I’ve used to be able to play this game just fine at around medium graphic settings through Proton (GE), but today when I launched it again after a while the performance was just really poor.

Like mouse-moves-at-30fps-in-the-menu-poor.

There have been plenty of package upgrades since my last launch including plasma 6, proton and the game itself. So I don’t really have any particular suspects here.

Running Arch with AMD GPU. Wayland/Xorg didn’t seem to make a difference.

Has anyone else experienced similar performance degrading in this or another game lately?
