FPS Drop in Dying Light with DXVK 2.5.3

[v3kt0r-87]

I have encountered a significant FPS drop when using the latest versions of DXVK (2.5.2 and 2.5.3) in Dying Light 1 and its DLCs . In contrast, using Proton 8.0.5, which includes DXVK 2.3 , the FPS remains stable at 60FPS. A video has been uploaded showing the gameplay with both versions of DXVK for a clearer demonstration of the issue.

Hi there and thank you for the issue.
Is the dxvk 2.5.2 and 2.5.3 test done with what comes with newer Proton versions or have you manually switched them around? I'm curious if helps Proton 9 or Experimental to use a older version or if it stays the same

[v3kt0r-87]

No I haven't manually switched dxvk version

I only changed proton version , first i tried proton 9.0.3 then 9.0.4 and then latest proton 9 experimental - bleeding edge

Then I remembered that back in 2.3 dxvk I wasn't facing any issues and I was using proton 8 , so switched back to proton 8.0.5 and fps issue was fixed

Just played the game for about 3 hours with latest master and it was fine. It's most likely an issue with Proton, as I'm on Wine Staging, and not something dxvk specific.

[v3kt0r-87]

Well this problem is on all stable version of proton 9
( i tested this on 9.0.3 and 9.0.4 )

Only proton version that's working is 8.0.5d with 2.3 dxvk

I will try to manually swap dxvk to 2.3 in proton exp and report back

I've tried for a while to reproduce the issue on either my Arc b580 or my AMD rdna2 iGPU. But have been unable to

Update :

manually swapping dxvk version from 2.5.3 to 2.3.0 in proton experimental fixed all stuttering and fps drops

i uploaded another video

also uploaded new proton logs :

i will try to manually swap dxvk version to 2.4 and test again until i can find out which dxvk version causes fps drops and stuttering

[v3kt0r-87]

DXVK 2.4.1 works without any issues , also uploaded new video and proton logs

Does it change anything if you run the game with DXVK_CONFIG="dxvk.enableMemoryDefrag = False"

[v3kt0r-87]

nope here are the logs :

from dxvk 2.5 onwards this happens , gonna stick to 2.4.1 with proton 9.0.4 as it fixes my issue for now
