> So they either ignore Linux/Proton altogether or have to start actually implementing anti-cheat for a Linux/Proton environment. Most of the popular anti cheats do work on Proton. EAC, Punkbuster, Battleye, and VAC all work fine, which I think covers most games with anti cheat. Unfortunately some of those require opt-in by the developer to work on Proton, and therefore some developers have neglected to opt in. A handful of other games use their own anti cheat that does not work, and unfortunately those games have the resources to do that because they are very popular (CoD, Valorant).
