Anti-cheat software

Anti-cheat software is software designed prevent cheating in videogames. Typically, client-side anticheat prevents games from running on Linux.

VAC natively supports Linux. Moreover, the anti-cheats EasyAntiCheat and BattleEye currently have support for Linux through Proton. This has resulted in some games enabling this Linux support.

Details of anti-cheat support

EasyAntiCheat

EasyAntiCheat became supported in a recent Epic Games EasyAntiCheat SDK. Since many EasyAntiCheat games don't use this SDK, many games must update or change out their anticheat SDK for the ability to enable Proton support.

BattleEye

Developers can enable Proton support for their game by emailing BattleEye developers.
