Linux gaming broken by anti-cheat, compatibility gaps, and UX friction

Gamers who switch to Linux—motivated by Windows 11 frustrations or Steam Deck ownership—repeatedly hit a wall: native anti-cheat systems (Easy Anti-Cheat, BattlEye) crash multiplayer titles outright, non-Steam games require multi-step workarounds with tools like protontricks or Winetricks, and even 'supported' titles suffer 20-30% performance regressions versus Windows. The pain is felt by casual-to-enthusiast PC gamers attempting daily-driver Linux installs; it's not purely technical—it's a UX and ecosystem problem where every edge case demands debugging expertise most users lack. Proton has dramatically improved native Steam library compatibility, but the long tail of launchers (Epic, GOG, Battle.net), MSI-patched games, and kernel-level anti-cheat remain unsolved, forcing users back to Windows or into hours of tinkering with no guarantee of success.
