Hello @vulturm, 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/4125#issuecomment-1047268177.
Hello,
I haven't added it to the other bug report because I considered that this
one is related to performance regression and the other issue is related to
compatibility/game isn't starting/is crashing.. and there are already lots
of post there and it might get lost.
But, if you consider is better that way, then thank you!
