Microsoft has long wanted to get vendors out of the kernel. It’s a huge privacy/security/stability risk, and causes major issues like the Crowdstrike outage.
Most of those issues also apply to kernel anti-cheat as well, and it’s likely that Microsoft will also attempt to move anti-cheat vendors out of kernel space. The biggest gaming issues with steamOS/Linux are kernel anti-cheat not working, so this could be huge for having full compatibility of multiplayer games on Linux.
The best anticheat is whitelisting. More coop games, why does it matter if the enemy force is a computer or player? As long as the AI is good enough.
Perhaps*, this is possibly* ok in games with projectile based attacks maybe* but hitscan weapons are not fun to play against when the “player” has no aiming delay.
