i'm using the default profile now as recommended by sajin.
not overclocked I get the "ERR_GFX_STATE" error. and that's with everything on ultra + vsync (except reflection on high and water stuff on med)
 
:(
 

For people getting the "ERR_GFX_STATE" error try underclocking your gpu's using msi afterburner. Set core & memory clock to max negative values for testing. The only time I've had the "ERR_GFX_STATE" error was when my graphics cards were overclocked too high, and were unstable.

The game is now PERFECT IMO - MGPU works, no flickering, and really fun to play!
 
Getting ~ 80fps in 4K (all Ultra, TAA "Medium").
 

G-sync on? And triple buffering and vsync off in the game menu?

 
I'm not using a G-Sync monitor - it's the Alienware AW5520QF (55" 4K OLED 120Hz monitor). I do have triple buffering ON in the game menu (no V-Sync).

my friend, what GPUs do you have?
I've got2 2080tis stix and all cracked up settings will dip below 60

I'm using 2x Titan RTX in SLI/NVLink.

Running 9900k with 1080ti SLI. Running vulkan @ 1440p with mostly high settings and i m getting horrible MSI AB flickering and awful frame pacing. Gsync on or off makes no difference. 441.20 drivers with default profile.
 
Plz any help would be appreciated.

MSI AB OSD flickering is due to Vulkan MGPU and has nothing to do with this game. Try Strange Brigade with MGPU on Vulkan and watch it do the same. The creator of MSI AB says he won't be fixing this in the near future so that's that.

ok so i uninstalled the game.. done 3d mark score is ok'esh.
then installed RDR2 now the "ERR_GFX_STATE" is gone

Triple buffering is only meant to help increase performance when v-sync is enabled. I wouldn't use triple buffering with v-sync though as it adds more input lag.

cool didn't know that!

So I have the latest drivers but if I run the game with Vulkan w/ SLI enabled in the control panel, I get a black screen regardless of settings when I either go to benchmark or enter the game, actual rendered areas.  I have to force quit the game.  If I disable SLI and use Vulkan, it will work.  DX12 will work regardless of SLI settings.  Any ideas what could be causing this?  Was excited to see what kind of performance gains I was going to get.  I have a pair of 2080TI FTW Hybrids, i9-9900k.

So at this point it's fair to say, with latest Nvidia drivers(441.20) and RDR2 patch 1.14, we're likely looking at another patch or driver set if we're lucky, before we're at 100%?

I would say so.
 

   Greetings to my MAXWELL brethren! I thought I would share my exact step by step getting SLi to work, SPECIFICALLY WITH GTX 980ti. If you have a non-ti 980, remember to play it safe with the 4GB you have for texture load. 
 
   My GPU memory used with these settings is, if I recall, 3.3 GB (sorry at work!). I, like many, avoided updating my driver to the latest because I heard terrible things. So first, I updated Windows to the newest update. Finally after bashing my head against concrete and having the fun "bridge active, 2nd GPU engaged and fans spin up, bridge lights flicker off and on, fans spin down, eat ****, rinse repeat", I updated that driver. I have everything in my computer at ALL STOCK, NO OVERCLOCK. Running 4770K, 32GB Ram, and two 980ti Superclocked, and against my judgement, I updated from 441.12 by doing the "clean installation" through nVidia's driver installation via GeForce Experience, I didn't wipe my drivers with DDU* (Before I installed 441.12, I used DDU to get rid of the previous drivers that I had from like a year ago. Also, I did not change any default values thru NV Inspector either at all beforehand, just to clarify).
 
  First I updated the drivers, then I updated the game. I don't know if it matters, but I have an unfounded conspiracy theory that the game runs better in SLi with "VSYNC to (Smooth)". Everything else in NVCP is "high performance" or "max power" but I turned everything else "off". Also make sure SLi wasn't switched off after the driver update. In-game, like so many have stated, only works with Vulkan API and TAA must be ON. I get judder if I don't use VSYNC and triple buffering in game, so I use that as well. We wont be doing a lot of 4k my dudes and dudettes (or any at all), but at 1080p you should be able to run most settings at High/Ultra @ 60 fps. I average 67 fps in the in game benchmark, and I have had drops to 50 in game, like in spooky foggy forests with light breaking thru. I don't have a GSYNC display so I cannot comment on anything relating to it, sorry. When I have VSYNC enabled, I have an average of 59.97fps in the game benchmark. There needs to be more pedestrians in the Saint Denis part of it, because I get a rock solid 60 during that and I know I shouldn't be. Both cards usually around 95% utilization.
   
   Before I forget, I should mention that resolution scaling is buggy and will blind you with the light of a million suns, so if you are wanting to downscale to 1080p or whatever, set the resolution to that in the game. It is unfortunate, but what can you do?
 
Here are THE SETTINGS I DO NOT HAVE ON ULTRA from the top down in the options:
 
+Screen Space Ambient Occlusion: High/Ultra
+Reflection Quality: Low/Medium
+Water Quality: Custom*
+Volumetrics Quality: Custom**
+TAA: Medium
+FXAA: Off
+MSAA: Off, lol
 
+Unlock Advanced Settings
+Graphics API: Vulkan
**Near Volumetric Resolution: Low
**Volumetric Lighting Quality: Medium/High
- Unlocked Volumetric Raymarch Resolution: Off
- Full Screen Space Ambient Occlusion: Off
*Water Reflection Quality: Medium
*Water Physics Quality: 50%, preferably less (I usually have it off just for some more gains)
-TAA Shapening: Your Preference
-Motion Blur: Your Preference
-(New)Tree Tesselation: I perceived no decreased performance with this on, but as you all know, mileage may vary. (By vast oceans it would seem for a lot of us )
 
In closing, I am impressed. It seems that if you are getting bad performance at low settings, try turning the dial to 11 and working down. The game runs worse for me on low by a good 10-15 fps. I guess saturate that GDDR3 with pretty things until your gpus are begging for a bullet. I really hope more of you guys get SLi working soon. First post here, sorry for the formatting. I will try to update this post with screenshots and possibly a video. Focus a webcam PiP view of my physical cards and letting everyone hear them cry while watching the glory of the game. I have never tasted tears so sweet @ 80C.
 
Cheers and best of luck.
 
TL;DR:
 
1.) Update Windows to the newest version (Unsure if this has any bearing, but I am including it because I did so before getting SLi to work) 
 
*I DID NOT modify any value from default in nVidia Inspector*
 
2.) Use DDU and then do a fresh install of ver. 441.12 (previous driver)
3.) Update through GeForce Experience to ver 441.20 (Clean Installation Option) *DO NOT UNINSTALL 441.12, UPDATE TO 441.20 ONLY. Remember to turn SLi back on if it was disabled in update.

4.) Update RDR2 to new patch
5.) Turn all options possible to High Performance / Max Power in nVidia Control Panel
6.) Turn off all other options in nVidia Control Panel
7.) Turn on VSYNC (Smooth)
8.) Launch game. See above settings used in game.

MGPU is only going to work using Vulkan.
 
You can  take a look at the optimized settings here and that should give you a nice base line performance to work with.

well, I was talking about Vulkan and no, why would I lower my settings to use mgpu when I'm already having better results running one one card, everything maxed out. It doesn't make sense and is a no-go.

So with latest drivers & game patch, SLI is now functioning properly? without the use of custom profiles?

Yes, but there is still some flickering here and there.

Do you get FPS drops near the water? I get drops to the 40s and 50s near the water - it's super annoying and breaks the smoothness of gameplay. Most other areas are 70s - 80s+ FPS which is buttery smooth.

Yes.

not overclocked I get the "ERR_GFX_STATE" error. and that's with everything on ultra + vsync (except reflection on high and water stuff on med)
 
:(
 

 
I ran into this issue as well during my testing last night. Trying restoring default settings. That was the only way I could get it to work again. You can then make adjustments from there.

 
 
Error ERR_GFX_STATE
This error began to appear among players after the update of November 13. In Documents \ Rockstar Games \ Red Dead Redemption 2 \ Settings, delete all files starting with "sga_". After that, load the old save, go to a new location and make a new save there.

If you guys are getting the GFX crash, go in to your settings folder and delete the sga files. This cleared it up for me.

After a few days of trying to figure this out, I am still having a weird issue with Vulkan and multi-GPU and the game.  If I go into any in-game areas or benchmark, I get a black screen and audio plays for a sec and then stops, the game locks.  I can alt-tab out and get it to "Stop responding" and force quit.  DX12 works fine, Vulkan will work if I disable SLI.  Seems like I'm the only person experiencing this.  Worked fine before the patch (albeit not running in Multi-GPU).  Steps taken to try and fix: DDU uninstall of drivers, reinstall clean 441.12 and 441.20.  Went safe mode graphics, even 720p in a window it still does the same thing.  Menus all work fine, just anything where it goes to the in-game engine.
 
Has anyone else experienced this?  I'm running dual 2080TI's.

That did it!  Thanks so much.  I've been digging through this thread but I guess I just missed that.  Thanks again to everyone who puts in the work to figure out all this stuff.
