Proton has been fantastic for me, it finally gave me what I needed to reclaim my Windows partition and go full-on Arch! In some cases, running the Windows version inside Proton has actually worked out better for me than the native port (Dead Cells, for example.

I wasted a lot of time with DXVK when I tried to play Tomb Raider 4. WineHQ said you need DXVK when you want proper shadowing, but I could not get it to work.
