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.
You will never stop cheaters, ever. It’s something we have to live with. It’s annoying when it happens, but it’s hardly the end of the world either.
So I’d rather have the AC running on the server and not invading my system.
