Kernel-level anti-cheat feels like it's everywhere now, and will remain a thorn in Valve's side for the new Steam Machine powered by SteamOS Linux.
On Linux, there's no kernel-level mode available for anti-cheats like they would use on Windows. I know plenty of readers, and gamers across the net probably see it as a benefit due to privacy concerns, and that's fine - but it doesn't change what a lot of people want to play that can't.
This is something many bigger games simply don't want to pull away from including the likes of Call of Duty, Vanguard from Riot, EA Javelin for Battlefield and so on. While we do have some anti-cheat vendors that support Linux like Easy Anti-Cheat and BattlEye (and a few others), it's user-mode with no kernel-level and many developers really don't like that.
Cheaters ruin games. Anti-cheat sucks for privacy, and is ineffective to a point. As long as there are tryhards willing to shell out a few $ to have a leg up on the opposition, there will always be someone willing to code a way to make it happen. Even statistic-based anti-cheat is an utter failure. Not sure what the answer is.
You just have to make it expensive / hard enough to cheat that most people don't bother.
I understand peoples distrust in kernel level anti-cheats and why they suck, that being said, back when I still played multiplayer games Valorant (that has a kernel level anti cheat) was so much ahead of CSGO that it was not even a comparison. I don't know whether it was due to CSGO's anti cheat being bad or Valorants being good.
When you have to spend 50 eur / month to cheat most people don't and that's good enough for the casual player base. Not sure what the case now is with CS2 and other online games in general.
