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.
Sure, my comment is directly aimed at a comment stating Valve would basically brick your steam account for this, though. It’s disinformation I’ve seen at too many places this week or oddly enough. While Valve as the CS2 publisher preemptively told players they would unban people once their dlls were normal again.
