Hello @kamikaze211, 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/8004#issuecomment-2308926326.
proton experimentalx1 2024-08
Compatibility Report
System Information
I confirm:
steam-2358720.tar.gz
Symptoms
Specific scene makes game fps extremely low for several seconds, with frame time extremely long, and GPU usage very low.
Reproduction
Attract archers to shoot arrows, then move to the bridge.
You will see the GPU usage will be very low, and the fps will be shown as none, and the frame time will be extremely long.
And I had tried to change another kernel, another Proton version, and updated the system to the latest, and set to the lowest graphic settings in the game.
I also tested on Windows 10, but without this issue.
