Symptoms

The game's screen easily freezes and overall not playable on my system via Proton 8.0-4 and Proton Experimental. Only Proton 7.0-6 does not have such problem and fully playable. But I also noticed there is some difference in the background of the main screen between 7.0-6 and 8.0-4 (also Experimental). Only 8.0-4 and Experimental have the dynamic background animation.

Reproduction

Just run the game with the specified Proton version.

Proton 7.0-6 (Cannot see the background animation but the game is playable):
game_screen_proton_7
Proton 8.0-4 (Freezes and not playable):
game_screen_proton_8
Proton Experimental (Freezes and not playable):
game_screen_proton_experimental

@darkranger-red Could you try adding this as a launch option? -
"DXVK_MONITOR_FALLBACK=1 %command%"

If that doesn't fix the crashing, could you get a new log with that launch option set and some extra logging channels? You can stack launch options like this:

DXVK_MONITOR_FALLBACK=1 PROTON_LOG=+quartz,+strmbase,+strmbase_qc,+gstreamer,+amstream,+qcap,+qcap_v4l,+qedit,+mciqtz,+mci,+mfplat,+gstreamer,+evr,+dxva2,+wmvcore %command%

Hello,

Yes, I can provide the updated Proton logs. Please see the attached archive. Unfortunately the problem remains via Proton 8.0-4 and Proton Experimental, after the additional "DXVK_MONITOR_FALLBACK=1" being applied.

I am curious about the DXVK_MONITOR_FALLBACK argument. It seems lack of documentation to explain this functionality?

Could you try with only WINEDLLOVERRIDES=winegstreamer=d %command% and see if performance is better? This should disable the background video playback and isolate that from the other possible parameters.

This is just an internal and temporary workaround that we can enable for hand-picked games. It's not documented because we intend to get rid of it.

OK.... after using WINEDLLOVERRIDES=winegstreamer=d %command%, the background video is indeed gone on Proton 8.0-4 and Experimental, so the screen is just as same as 7.0-6. But the performance still freezes unfortunately, and it seems doesn't get any better on my system. I hope this information could be helpful.

Thanks, at least it rules out the video playback from the culprit and it means that it comes from something else. I can see some unusual wineserver load, when that game runs, that might be worth investigating.

I just realized there is something odd between fullscreen and windowed mode. Switched to the latter is actually playable on Proton 8 and Experimental. So I found #7206 and disabled "Force Composition Pipeline" in nvidia-settings. Now the game is fully playable and does not need to fall back to Proton 7. It seems to be the duplicate bug of that issue.
