AMD Anti-Lag+ in Counter-Strike 2 can result in VAC ban

Valve has confirmed that when AMD's Radeon Anti-Lag+ feature is used in Counter-Strike 2, it can potentially activate the VAC (Valve Anti-Cheat) bans. This feature, designed for the RX 7000 video cards, modifies the game engine's DLL files, possibly initiating the VAC system's detection mechanism.

The issue seems to be exclusive to Counter-Strike 2, as Anti-Lag+ has been incorporated effectively into various games, including Apex Legends, PUBG: Battlegrounds, and Fortnite, without any hitches. The limited application of Anti-Lag+ technology, restricted only to the Radeon RX 7000 series RDNA 3 graphics cards, reduces its impact on the broader Counter-Strike 2 player base.

AMD's latest driver has made their "Anti-Lag/+" feature available for CS2, which is implemented by detouring engine dll functions. If you are an AMD customer and play CS2, DO NOT ENABLE ANTI-LAG/+; any tampering with CS code will result in a VAC ban.

Valve has recognized the problem and plans to address it post AMD's update. With the recent introduction of Anti-Lag+ compatibility for Counter-Strike 2 in the Adrenalin 23.10.1 driver release, AMD might have retracted the driver in question. This deduction is based on the current unavailability of the driver's download link on AMD's official website and an error message generated when attempting an installation through the Adrenalin software. Valve has reassured the community that any imposed bans will be overturned after AMD provides the necessary update. AMD, however, is yet to issue a formal statement regarding this issue.
