone has an idea? thx

The Outer Worlds - Pre-Turing SLI functionality:

https://www.reddit.com/user/allenhaeri/comments/dosy6v/the_outer_worlds_sli_profile_for_non_rtx_gpus/

Has a nip file and also go down in the comments to mod the engine.ini file via the mod referenced in the link on Nexus Mods - you mod the engine.ini file to turn TXAA off so that SLI will work. Games runs good for me now in 4k. 2x 1080 Ti.

[Razrback16]

In 16K ?

? I'm not sure what you're asking. You mean 16k resolution? If so, no I am running 4k resolution. Not really concerned for Halo Reach as 1 1080 Ti runs it in 4k perfectly, but more for the later games like Halo 4 that is more graphically demanding.

On my first look the D3D12 version it seems to work and allows up to 40% performance-increase in GPU demanding scenes @ 5120x2880 resolution (windowed fullscreen). The DX11 version is apparently limited to 60fps with 60 Hertz displays because of windowed fullscreen-mode. I will test it later with my Asus PG27UQ 144Hz again.

Ich hab mir das Game im Steam-Sale gekauft, ja die Bildraten bewegen sich hier im vergleichbaren Bereich mit CFR. Aber auch AFR2 scheint für 8K-Auflösung und 120fps (mehr scheint nicht möglich) auszureichen und gefühlt besser als 60-70fps mit SingleGPU.

Resident evil 2 remake with CFR is a pleasant experience unlike AFR which gives stutters. The problem is that I get random freezes. I have never gotten any crashes/freeze in RE2 with AFR (65 hours played).

Can anyone with RTX gpu's spare some time and test this?

Also I don't get why it is possible to get mgpu scaling with vulkan API games like (RDR2, quake 2 rtx) but not others like Rage 2, The Surge 2.

[austinminton]

I had practically given up on using my 2080ti nvlink setup for new games and stopped looking at this thread. CFR is great news indeed! I managed to get dx12 + Ray tracing with my sli running well using the steps described by Blaire earlier. Happy to try on RE2 next but I am just a bit confused on the bits needed. Should I just use the 0x00000002 bits or should I first find the sli bits for the game and then substitute the last digit by 2?

No. I only noticed inconsistent performance when changing between real fullscreen and windowed full screen mode in DX11 version. Do you refer to the DX11 or DX12 version of the game? Please share some more details.

Just use always "0x00000002" with no additional SLI compatibility-bit's ticked "on".

I finally got most of my setup dialed in, and I have to say that CFR brings multi-GPU performance gains back to World of Warcraft, after they were lost with standard SLI setups and windowed mode. Everything is buttery smooth at 4K with cranked up settings and several ReShade presets applied, and I've not noticed any stuttering, hitching, or mysterious drops in framerate.

This is great news, and while I hope nVidia continues to improve upon CFR in the future, I'm glad that they "secretly" released it for us to play with.

Yep. Another nice addition is that CFR-mode also improves input-latency while increased performance over SingleGPU, it was never possible with AFR + buffered frames. Even if performance-gain is not as big, you can still feel the improvement. :)

Weisst du was das macht? Ich hab das mal einfach auf 0x0000000 gestellt und habe keinen unterschied bemerkt.

Eigentlich bleibt es sich gleich und zieht keinen Nachteil nach sich, aus Kompatibilitätsgründen würde ich auf weitere Ziffern im Code verzichten.

CFR is really impressive, getting smooth gaming on RE2 with no issues yet. Have played about 45 mins with no crashes. Big thank you to Blaire for this discovery and then responding to our queries. Happy New year to you too, hope we all have a great year with SLI thanks to cfr!

Another win for CFR, Quake Champions. It works okay on AFR but has occasional stutter and increased input lag. With CFR there is no stutter and no visible input lag. Extremely impressive!

[Arhat1984]

No. I only noticed inconsistent performance when changing between real fullscreen and windowed full screen mode in DX11 version. Do you refer to the DX11 or DX12 version of the game? Please share some more details.

I use DX11. Tried again but got no crashes or freeze, I don't know why.

I always get inconsistent and jittery performance on nearly all games when I don't use exclusive fullscreen aka true fullscreen.

Has anyone tested this with any sort of VR software stack? Getting DX11/12 games in SteamVR direct mode to support SLI scaling at a driver level is the literal dream man. VR is so much more resolution hungry than flat screen.

So yea it would be great if someone could test out 2x Turing CFR on SteamVR, Oculus SKD game, native WMR application, etc.

Unforunately with my Index and SteamVR only the left eye gets an image plus the rendered image shows only one tile rendered and the other one is black

Happy New Year all,

I was hoping any of the last bastion could help in diagnosing and possibly resolving the following issue, it occurs on an SSR disabled, hex edited exe for metro with the profile on the forum. It also occurs with Anthem, I have had an open bug report with Nvidia for some time on it but hit the limits of what I could add, hoping the fine folk here could. All other games, both Nvidia and this forum created, all at max settings 4k or as close to max as possible, Destiny 2, The Outer World's , Shadow and Rise of the tomb raider all work without issue, and while not all game engines are created equal, I would have expected everything to work or fail the same if this was hardware.

Firstly i have uninstalled all of the MSI software except true colour, i have also installed XTU and Precision X1 and have overclocked and undervolted the CPU to 4.0 all core and -40mv underclock, have raised the cache to match at 4.0mhz. I have also tightened the timings of the 4 DDR4 ram sticks to 2400mhz at 15 15 15 35.

The GPUs are coupled and run at an overclock of 170mhz on the core and 600mhz memory, with and without the overlocks the issue occurs. I have had issues with Destiny 2 switching to HDR, but it is disabled at windows level and the latest patch for destiny resolved this, I have it connected to a LG C9 which is capable of HDR, but it is connected with USB C running DisplayPort 1.2 bandwidth, which does not support HDR and when running it it causes some orange tint colour explosion, so I turn it off but have noticed it switches without permission on that game, maybe this is the root cause?

But what makes me hesitate to fully believe this is i also have the issue on the laptops native display, which is not HDR capable. I have done various DDU uninstalls, uninstalled from device manager etc with no luck. The glitch is always present and occurs after a brief time playing, in regards to specs, i run them all as close to max as i can compromising on AA, running all games at 4K with no Temporal reconstruction or upscaling active.

Thanks for your answer. Short Question, do you had GeForce Experience installed or his Share-Overlay active while this was happening? I could also see this black square-issue yesterday on the wolka-map, but with an RTX 2080Ti and the DX12 version of the game, but I have no idea how to trigger it, but it happened while opening the GFE Freestyle-function with ALT+F3.
I haven't been able to narrow it down yet since it has only occurred once, but it doesn't seem to be really related to SLI on my end.

No problem Blaire, thanks again for the assistance, I did have it installed and active when i shot the video, and when i have experienced it now and in the past. I rarely activated it though, as i don't tend to use the features, using it while playing the game only once or twice to record game footage, but disabling it for the majority, with the toggle for the overlay disabled but geforce experience still installed.

As part of my troubleshooting i have uninstalled it, set compatibility to windows 8, disabled fullscreen optimizations and override display scaling to run through the app, all efforts unfortunately failed. However, whenever i changed the vsync options it would create the glitches, though i have not tried any other setting, and it could be triggered by changing any settings, as changing the shader rate will temporarily resolve it but it comes back almost instantly.

I haven't been able to narrow it down yet since it has only occurred once, but it doesn't seem to be really related to SLI on my end.

In another late addition to my first reply i have taken longer video showing it becoming more prolific, and hopefully adding more data about the scenarios which cause it, as the sky also aggressively flickered.

Apex Legend hab ich nicht. Das ist aber Free to play oder? Mal schauen.

Hast du eine Liste von DX12 Spiele die Multi-GPU unterstützen. Ich hab mich ein bisschen mit Frametimes befasst zwischen AFR,CFR und Single. Würde gerne mal ein paar Tests bei DX12 und AFR machen.

Ist Free-to-Play ja. Eine spezielle Liste hab ich da jetzt keine, denn die Anzahl unterstützter Games ist dann doch noch recht überschaubar, aber neben den bereits erwähnten Games, fielen mir da spontan noch Ashes of the Singularity, Strange Brigade, Sniper Elite 4, Battlefield 1 oder auch der erste Hitman ein, welche nativ DX12 MultiGPU-Support bieten.

Hi. Yes it runs in CFR Mode :up:

I have 980ti's :(

Im Beyond3d Forum https://forum.beyond3d.com/posts/2098297/ hat jemand das Patent gefunden was wahrscheinlich das CFR beschreibt.

Ist jetzt nicht überraschend für mich, ich kannte das Patent bereits zum Zeitpunkt, hab aber bewusst verzichtet dieses zu verlinken, da ich mir etwas offizielles erhoffte.
Mit dem nächsten Treiber-Branch ist der öffentliche und ungewollte "Feldversuch" dann leider auch schon wieder beendet und CFR nicht mehr verfügbar.
Da werden wir uns also noch gedulden müssen, bis man da von NVIDIA mehr Details erfährt.

Dropping CFR is indeed unfortunate, it had excellent results in some titles and showed promise for future titles with its support for dx12. Hope they release it officially soon.

Das ist natürlich schade das sie es ganz entfernen. Kann auch sein das Hardwaremässig noch etwas fehlt(bei turing) um es mehr kompatibel zu machen und vielleicht wird man dann etwas für die nächste Generation an Karten sehen.

That would be a strange reason to disable CFR i think (or something is getting lost in translation?). It was a feature which worked well with the current hardware with useful features like dx12+rtx support, less lag etc. Its not something an average user can accidentally enable on the control panel but requires an advanced user. Such users would be open to things not working properly and would be happy to tweak it. It was simply amazing what Blaire achieved with CFR testing and how many titles worked well with it. They could have easily left it in the new drivers and we would have happily tried out future titles without complaints. If nvidia can enable rtx for non turing cards, they can surely leave a decently working feature like cfr in the drivers.

Some of the reasons I can think of would be:
1) Some new features were added in the new driver branch which breaks CFR and since its not an official feature, they are happy to release new drivers and work on fixing CFR later for this branch. This is the optimistic scenario.
2) It was a feature not meant for the retail customer and was actually meant for platforms such as game streaming servers. We might never see it enabled again in drivers meant for end users like us. This is the pessimistic scenario.
3) Another reason could be they received criticism that its only for turing and doesn't work on pascal etc.

Either way its disappointing that we dont get CFR in the new drivers.

Well i think as it stands nvidia would have never official released CFR as a feature to the public. While yes it works in some games there is just to many problems with it to promote it as a official CP feature. In a lot of games it produces artifacts or even crash and when it works the performance increase with 30-50% would disappoint many users i'm sure , but yes i agree they should just keep it in the drivers for users like us to play around with it.

Ja so ein Mist. Man kann echt nur hoffen, das Nvidia es doch wieder einfügt oder es bald offiziell macht.
Habe einige Spiele getestet und es lief teilweise echt super :up:

Bleibt nur eines - zum testen einfach den Treiber nicht aktualisieren...

P.S. Übrigens läuft der Flight Simulator 2020 Tech Alpha super mit CFR im Spiel - gibt einen ordentlichen Performance Schub :)

This is incredibly unfortunate to hear, and it seems odd that they wouldn't just keep CFR present and hidden, in the driver, like it currently is.

Even in its development state, CFR has allowed me to play WoW in DX12 with a multi-GPU setup pushing ultra settings at 4K (with added AA) along with several resource-intensive ReShade presets on top of that, all while in windowed mode, which is something neither a single GPU can accomplish, or dated AFR in DX11. Every time I fire up the game I'm still in awe as to how smooth the experience is with a multi-GPU setup, again, while running in windowed mode, and I'm constantly looking at my MSI AB overlay to ensure that both GPUs are actually engaged (and they always are).

I guess I might be forced to turn into someone who refuses to update, clutching onto a particular outdated driver branch so as to not lose, arguably, the feature that has excited me the most, and allows me to properly utilize the hardware in my system. If CFR isn't here to stay, then nVidia's ability to sell me multiple GPUs continues to dwindle.

I did try, it wasn't working and I didn't see it here. The normal sli bits never worked for me but I heard people saying it does so I thought maybe someone could share there personal sli bits. Thanks anyway. **Edit: Oh shit I never even knew that a master section existed. Thanks for the link!!

[Yz_Soebodonk]

Ich wünschte die einzelnen Grafik Detail-Settings wären mehr transparent und individuell anpassbar, doch leider gibt es nur vorgefertigte Detail-Stufen. Denn mit nur "Medium-Details" skaliert SLi sogar recht ordentlich, mit zwei RTX 2080Ti erreicht man dann schnell zwischen 35-60fps bei wahnwitziger 7680x4320 Auflösung! "High", "Ultra" oder "Extreme"-Presets skalieren im SLI dann leider nicht mehr vernünftig.
Trotzdem , das könnte ein guter "Trade-Off" sein, für Leute welche eher ein knackigeres Gesamtbild vorziehen, statt eher subtiler Schatten-Spielerei. ;) Möglicherweise gibt es ja einige Ingame-Console Commands welche man nutzen kann um die Möglichkeiten mit SLI besser auszuschöpfen, aber dazu ist mir bisher zu wenig bekannt.
https://abload.de/img/metro_exodusr5jcy.png
https://s1.imagebanana.com/file/190219/thb/nSZrMryw.png (https://www.imagebanana.com/s/1338/nSZrMryw.html)https://abload.de/thumb/metroexodus-settings-30kty.jpg (http://abload.de/image.php?img=metroexodus-settings-30kty.jpg)https://abload.de/thumb/metroexodus-settings-hwjrt.jpg (http://abload.de/image.php?img=metroexodus-settings-hwjrt.jpg)
Update 4.3.: Einem Youtube-User ist es geglückt per EXE-Modifizierung bessere SLI-Skalierung freizuschalten , nachdem die Ingame-Optionen ja wie bereits von mir erwähnt, nur sehr spärlich Einstell-Optionen zulassen scheint dieser Weg mehr Möglichkeiten anzubieten. Wenn man den Eintrag "meta_ssr" mit "........" in der originalen "MetroExodus.exe" (Unter "Steam\steamapps\common\metro exodus) ersetzt, funktionieren dann auch die Grafik-Presets "High" , "Ultra" und "Extreme" mit SLI in angemessenen Rahmen und guter GPU-Auslastung zweier GeForce-Grafikkarten!
Die Screen Space Reflektionen werden offenbar auch nur zum Teil deaktiviert, genauere Vergleichstests werden ich noch vornehmen, aktuell finde ich diesen "Tweak" sehr brauchbar @ Credits to YT-User "Kamiccolo Freeman (https://www.youtube.com/watch?v=Xc7SmXtdmiQ)"

Zitat Kamiccolo Freeman (https://www.youtube.com/watch?v=Xc7SmXtdmiQ) (Youtube-User):
"To enable sli in Metro Exodus you need to modify the metroexodus.exe itself in a hex editor. I used Hex Workshop v6.8. You need to find (meta_ssr) and replace it with (........) essentially removing forced screen space reflections when using high, ultra and extreme preset. This is pretty easy to do open the metroexodus.exe with Hex Workshop. Then press control F and search for (meta_ssr) in text."

Allerdings ist das von ihm verwendete SLI-Profile nicht brauchbar, da es Flackern bei verschiedenen Lichtquellen, als auch schwarze Balken verursacht und den Inputlag durch den verwendenten SLI-Hack erhöht, das kann man so dann nicht zu 1:1 übernehmen...
Ich hatte daher versucht, das Profile etwas zu "entschärfen" um mögliche Grafik-Probleme/Corruption eben so gut es eben geht zu minimieren!
Eine erste mögliche alternative Profile-Variante wäre diese hier, allerdings muss ich das noch etwas ausführlicher checken und das dauert einige Zeit... Getestet wurde diese mit 2-Way RTX 2080Ti @ NVLink mit 5120x2880 Auflösung , "Extreme"-Preset, Tessellation + Hairworks + Advanced PhysX aktiviert mit der aktuellen Steam-Version 1.0.0.2.

Updated SLI information for Dead by Daylight and Insurgency: Sandstorm

Another SLI update for Dead by Daylight

Updated SLI post
3DCenter SLI thread (#2913) (https://www.forum-3dcenter.org/vbulletin/showpost.php?p=11778542&postcount=2913)

Did some further digging around in the latest version of Dead by Daylight.
It seems the only real SLI solution now is to use 0x080040F1 combined with setting 0x00A06746 to 0x00010100.
This gives at least some consistent scaling, and every other custom profile causes one problem or the other.

SLI and AA information for Insurgency: Sandstorm

Another SLI update
3DCenter SLI thread (#3133) (https://www.forum-3dcenter.org/vbulletin/showpost.php?p=11904873&postcount=3133)

Just using the 0x080020F1 profile seems to be sufficient in the latest version of Insurgency: Sandstorm.
This scales well at native 3840x2160 resolution with TAA enabled on my 2-way 980 Ti system in PCIe 3.0 x16/x16 mode.
Testing was done using maximum settings, only with "Frame Rate Smoothing", "Motion Blur" and "Super Sampling" disabled.


After the recent patches to the UE4 titles Dead by Daylight and Insurgency: Sandstorm SLI behavior has changed.
Now there doesn't seem to be any useful SLI solution at all in Dead by Daylight.
I only managed to find a custom profile which scales slightly in the main menu, but it doesn't scale consistently ingame and might cause shadow flickering under certain conditions.

As far as Insurgency: Sandstorm goes, the only "solution" is the basic 0x000000F1 profile which needs minimum PCIe 3.0 x16/x16 mode to scale at native 4K resolution with TAA enabled.
However there is negative scaling in the main menu and on some bigger maps, and even disabling bandwidth intensive settings like TAA makes no difference on my system.
Most likely NVLink is needed to completely cure this problem.

Here are some comparisons taken on respectively the "Crossing" and "Farmhouse" maps:

Single GPU|2-way SLI

Thanks again SLI Knight, i m really like INSURGENCY Games..

0x000000F1 Bits doesnt scale fine with my 2x 1080ti 16x16x both gpus are @50% i have just 60fps where One GPU give me 120-140 Fps

[SLIKnight]

Well, I'm not sure what is wrong then.
Perhaps you are running into some type of CPU limitation then.

All I know is there are no alternative solutions for now, since bit #27 causes terrible flickering.

Just turn up the resolution then :)

EDIT 15/2

Updated my SLI post above.
The "F1" profile is definitely the only solution in Insurgency: Sandstorm right now.
Any occasional negative scaling is simply another PCIe bandwidth and/or CPU limitation.

CFR funktioniert mit Halo CE bei der MCC. Sehe ca. 35-40% scaling mit 4k 4xDSR mit 2x2080ti

Has anyone here heard of any type of news about dual gpus in laptops or any plans of trying to implement Nv link in laptops or is dual GPUs dead for laptops? I guess it's kind of bad for business to have a laptop faster in some cases than a 2080 TI (gtx 1080's)

Btw fallout 3 sli doesn't work anymore it for Pascal or Maxwell it shouldn't be in the supported section.
Also Is there sli for saints row 2?
Could we maybe try fixing sli other then in battlefield 1 and Dead by Daylight and Insurgency: Sandstorm?
Btw not ever has rtx it would be great if we had more people working on Pascal too, did you know that 2 gtx 1080s (with good sli scaling) beats a rtx 2080 ti?

Does Terminator resistance have sli support? Is there a way someone could help find sli support?

Thanks for the reply. Was that recent or old? Because I'm talking about now.

Just cuase 3 sli? I could have sworn it worked. Can someone try and get it to work?

[1415gateway]

Does Terminator resistance, just cause 3 have a possible sli fix for Pascal cards (GTX 1080s)

[Blaire]

Does Terminator resistance, just cause 3 have a possible sli fix for Pascal cards (GTX 1080s)

Please stop begging. For Just Cause 3/4 you won't find anything, the same goes for Terminator Resistance (requires Pascal SLI + HB-Bridge in x16/x16 PCIE 3.0 mode)

Hi! I have recently run a Doom from 2016 on new Windows and I have found out that default profile from Nvidia is terrible for me. I found on my computer some old custom profile and it is good as I remembred. With 2x970, 1440p, except shadows all on nightmare, I am able to get around 90-100 fps, when before I was struggling below 60.

I did not find it on the list, so I enclose it here to not make it lost :).

EDIT: It seems, I've doubled profile from Blaire: https://www.forum-3dcenter.org/vbulletin/showthread.php?p=11034642#post11034642
Excelent work, many thanks! Feel free to delete my post if you think it will cause confusion.

Play at DOOM (2016) on Vulkan you will have better FPS with one GPU than the SLI on OPENGL

[Meph]

Well, actually, not exactly. Below you have the same scene, with the same settings on Vulkan.

I still remember with two GTX1080 "Pascal" despite the HB Bridge this game doesn't scale well in OpenGL SLI mode, so yeah two GTX 980Ti however actually can handle this game much easier (better gpu-utilization) and offered a better gaming experience.
Now with two 2080Ti @ NVLink and tons of more bandwidth these "design-flaws" and limtations are no longer exists, the official SLI profile scales perfectly fine. up to 7680x4320 resolution.

[Suzerain]

^Yes, can confirm Doom (2016) works well with NVLink SLI with OpenGL.

Has anyone gotten mGPU with Vulkan in Doom Eternal to work? Forcing CFR crashes the whole game - doesn't start - only get black screen.

What about Resident Evil 3 Demo? CFR works but randomly crashes game with 'fatal error.'

[Noiseovore]

Happy to see SLI works for you on DOOM (2016)
that's not my case with 1080Ti and HB
SLI on OpenGL with Blaire's Profil 130fps in this place:

Hey everybody! This is an updated post for Battlefield 1 Sli Fix.

This profile incorporates removing ScreenSpaceRaytraceEnable from the bf1.exe using a hex editor. Doing this fixes lopsided gpu usage with 10 series and below. I do not own NVLink but this should help with sli utilization on nvlink series too.

Here are ingame photos to show the scaling for ssr on vs off with both sli on and off. 3440x1440 all ultra 200% rez scaling (6880x2880) Enjoy :)

i've made differents games on PUBG with this SLI Profil (https://www.forum-3dcenter.org/vbulletin/showpost.php?p=11832501&postcount=3015) using FXAA (AA on Medium)
I havent experienced any crashes.

Did You try different Drivers, often game crash are due to the drivers.
I used the Nvidia drivers 442.19, the lastest versions crash The DIVISION 2

[Mr_exit]

Hello,

Is there any idea how to make Doom Eternal SLI mode?

Thank you, Exit

p.s.: The Division 2 still no profile for SLI?

DOOM Eternal actually run only on VULKAN, devs havent implemented MGPU

The DIVISION 2 run on DX12 and DX11: DX12 doesnt have MGPU support and DX11 doesnt have viable SLI Solution.
Maybe CFR must work on NVlink

Hi everyone. First of all a big thanks for these forums, they have solved so many gaming sli problems. I have an Sli problem with several games, but now mainly with Star Wars Jedi: Fallen Order. I know the latest drivers support SLI, but somehow on SLI i am getting 25 - 30 fps, with both cards at high usage. This happens on all settings. However, if i use a single card i get 40fps. Is there any particular setting i need to input? thanks

I have tried everything, rolling back drivers, new drivers, reinstalling game. This is not the first time that it has happened with a game. I have two 1080ti in sli. There have been many games where, sli profiles were available, other have the exact same build as i do, but i get 30 fps on sli and 40 or higher on single card. Any ideas pls?

Your SLI is on PCIE X16/X16?

Your SLI is on PCIE X16/X16?
It's on the 1st and 4th slots. Above the slots it says "PCIE 16/8x2". I've had this problem with many other games

Unreal Engine 4 games have high bandwith usage where SLI on PCIE 16x 16x is really needed

EDIT : i just try the game, Official SLI works but the lastest drivers seems to have less performances

I understand doom eternal is vulkan only, but this line from the latest drivers caught my eye

Windows 10 Issues

Does that mean they are looking at SLI for Doom Eternal?

good morning friend. which are the best drivers according to your opinion for a SLI GTX 1080. I have tried star Wars jedi with the latest drivers and it is true that the performance is low but the SLI runs. Sorry if my English is bad but I am from Latin America and I use the google translator to learn from your SLI knowledge. Thanks everyone for creating this great theme: D

The best drivers with more smoothness and sensation of G Sync with sli so far are the 416.94 for the SLI GTX 1080 in my opinion if another has a better option than comment thanks

Same problem. The person who posted the profile even says:
I just want to share this profile for RE2 that I've been using myself and personally haven't seen any flickering or game-breaking bugs besides "darker screen"

Both profiles give outstanding scaling but with a catch.
