If you are running linux do not buy. You'll have somewhere between 5-30fps usually. On launch from what I can see both windows and linux versions suffered. Windows version was fixed but linux version sill has same problems as on launch. It's ridiculous that 3800X and 5700XT give only 20fps on average. (played during steam free weekend)
Needs optimisation. GPU is 100% even on hand drawn cut scenes.. Feels almost like they are cryptomining. Otherwise feels like decent game so far.
