It's almost as if game devs in huge companies can't do things that end users and small game devs can.

It does seem like that. But the reality in most cases is not that they can't, but that they won't. This is what I posted in GTAForums last week, in response to a typical "relax, everything will be fine" post:
 
 
   When you understand that the only reason performance-, gameplay-, and immersion-affecting bugs persist is a lack of concern and not a lack of capability, you understand that relaxing is one of the best ways of ensuring that nothing changes.
 
   No matter how talented and capable employees are of delivering a great game, the handful of people at the top call the shots, and they do not care about video games per se. They are not motivated by passion like the gamer-run studios of the past (or the CDPR of the present), but only by numbers. By money.
 
   I encourage everyone to understand that to an unscrupulous person, or even just a non-gamer, if the numbers are good enough, the game is good enough. And if an executive does not believe that eliminating all significant problems (not all problems, just significant ones) will significantly increase revenue, he has no motivation to do so. I can't stress this enough.
 
   Games have been fixed by fans--without benefit of source code--way too many times for the truth to be doubted even by those who don't understand programming at all. In nearly every case these things can be done--they just aren't.
 
   I know that if Take-Two/Rockstar were to lose all revenue until RDR2 had no significant issues, we would not have long to wait. Not long at all.

Works correctly here with pair of 1080 Ti under Vulkan API with no argument in R* launcher under
Hotfix Nvidia drivers 442.37 i vsync the game at my max framerate 60fps on a 2160p monitor.
i apply a bit OC to both cards to push a bit to 2012 to 2025 Mhz & VRAM +400 Mhz.
Make "pipecache windows" sga files cleans in "W10 documents folder" starting by DX12 reconstruction, then change to Vulkan API. 
Restart game under Vulkan and get back your graphicals settings.
Sometime i see that vulkan is bit buggy like i see "fpsmonitor" with a bit of overlay
clipping (like right after alt tab or something ) and its a sign ;)
i go ingame parameters and switch to "Bordeless" mode (validate) and then return to "Fullscreen" mode (validate) (its like a SWITCH to me) and i see overlay clipping disappear & the game return to smooth (feel it directly when moving your character and camera moving).
i do some test with "asynchronous" compute mode or not but i didn't feel any improvements when activated.
 
Share my graphicals settings if its help.

Are you seeing flickering in the story cutscenes?

New official drivers.

Turn off Triple Buffering.

Spent Days trying to figure this out and now I'm getting a clean 60 - 96 fps on my 1080ti's (x2) I prefer msaax2. taa fxaa all off. Everything else high or Ultra. No flickering lights and background. I do have the Profile fix done in Nvidia Inspector, but that wasn't stopping the flickering, but just reducing the frequency of occurrence. Vsync On 

Monitor resolution?

Turning off triple buffering is not a fix for the flickering unfortunately..

Further, even if it did eliminate flickering, it wouldn't be a fix but a workaround.

New Driver with DLSS 2.0 support

Crashing has gone for me. Played quite a bit over the weekend. FPS seems higher also and framerates feel better

Without HDR. I don't have a HDR enabled monitor :(

The April 2nd patch--very surprisingly--mentioned multiple SLI-specific fixes related to both performance/stability and graphical bugs. Can anyone determine whether the patch delivers a real, substantial difference for performance and visuals? Basically, whether it makes SLI a legitimate option without significant drawbacks?

Hi great Cowboys,
 
Playin a bit online today after consulting the tread here ;)
(1 month i didn't play RDR2)
2nd April patch (patch note with fixs for mgpu tech) installed and activated Mgpu under Vulkan API with NV 445.75 drivers, keepin the same graphicals settings posted with a bit NV driver included "sharpening" till my last post and ?
Nothing consitant at all !
Maybe some visual glitches solved but to be honnest i didn't see anythings going better or less...
Always be oblige to use "parameter switch" borderless to Fullscreen mode to try to ramdomely "synchronize" Multigpu loading values to try to stabilize things.
game leaves me with this impression that "volumetric fog" is visualy not good as before and game tank more FPS.
SO really nothing new under the sun from my point of view.
 
Next big thing will be maybe when Vulkan 1.2 will be add in next drivers, ( hope soon)  when they finished tests in another driver branch.

DLSS 2.0 is not implemented in RDR2 AFAIK. Can someone else confirm?

Correct.

So what is the final verdict right now for running this in SLI with 2x 1080TIs? Ive been trying to read back through but I'm not really seeing anything definitive. I've been running single GPU in DX12 for a while now, it's been relatively smooth but FPS obviously ins't that great. 4K with certain settings backed down to smooth it out. should I even mess with SLI?

I usually get frame rates in the high 40s but it’s smooth and consistent. No artifacts or stuttering or anything weird so it’s definitely playable. Saint Denis at night hits a little harder, especially with driver updates in the past couple months. I’ll post up settings and specs when I can tomorrow.

I tried messing around with SLI back in Nov/Dec but it was just never consistent. Even if it worked and I was getting more frames, the game wasn’t ‘playable’. It didn’t feel smooth. So I said screw it, I don’t have the time anymore to try and make this BS work right. I was spending more time on that than actually playing the game.
