Removing 3rd party kernel access will probably also make cheating harder. Kernel anticheat is necessary largely in part due to cheat software using exploits in the 3rd party extension system to get kernel privileges itself and evade user mode anticheat.
Yeah this tracks, I don’t understand why people recommend Debian so much, especially to new users. Distros that update more regularly like Mint or Fedora (for non nvidia users) are much better options.
