Here are my results with the latest patch (2080 NVLink, 3900X, 32GB RAM, trying to play at 4k 60fps with VSync):
 
Flickering of sky, snow, grass, is gone. However, I cannot get this game to be smooth, regardless of the settings. For me, the game is only smooth when I have a large GPU headroom. If my fps without VSync is too close to 60, I will get stutters when enabling VSync. I even tried running at half sync, which my system is more than capable of doing, and the game still stutters some times. If I try to run at normal balanced settings, that means the game will feel like 20fps even though the frame counter says 60, because of very inconsistent frame times. In fact, the game feels smoother (or at least more consistent) when using only one GPU, in DX12. This defeats the entire purpose of multi-gpu... I don't want higher numbers, I want smooth gameplay!
 
Also, the game crashes almost every time I change one of the following settings: Resolution, VSync, triple buffering, TAA, TAA Sharpening, Resolution scale. But only when using Vulkan. I spent like 4 hours yesterday tweaking the settings, mostly because of that...

Are you playing on your main display(focus display in Nvidia control panel)? Asking it coz when I play on focus display (27" QHD) fps are very smooth and I don't feel stuttering BUT when I switch to my 32" 4k monitor I get around 45 fps that feels like 25-30 fps because of stuttering. I have noticed that those stutters feel less when I stare at on my feets rather than stare at distant perspective, maybe it is SLI bandwidth limitations?
That's said, when I switch my focus display to 32" 4k and perform complete system restart those 45-50 fps feel as smooth as it should be.

I haven't tried restarting the PC when switching display configurations though.

You should definitely try it!

Can't believe I'm spending so much time trying to make it work properly.

We are all in the same boat, pal :))))) LOL

I am trying to understand how resolution scale works. Is setting 0.5x when running at 4k rendering at 1080p?

Most probably, yes
 

BlackyMeow
I tried different configurations:
- 4k output with 100% scale: stutters a lot
- 4k output with 50% scale: stutters a little bit
- 1080p output with 100% scale: no stutters
- 1080p output with 200% scale: no stutters

Are you sure those were stuttering? I mean, that might just be "lower than 60 fps" effect while it feels like stuttering. I felt significant difference playing on a primary display vs. secondary display. I had very comfortable 60 fps with 80% render scale on my 4k monitor (remember, after making it focus display and complete system restart), while there were FPS dips here and there I had no stuttering, at least it seemed that way.

Yes I am pretty sure. FPS stays locked at 60. The stutters feel like a huge inconsistency in frame times. Very noticeable when rotating the camera. It really ends up feeling like less than 30 even though the counter stays at 60.

It doesn't happen all the time, it can be smooth 60 for 10 seconds, then stutter for one or two seconds, etc.

Maybe I'll just give up on SLI and 4k60... It's a shame, the game looks really good at native 4k locked 60fps...

I know that feel bro, sometimes you just... *wipes a tear*, you just let it go.
That's why I'm sticking with my QHD monitor for this particular game.

Any of you guys still experience flickering with multiple GPUs on Vulkan when you're in towns where there are buildings? This game is almost perfect now, except for this...

A little bit yeah, but it is intermittent and far less annoying than the sky and water flickering triggered by cutscenes which was prevalent before the April 2 patch.
 
My only real issue now is with the pause menu crash, although the game still does crash at random from time to time.

...when I turn on the MSI afterburner overlay, it is only displayed one every two frames.
 
When the game doesn't stutter, the overlay consistently appears slightly transparent. When the game stutters, the overlay alternates between opaque (like in a normal game) and not appearing at all.

From what you describe, the "transparent" appearance sounds like exactly what you would see if the counter was being displayed every other frame, and the framerate was consistent (and high enough). It's similar to the effect of rotating fan or helicopter blades.
 
On the contrary, if a stutter occurs such that a frame takes significantly longer to render, your eyes would be able to briefly distinguish the counter (or its absence). It would be the same if the framerate were consistent, but say only ~10 fps or less. You would be able to clearly perceive the blinking.

Hello guys,
 
I guess i have a different kind of graphic issue, maybe someone here has a workaround... I followed this post since the release and i don't wanted to play the game until there is properly working SLI which seems most of you got working already. The major flickering most had in the beginning has gone and SLI is working and not even that bad. But now i got a 'new?' problem (screenshots attached). My settings for these pics are all set to maximum except TAA, FXAA and SMAA all disabled. The second screen shows the same settings just with TAA enabled which helped already getting rid of the major flickering before. I tested this on my 3 different monitors and even with just one card, so it doesn't seem to be a SLI depending problem i guess? Does anyone know the bug and got any tips?
 
Specs: I9 9900K 3,6Ghz
32GB 3200Hz
2x 1080TI Asus OC
game running on Samsung 860 evo
 
Hope you guys can understand everything... :D. Please reply if there are any more questions or solutions
 
Greetings!

Hey Sajin! i am unable to import your profile using the instructions given, i get "Profile(s) Could Not Imported!" message. Please help. I am using the latest version of Nvidia Inspector 3.5.0.0 My GPU is Nvidia TITAN X 3way also using latest Nvidia Drivers 445.87

Do i need to downgrade my driver?

Did you run the profile manager as admin?

Yes of course

Hmm, maybe you didn't paste the profile into sli profiles file correctly. If you add to many spaces in the file it won't load it.

445.75.

Works fine for me. I just tested it.

what version of nvidia inspector are you running?

I didn't use inspector. I use the Geforce 3D Profile Manager. There is a 445.75 driver that got removed by nvidia...
