Getting 30-40 fps on a modern system. It’s using ~30% of all CPUs but little to no GPU (although nvtop says it is using vram). It feels like it must be doing software rendering or something… Tried both linux native and proton versions. Does anyone here have any idea how to make it perform better?
Edit: It just started working fine on the linux version.
On that page I have found only one report matching your description and that was four years ago. I am guessing whatever is going on must be an Nvidia quirk.
