Valve has issued a warning about the Anti-Lag and Anti-Lag+ features present in AMD Radeon GPUs, as they could potentially impact the anti-cheat system of Counter-Strike 2 and result in players getting banned. The Anti-Lag feature has been in use since the Radeon Polaris era and controls the CPU’s work rhythm to prevent it from surpassing the GPU, leading to reduced latency and improved response time in games. On the other hand, the recently introduced Anti-Lag+ feature in the RDNA 3 GPUs (Radeon RX 7000) takes it a step further by synchronizing frame rates for individual games.
The problem arises when Anti-Lag+ interacts with the game’s DLL files, causing the CS2 anti-cheat system to perceive it as an attempt to cheat, similar to various cheating programs. Consequently, Valve’s Anti-Cheat System Ban (VAC Ban) comes into play, resulting in the suspension of a number of players.
Acknowledging this issue, AMD has stated that they are aware of the problem and are currently working with Valve to address it. In the meantime, they advise CS2 players to disable the Anti-Lag+ feature while playing the game.
It is worth noting that AMD is one of the partners involved in the launch and promotion of CS2, claiming the use of the Anti-Lag+ feature to reduce game latency. However, it seems that the interaction between AMD’s feature and Valve’s anti-cheat system was not previously discussed, causing them to not work together effectively.
TLDR: Valve has warned that using AMD Radeon’s Anti-Lag and Anti-Lag+ features in Counter-Strike 2 may trigger the game’s anti-cheat system and result in players getting banned. AMD is collaborating with Valve to fix the issue, but in the meantime, players are advised to disable the Anti-Lag+ feature.
