Issues

• I haven't experienced any issues.
• There are no issues left open for this game.
• Although I consider the gaming experience equal to Windows there are remaining issues:

• The game works pretty well with the controller (Xbox) not configured in steam. I also tried the community part and it was also working.

• There is a little bug when you launch the game it cannot go in fullscreen directly.
  You need to go to the options and switch it to windowed appy, fullscreen apply (maybe it's only on my laptop).

• The sound looks like crackling sometimes, it's not very big but I think it can be annoying in long play

• Same with 720p and all options at low i'm at 30/35 fps and 40/50 fps in the menu. It not look laggy, but it's maybe related to my hardware

• When I quit the game I had this error

Start with the reported Shift Quantum behavior in this issue, including the fullscreen workaround, intermittent crackling, performance observations, and quit-time error screenshot. Review the linked system information report and the Proton 3.16 Beta context; done would require identifying a reproducible compatibility problem and defining a verified fix or diagnosis.
