Some games anticheat supports Linux. VAC, EAC, GameGuard, and BattlEye either run under Linux by default or can be configured to do so, by the game dev, with a toggle. A number: Destiny 2, Fortnight, etc. break it intentionally even though the client could run without modification. Battlefield 6 breaks because it checks the Windows measured boot API.
