Also I have noticed that when I use an FPS limiter and the GPU usage is near 100%, the mouse becomes less responsive. Anti-Lag is a solution to the responsiveness decline when the GPU is under full load.
Anyway as said earlier, the sinking city has terrible frame pacing and stuttering, most of which goes away with Anti-Lag enabled!
