@gamingonlinux I started an experiment of being Linux-only late last year as a result of how far Proton has come, and I haven't needed to boot up Windows at all since (though I have done to play around with libvirt and such).
The only thing that I miss doing is modding for A Hat in Time, since while I *can* get into its UE3 with protontricks tweaks, the performance was not great the last I tried. Might give it a go again now I'm all AMD.
