Hello @Rowtha, 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/6638#issuecomment-4809855135.
hey kisak-valve, ive checked the new one and i have not seen any duplicates.
i have tested 10.0 and 9.0 Beta, experimental, hotfix,11.0 (beta) and nothing is working, the game (modded) just does a no signal thing (unity does that when a video cannot be decoded) because the game uses the windows video thing, heres some screenshots
