they added some nice tools though. e.g. their pacdiff & meld tool eos-pacdiff is pretty nice. then there is a kernel manager and a pretty clever update-script / wrapper around pacman and yay (eos-update). saying it is just Arch + GUI is selling it a bit short imho.

Cheats running at ring0 aren’t invisible

Every rootkit ever disagrees with that statement.

They can actually invest in server-side detection

I’m not deep enough in the topic to be able to judge this, but i would guess the needed extra hardware is simple not worth it. especially in games with many players or complex physics i would guess that could lead to considerable load on the servers.

Plus, server side is not able to catch things the client manipulates on his side. e.g. graphical data to make walls transparent. The server could at most catch the player abusing this knowledge, but if he is smart about it, the server has no way to ever notice.

it’s possible to make a good AC without fucking around in the kernel.

What if the cheat runs in the kernel? I am also against these extremely invasive anti-cheat measures, but it must be clear to everyone that the cheat developers and users have no qualms about this.

A user level AC can do shit all against that if the cheat runs in ring 0.
