Infrequent slow downs
After launching with Proton-5.0-9, a Unity logo is displayed briefly, followed by a black screen. You can still hear the sound of the Apogee logo in the background but the game doesn't run. I was able to start it successfully on my system with Proton-5.9-GE-7-ST.
The game runs natively on Linux since 2020-11-06.
You have to move your savegames.

I played the game with frequent crashes up to about level 15. No Steam launch options seemed to help, I tried them all. Switch the Kernel!

FSR problems with dark textures.
Starts in window mode every time.
Capcom has an incomprehensibly stingy attitude towards savegames in this game, even after the patches.
Frequent and unexpected frame rate drops in various regions of the game.
Frequent crashes before I switched to kernel version 6.7+.
Error GCVM_L2_PROTECTION_FAULT_STATUS occurs when an AMDGPU and Linux kernel version up to 6.6 is used.
I finally found the problem in the systemd log using journalctl: GCVM_L2_PROTECTION_FAULT_STATUS. I switched from Linux kernel version 6.6 LTS to 6.7. After that the game did not crash on my system anymore.
Short version: Switch to linux kernel version 6.7 and higher!
