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.
No problem.

this is what I am getting after new drivers: DX12 with or without SLI: same performance Vulkan with SLI enabled: VERY bad performance Vulkan without SLI enabled: same as DX12 with or without SLI So for me SLI makes the game runs even worse ....  1080 Ti FTW3 SLI / 9900k / Z390 Dark. I am not playing the game unless they fix this mess with SLI.

You're not alone, mate. Our 1080Ti's clearly have issues with SLI in this game. Vulkan or DX12 on single gpu- well, okay, it works. mgpu Vulkan- as you said VERY bad performance unless you disable TAA ingame (then, in my case, at least, both cards go to 90% usage but the overexposure makes it unplayable).

Nice thread to read. Seems its very hit and miss where mGPU works for RDR2. I have an opportunity to get another EVGA 2080Ti. But the only game that needs it really is RDR2. I play at 3440x1440 with GSYNC.
I may purchase it and test it

Ditto. From what I've gathered talking to friends and associates, all of my circle that are using 20 series cards have SLI working fine now. All of us with 10 series cards are getting pretty much what you're describing. No scaling with SLI, identical avg fps to single card avg fps but with terrible frametimes that don't present in single card modes. Also using 1080 Ti FTW3 SLI

I run the game with 2080ti sli w/441.20+vulkcan but still got terrible frametimes even though the fps is double to the single card and usage of both card is above 95%...it's wired and there must be something wrong with the profile given by Nvidia or Rockstar~~

Also using 1080 Ti FTW3 and it's the same scenario. But for me the odd factor is G-sync. (see my previous posts.)

That's been one of the oddest things about this for me. I'm used to seeing games with low/no scaling also have low or uneven usage on the GPUs which makes sense. For this one, in single card or SLI the usage stays in the 97+ range regardless, but the average fps remains the same. The only difference is that frame time graph for SLI looks like someone tried to draw a straight line while driving on gravel with a flat tire.

Are you guys still experiencing flickering in the initial snow chapter? I’m still seeing very annoying flickering during cutscenes in this section of the game.

I disabled Gsync for RDR2 via gameprofile to fixed refresh rate. The game is much smoother on vulkan even with a single card when Gsync is disabled I did a ddu install for the 441.20, deleted the settings folder after the last patch and checked the gamefiles with the launcher. My FPS are ~15-20 higher than with a single card, but horrible frametimes, vsync on/off makes no difference.

Well,the game actually runs smooth while fps is above 60fps but the stutter and paceing will come if the fps is under 60fps,i have returned to single card untill Nvidia or rock star fix the sli~~

Can you tell me if you do anything specific in Nvidia Inspector or NVCP?

Yes, they have been doing that for more than 2 years now. Thats why they also want sli gone and why they will never fix sli issues here. Who would buy a 2080ti if two 1080s in sli beat it? Be careful when making those comments tho, thread is full of nvidia fanboys.

At the rate at which they are fixing SLI bugs with the latest updates (to both RDR2 and the nVidia driver) I would imagine the remaining issues will be disappearing in a couple weeks.
Right now things work well for me (two 1070 boards) with the latest (.20) driver, but you can't turn off TAA without making the game unplayable. Since TAA kills SLI performance, once this remaining problem goes away we'll be in pretty good shape.

Indeed. But it is not only the 10 series. It is every gpu below the 20 series. And it has been happening for about 3 years now, (slowly getting worse). My Maxwell GTX TX SLI setup suffers from the same thing you 1080 peoples are talking about. Would love SLI to be working so my 1440p would run smoother and prettier. But alas, stuck on a single GPU with mixed Ultra-Med-Low settings to stay between 45 and 60 fps.... I keep seeing people say they are dropping SLI because there aren't many people using it. Weird thing is, Everyone I know IRL runs a SLI setup and I see many people online that apparently use it, so I think that argument is moot. I personally feel Nvidia is actively working against consumers like me that will purchase a nice set of GPUs, OC the Shiz out of them and have them last 4-5 years before selling them off and buying a new setup. They want yearly purchases, so they make sure to keep a step behind the demands of current games and then gimp SLI for people not running the latest greatest build. A real turn off in my opinion. Lets hope 2020 shows some actual competition on the GPU front so us consumers might actually win a little... ring0r

heard that gimp thing was a rumor already dismantled..several times! BUT... but.. i definitely believe they do it. lets not be naive! they are a company and bottom line: companies want profit and for that they need to sell their new stuff year after year to maintain the profit margins... and for that to happen at that rate they need to cripple old stuff so people are pushed to justify and purchase new gpu's! its simple logic! altho... despite that gimp rumor allegedly being dismantled over and over according to some other forums ... so maybe its still somewhat debatable... one thing for sure.. my "new" 1080 Ti costed my a LOT AND will last until 2023 AT LEAST. i don't care about anything else. either way the gpu market core is around the XX60's and xx70's series.. cause not many can buy the xx80's and Ti's versions...

Try going into the settings folder and deleting the sga files. Any time I have gotten this error, deleting those files has cleared it up for me.

Installed the hotfix driver, ran Red Dead. Same issue, no scaling. Disabled gsync (despite this doing nothing with previous drivers), got some scaling. Benchmark runs went from consistent 70fps to consistent 80fps. Not amazing scaling, but something is better than the nothing I had before.
Also worth mentioning, Fallen Order seems to have similar odd behavior. gsync and SLI = no scaling. Turn gsync off, get scaling. I remember SLI and gsync having issues working together ages ago but it was resolved, I wonder why this issue seems to be popping up again.
