Far Cry 1 DXVK 2.5 (and 2.5.1 too) regression with glitches on terrain/objects reflections in water
(I'm taking this as an opportunity to also say that, the Nvidia CPU performance reduction thing is indeed an Nvidia driver issue, as AMD cards don't have this problem at all, and shows the expected CPU performance improvements, 80 FPS native vs 95 FPS translated on a specific spot)
~Are we talking about the original Far Cry here or the remaster?~ Nevermind, I misremembered there being a remaster. Filling in the issue template would be nice, and also attaching at least a screenshot of the problem.
Reflections look the same to me on master vs 2.4.1, see below:
2.4.1
Latest master
So you'll have to be a bit more specific regarding what the regression is.
it's more of an animation issue, some frames of the water reflection animation look glitchy since 2.5, I have MSAA enabled (in game, clean dxvk.conf), I would need to record a video to show it to you, would that be of interest to you?
As for the form I'm not sure it would be very informative, I'm on latest everything that is not release candidate, on W10.
I also see that you're on an Nvidia GPU, so that may be an AMD specific issue :/

No need, @Blisto91 was able to reproduce it.

Yes, it appears to be an amdvlk/proprietary issue in particular, as it can't be reproduced on Nvidia (proprietary or nvk), nor on AMD radv.
I did the video anyway in the meantime :D next time I'll do that first I guess, I have to stop assuming all GPU brands are the same in terms of drivers!
Bisected to start with commit https://github.com/doitsujin/dxvk/commit/b4ed1081058be5361784f686aa07b194057dd8a6
I only reproduce with amdvlk (open. Pro untested) and not radv, Nvidia or nvk
Edit: Apitrace: https://drive.proton.me/urls/3HSHZJ278C#nnUKWQBKiLbD
Only happens with 32bit replay. 64bit is fine.
Made a amdvlk issue https://github.com/GPUOpen-Drivers/AMDVLK/issues/386
Any fix there will very likely carry over to Windows.
This seems to have received a double fix. With dxvk i can no longer reproduce the issue since commit https://github.com/doitsujin/dxvk/commit/90ee5fe18021486fc4e61bc168f63bb21642a882. With Linux amdvlk the issue is also fixed in 2025.Q2.1.
Nothing extracted yet.
DXVK 2.4.1 is the latest version where it worked fine.
Tested on Windows 10, AMD RX 6800, latest drivers (24.12.1)
The presence of the Silent Patch doesn't make a difference (just in case).
Clean or modified dxvk.conf is the same as well.
The game has native MSAA enabled (x4), in case that can make a difference.
