"work" it's a lie, they don't work like they do on windows.

- performance can be really bad

- lot of bugs that you don't have on windows

- the usual go tweak this cfg file and try this

Look at that for example, what they consider working "gold": https://www.protondb.com/app/275850

I do agree that the performances are no the same than on Windows (15-20% less FPS on average).

I don't know about the official proton for No Man's Sky, but I used the Glorious Eggroll's fork[0].
