The other day Valve announced a problem with the automatic imposition of VAC bans on Counter-Strike 2 players, supposedly due to cheating, but in reality related to the AMD Anti-Lag+ feature and the modification of one of the DLL files. After that, gaming fans began to actively report other similar incidents – other online games were also affected, notably Call of Duty and Apex Legends.
In response to the constantly improving cheating methods, which are mainly expressed in interference with the game’s graphics engine, developers need to implement stricter measures – tools for general detection of anomalies in all game files. This is especially true for multiplayer games, where the activities of cheaters cause significant discomfort among the entire community. For this reason, the VAC (Valve Anti-Cheat) system has started banning users who have enabled the AMD Anti-Lag+ feature in Counter-Strike 2 – it modifies the game’s DLL file, which the system calls attempted fraud.
According to AMD, the only solution to the problem so far is to disable this function. And for those who have already received a VAC ban because of this, she promised an amnesty for the future. Players began reporting more frequent crashes in Call of Duty: Modern Warfare 2 and Warzone 2.0 – when AMD Anti-Lag+ was enabled, games began to crash, usually when starting multiplayer modes; and also in Apex Legends – account bans are practiced here, even if the account has been inactive for several months. A similar feature, NVIDIA Reflex, does not cause such problems – it is not implemented at the driver level, but comes as a separate library that game developers add individually. It’s worth noting that Anti-Lag+ is only supported by AMD Radeon RX 7000 graphics cards, so owners of previous generation models are not affected by the issue.
