Crashes when starting a game. -force-d3d11 to fix.

Works great. Performance is good. Had one crash/freeze at the beginning. No more problems so far.
One freeze at the beginning. No more so far.
Feedback is based on the demo playable in August 2025

If running older hardware and error message "SuspendThread loop failed" Then force dx11 to allow game play. But it reduces the games beauty

Stutter during initial video cutscene play
Dark gamma basically
Video playback had stuttering, this is due to my old hardware though.
If you have modern hardware then the launch option is not needed most likely, when running proton experimental.
