Description

This extension automatically paces the CPU to make sure it does not get too far ahead of the GPU, reducing the latency between inputs received and updates on the screen. Additionally, Anti-Lag+ offers applications the ability to inform the driver when input processing begins, in order to align the timing of display updates, enabling even lower latency between receiving input and displaying on the screen.
