Looks like this game might keep the DXVK/Proton/Driver devs awake for quite some time. So many new techniques crammed into a single game that's also quite demanding on all components once you go above medium settings.

I’m 50% through it on Linux. It runs great but ever since the last patch after I’ve been playing for about an hour my framerate tanks to the low 30s until I restart the game.

Also the they’ve enable raytracing on AMD GPU’s but it still isn’t enabled on Linux.

Damn thought that was a sick Ratchet & pun
