Regular crashes related to having only 16 GB of RAM. Managed to workaround by upping zram from 8 GB to 16 GB as well. Like on Windows workaround was to use a bigger pagefile (30 GB).
Since latest update EAC works now.
Performance similar to Windows. On shooting range even more fps but not on the map. Tried different Proton variants and version. No performance difference. Startup video does not show with standard Proton so I stick with GE which fixes this.
Works OOTB
Not working since last update (I guess due to EAC)
After loading the game I automatically get a message displayed saying "cheat detected" and the game closes itself. Sad - it did work before and I even told them on their Discord to enable support for Linux before integrating Easy Anticheat.
