Developers will be required to disclose if their game uses kernel anti-cheat. This applies to both new games and existing games. Non-kernel anti-cheat is encouraged to be disclosed as well, but it’s only mandatory for developers to declare if they’re using kernel anti-cheat for the time being.
It’s worth mentioning that many games use kernel anti-cheat on windows, but only use user space anti-cheat on Steam Deck and Linux.
FYI - the owner of this site, gamingonlinux, was a mod on the !linux_gaming@lemmy.ml community until they were caught abusing their moderator powers. Then they deleted their account and complained on mastodon that it’s stupid design that mod logs are public. [Screenshot]
