Recently there was a thing where VAC would erroneously flag AMD’s antilag+ feature as cheating, and issue a ban.
AMD then quickly disabled the feature by default but now Valve also patched detection for it and is now, at least according to these patch notes, reversing the bans.
it’s really not amds job to know how anti cheat works I’m gonna be honest most software devs probably could give a rats ass how it works the software devs probably were just like this works and isn’t causing crashes ship it
