Hello @gbendou, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/8185#issuecomment-3201729811.
Hello @gbendou, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to [#8185 (comment)](https://github.com/ValveSoftware/Proton/issues/8185#issuecomment-3201729811).
I thought that might happen, I wasn't sure whether I should add to that topic given that I had a different issue. Sorry and thank you.
Compatibility Report
System Information
I confirm:
Symptoms
Game worked perfectly on Proton 10.0-1. Once updated to 10.0-2, I began to experience incessant and significant slowdowns and jittering. Hotfix was marginally better, Experimental was about the same. I tried 9.0-4 and the game won’t launch no matter what version I use ever since. Rebooting my computer, verifying the files, deleting the prefix folder and reinstalling the game didn’t help.
Reproduction
Try switching Proton versions, I guess.
