My 1080ti SLI (441.20 DDU install) works pretty well now. GPU Usage is at 99% on both cards.
Disabled Gsync on global settings, not in the game profil. I didn't change anything in the driver or via nvinspector.
Every setting on ultra, only water slider on 75% in the extendend settings.
To get a smooth experience, i had to activate vsync ingame. Triple Buffering makes no difference.
Rarely i get a flickering heaven, but if a cutscene starts, it stops.
 

SLi does work with 441.20 and above so there is clearly something set wrong either on your system or in the game itself. Nvidia also released a Hotfix driver yesterday for people stalling on 4 and 6 core CPUs. So if you would like someone to help your try and figure out which problem it for you I'd be more than happy to. But to just say SLI doesn't work F you isn't going to fix anything :). I run a 9900x @ 4.8 with 2x 2080tis all day long granted its not perfect and you get a little flash during load screens at times and occasional sky flash here and there but it does work. I run Ultra on everything except the slider for water is down 1 notch and I get 80 avg and 165 max @ 5120x1440. Also just using Force AFR works or simply adding it to the GTA V Profile there are a number of ways to get SLI working but HDR and SLI doesn't play well together and causes really bad screen jitter. If your on 441.20 you don't have to do either one of those methods.

The new update is giving me ERR_GFX_STATE errors randomly. Grr.. so aggravating.

No issues here. You must have your gpu's overclocked too high.

What resolution are you playing at? How much MGPU scaling are you seeing?
 
I can get some scaling if I disable g-sync but it's not that much and... I shouldn't have to. I didn't buy a $1500 monitor to have to disable a feature.

I'm playing at 1440p. Scaling is about +20fps in every situation. Didn't test the hotfix driver yet, hope to see some more scaling.
Would like to play with g-sync too, but at the moment it is like it is. The only possibility is to report it and hope for a fix.

Hi

I keep considering buying but how do you think it would play out with a 5930k and dual Titan Xp’s?

It depends on what res your wanting to run with Titans. When I was playing around trying to get SLi working I installed my 2x Titan XPs and was getting in the 50s I do believe. This was everything maxed out at 5120x1440. But say if your running or if I was doing say 3440x1440 it would probably be in the 70s range and this was before all the patches and driver updates.

Im running two 2080ti's they are scaling and I'm seeing massive framerate increases but most definitely Gsync isn't working.  I get a smoother experience with one card with gsync (lower graphic settings obv) than a higher framerate with two cards and no Gsync. I really hope this gets fixed sooooon.  Hopefully next patch or so.

I also get the ERR_GFX_STATE error on occasion since the update and my cards are the reference models fully stock with zero issues in any other SLI capable game. They will auto boost to 1980Mhz and settle around 1850Mhz or so once they've warmed up.
 
When it's running though it's nice and smooth but there is still slight flickering occasionally in the sky or during a cutscene. Most of the time it's mostly flicker free thankfully, but still something that needs fixing along with MGPU stability. 

If you do the delete the sga files mentioned earlier in this post it should clear of the ERR_ error unless you have already tried that or at least it did for me with my 2080ti Sli setup. Now I just get the random closed error lol or sometimes when I first enter a town which I think both of those are part of what was suppose to be fixed in the last few updates but clearly not for me. I tried the under clocking and it did nothing for me and my temps never get past the 85 degree mark.

Ok thank you.. So I have Intel I9-9900K, SLI 2080 Ti, nothing overclocked..  I did upload a profile from the start of this thread a while back but then I deleted anything RD2 related in that profile thinking it would overwrite as default.. maybe it did, maybe it did not. But I am getting most things to ultra at 4K res and avg around 45FPS during gameplay with a single GPU.. Would love to see SLI work.. also, 441.20 confirmed. Thanks

I have added the second 2080Ti and although the cards are using 90% each, the game seems laggy as hell. Tried GSYNC on and off. TAA needs to be medium. 
Hopefully they fix it. I want to play in Ultra settings at 4k

So SLi is working for you now with 441.20? I always DDU drivers after playing around with profiles and seems to work pretty well for me. Ive tried just about everything in the world to stop the random unexpected error and if I do recall when I tried a single card and dx12 it was even worse so going to give it another go with a single Vulkan.

Nope, I get single card only.. I have not done the DDU yet was hoping to avoid that.

You do have the API set to Vulkan correct because it doesn't work with DX12?

They released a updated 441.20 driver today also but think its mostly for JEDI and the new card release haven't had a chance to try it. I also have to use borderless wndow mode because of map not scaling for Super Ultra Wide unless someone know how to fix this for full screen. The map does fine on my wide in full screen mode but not for 5120. I can export my RDR2 profile if you want, for awhile I was using the .20 profile with the version before to see if it took care of the randoms because it seem to have started with .20.

441.20 is already a couple weeks old I think. They’ve release a hot fix driver, 441.34, which won’t appear in the normal Nvidia driver page so you’ll want to search for that. It’s supposed to fix issues people with certain 4 or 6 core i5 we’re having. I haven’t tried it yet, but as soon as I’m done with Star Wars Jedi Fallen Order I hope to jump back into RDR2 with the latest hot fix and game updates. 9900k w/ 2080ti SLI here, was experiencing crashes every 15-45 minutes before these most recent updates. Am hoping they’ve fixed something as I don’t want to continue playing this game until they’ve fixed the stuttering and crashing issues.

My 1080ti SLI (441.20 DDU install) works pretty well now. GPU Usage is at 99% on both cards.
Disabled Gsync on global settings, not in the game profil. I didn't change anything in the driver or via nvinspector.

Good to see your getting scaling I am not with my 1080's in sli. With my settings currently (one notch under quality "balanced") 4k res:
DX12=1 card 95% usage 34fps
Vulkan=1 card 90% usage 30fps
Vulkan=2 cards 60% usage 28fps
SLI=bad frame times and flicker occasionally
RDR2 build 1207.73 nvidia driver 441.34
CPU=5960x@4.3
Hope they can get the Pascal scaling fixed soon for me because currently I lose fps when enabling SLI. Playing with reduced scaling, less than 4k or dropping everything to crap settings really makes the quality suffer just to get decent fps. 2x2ghz 1080's should run this game much better if it would use more than 55-65% of each card and without negative scaling.

Ok clean install DDU
Found other games capped at 60 verified no vsync. Checked windows settings gamebar recording/full screen optimization... found the issue was with riva tuner I messed with a scan line setting to reduce the overlay flicker and it cause the 60 fps lock. After correcting 100% usage both cards same settings vulkan 50 fps so about 50% scaling.

I have a couple of questions:

- is there a fix for the flickering snow in the opening sequence and while the game is stationed in the snowy area? On sli that is.
- what settings are you guys using when running the game in the 3440x1440 resolution? I’m at ultra on everything and getting major frame rate drops down to the 50s when I’m getting close to the water.
I have turned off msaa, motion blur and reflection msaa.
- and running it on a g-sync monitor.

My setup is 2x2080ti on custom water with a 7940x @ 4.9 ghz and 32gb ram on 4000 MHz.
