Proton is like magic. I remember when gaming on Linux only worked for some rather old games. Now you can almost buy anything from Steam and expect it to work on Linux. What surprised me the most was that even Enderal, an excellent total conversion mod for Skyrim, just worked. The same goes for the newest Hitman. I expected that I have to do some tinkering, but no. You click play and that is it. I doubt that any of these games where ever tested on Linux by their developers. That they all work so well shows how good of a job the developers of Proton, DXVK, and Wine are doing.
