Linus observes that AMD's anti-lag+ feature works by throttling the CPU to reduce the frame buffer, which improves latency but can be misidentified by anti-cheat systems.

“basically the way that anti-le works is it periodically checks if the CPU is ahead of the GPU and if it is it throttles the CPU to send fewer frames to the GPU for processing to reduce the load on it this reduces the frame buffer thus improving the latency”
