Easy Anti-Cheat now supports all major PC operating systems, including Linux, Mac, and Steam Deck.
One of the Steam Deck’s biggest hurdles just disappeared: EAC has come to Linux and BattlEye is inbound
Update: BattlEye is coming too
kudos to Epic for making this happen when they clearly didn't have to and it seems BattlEye is doing the same coming up pretty soon, expect Proton and Steam Deck compatibility with games to be in the high 90 percentages as these two anti cheat systems seem to have been the biggest issue effecting Proton.
the support is not automatic tho and has to be implementing by every developer themselves but i'm sure all of the high profile games will implement support pretty soon.
