I spent so many hours playing the original KSP on Linux, only to be gravely disappointed by their decision to cut out Linux from KSP2. Has anyone got it working through proton or the like?
I got it working with Lutris shortly after release, can't remember which version of Proton I used. It ran like absolute ass though (despite KSP2 running like ass). Got about 4FPS, whereas Windows got about 15.
