AMD pulls graphics driver after “Anti-Lag+” triggers Counter-Strike 2 bans

AMD has taken down the latest version of its AMD Adrenalin Edition graphics driver after Counter-Strike 2-maker Valve warned that players using its Anti-Lag+ technology would result in a ban under Valve's anti-cheat rules.

AMD first introduced regular Anti-Lag mitigation in its drivers back in 2019, limiting input lag by reducing the amount of queued CPU work when the processor was getting too far ahead of the GPU frame processing. But the newer Anti-Lag+ system—which was first rolled out for a handful of games last month—updates this system by "applying frame alignment within the game code itself," according to AMD. That method leads to additional lag reduction of up to 10 ms, according to AMD's data.

That additional lag reduction could offer players a bit of a competitive advantage in these games (with the usual arguments about whether that advantage is "unfair" or not). But it's Anti-Lag+'s particular method of altering the "game code itself" that sets off warning bells for the Valve Anti-Cheat (VAC) system. After AMD added Anti-Lag+ support for Counter-Strike 2 in a version 23.10.1 update last week, VAC started issuing bans to unsuspecting AMD users that activated the feature.
