Trying the SLI profile provided earlier in the thread but Nvidia Inspector will not let me import it.  I exported the existing profile, updated it with the changes supplied by Saijan, then tried to reimport it but it just errors out and says "Profile Could Not be Imported".  It does not supply a reason.
 
How do you import an updated profile if Inspector won't let you?

I truly don't believe the ERR_GFX has anything to do with GPU clocks, for 1 with same clock a single GPU and even being Overclocked it will run all day and not get it a once, but soon as you enable SLI it comes up every few hours. If Inspector will not import then you can try a program called Geforce 3D Profile Manager which can be found here https://nvidia.custhelp.com/app/answers/detail/a_id/2625 inspector can be picky at times. 

Yeah as of .41 SLi works. In .66 they say they updated the Performance profile for RDR but I think it was just carried over from .41 because a lot of what .41 did they said it again in release notes. Having to wait till my water stuff comes tomorrow before I can give SLi another go have a 2080ti tore apart sitting on my workbench because I ordered the wrong cooler. Anyways I hope they add some performance fixes and other stuff with the new update on Friday and not just content.

Any performance uplift on .66 ?

Not that I can see on single card, water block should be here today so I can have my second card running again. I did manage to tweak graphics to be able to get a average of 60fps @ 5120x1440 on a single 2080ti and you will have to look hard to tell the dif from everything on Ultra which was a 45 avg on a single. Also simply turning on Async Compute in the system file gave me about a 3fps boost on the avg framerate not huge but everyone counts when trying to hit that 60 mark in this game. So as it stand 30fps min, 125 max and 60 average.

So does anyone know why 1 of my 2080 ti refuses to go beyond 25-30fps regardless of title? I do a straight swap with other card no driver uninstall or setting change and it get 80fps in 1 title and other card 25. In RDR it struggled between 25-35fps other card 50-60fps? So when you put both in and run SLi fps is worse than a single card. Also the clock speeds and temp seem normal 65c and running in the range of 1300-1950mhz on gpu and 7000 on mem. So I just don't get it lol

What kinda AA are you guys using? I used to use TAA, high. But it seems to me that the image is very washed out. You see it especially on the vegetation, like the threes for example. Tried to switch to msaax2, but that eat my FPS. FXAA is way to “sharp” I think. I think I have found my middle grown with, TAA, medium and FXAA on. I run SLI(2x2080ti on custom water) and the resolution of 3440x1440.

I’m eager to hear what you guys are thinking and using. :-)

Edit: and does g-sync work on the game now? For us that have SLI? I have an lg freesync 144hz monitor, that is g-sync compatible/verified.

I have SLI 2080 Ti.

I’ve tried everything, but I can’t get rid of the flickering during certain cutscenes.

Is anyone running 2 2080 Tis experiencing this issue?

I’m about to give up on the game.

Literally everyone in this entire thread is having the same issue when SLI is enabled. Did you not bother to read any of it?

Sorry, I should have said: is anyone using SLI 2080 Ti NOT experiencing this issue?

Your answers are in the thread you asking them in.

I’ve read the whole thread, and it is still not clear whether someone is not experiencing this issue.

I do know that most people are experiencing it.

I would like to understand if someone is not experiencing it and ask them if I need to do something specific to resolve the issue.

How can I find out without asking?

Do you know the answer?

All of a sudden. I now have with my 2 X 2080Ti Setup, 10-15 FPS.. max... unplayable.  Tried optimizing, tried setting manually to medium settings and also back and forth from DX12 to Vulkan..
 
WHAT GIVES??
 
I am still shocked that its december, I have a liquid cooled SLI 2080 Ti and I9 and still this game SUCKS to play... unreal

FEARLESS_FARGO
Same here. Performance is absolute trash now. And I get this insane flickering and color issues.. This is horrible. Im running SLI 1080ti's with Nvidia Driver Version 441.12

You can’t even try to set profiles, update the driver to version 441.66, turn off TAA)))) This will not help get rid of flickering)
P.S. Here is an example of my flickering:  www.youtube.com/watch?v=5-yI0ucl3cg
P.P.S. I`m use 2x gtx 980 )

I can't even get the game to run in Vulkan anymore.  It ALWAYS throws the ERR_GFX_STATE message and crashes.  The menus work, but as soon as I attempt to enter the actual game, it crashes.  This is with SLI enabled AND disabled.  I have tried every fix listed online and nothing works; The game cannot be run in Vulkan.  DX12 works fine, but of course SLI is not supported making it impossible to run the game in 4k on Ultra settings while retaining a reasonable frame rate.
 
**Edit**
I stand corrected.  The game will not load at ALL in Vulkan.  There is no error, it just closes itself.  This is after the update they just released.
 
**Another Edit**
The game no longer loads at all unless I enable Safe Mode.  DX12 or Vulkan both crash with no errors.

Did you delete the sga files as posted earlier in this thread? Also just FYI Vulkan will still attempt to use both cards even when it disabled. The only way I got vulkan to work with a single card is by removing the card, hell I also removed the Nvlink off the cards and vuilkan still tried to used sli and fps was crap lol. For me DX12 is trash and about a 5fps decrease over Vulkan. Just got replacement card about to try SLI again, will update as to what happens for me.

Yes I removed the SGA Files.  I've tried literally every "fix" I could find online, to include everything mentioned in this thread.  The game actually functioned in DX12 until they released this update (Moonshiners).. now it won't launch at all.  I'm in the process of reinstalling it on a different drive right now to see if that makes any difference.. Could have had a corrupted update.  Last ditch effort, I'll remove 1 of my GPU's and see if NVLINK being connected (albeit disabled) makes any difference.  Pretty sad I'd have to do that to even get a game to launch.. Other games are working fine with SLI (Like Witcher 3, Black Desert Online, The Forest, etc).

Does it freeze or just crashes to desktop. I know I used to have a issue with full screen it would just go black and would have to alt tab and back. I run borderless window mode. Removing the nvlink didnt work for me I had to remove the card completely to get Vulkan to run a single card.

I just ran sli and it loaded just fine. It seems to be better for me than before, card used to be both 98% and would heat up quick, bow they are high 80s like around 88%. The benchmark completed with high of 143 and avg 93 fps at 5120x1440. It gave me the err in the middle of a moonshine mission. I deleted the files and will test again when I get home, had to run to airport. What cards are you running?

I have an EVGA XC2 Ultra and a Zotac Amp Maxx.  The XC2 ultra has an AIO cooler installed and never breaks 50 degrees.  The Zotac uses its stock cooler (no way to install an AIO without custom modding something; It's not a reference board), but the max temp it's reached has been ~70 degrees.
Kind of disparate cards I realize, but again they work fine in every other game that supports SLI.  My CPU is an i9 9900k, 32GB DDR4 3200mhz.  Tried installing first on an NVME SSD from Crucial, now tested on a Sandisk SATA3 SSD.
 
After reinstalling the game to a totally different drive, the game still will not load.  It just closes itself and says it closed unexpectedly.  Weirdly before I launched the game it claimed there were "unexpected files" in the installation directory, which is impossible since I installed it to a different drive and the only files in the directory are the ones Rockstar themselves installed.  I checked the installation folder but I don't see any files that shouldn't be there.
