crimson desert runs on my Tumbleweed install with a 3060 ti using proton GE.

Consider checking any logs ‘grep “SELinux is preventing” /var/log/audit/audit.log’ and/or journalctl to see if there’s anything obviously stopping it from running. you can also try launching the game through a terminal and see if it says anything.

some random things to try: see if there’s a settings or config file you can play around with.

try some of the proton tweaks on proton.db

try both x11 and Wayland sessions.

if its not installed already you can run ‘zypper in selinux-policy-targeted-gaming’
