What it means
The total delay from moving your mouse to seeing it on screen. It's the lag you feel in your hands, and it's separate from how high your FPS number is.
More detail
High FPS usually lowers it, but settings matter too: V-Sync and frame generation add latency, while NVIDIA Reflex and a sane FPS cap cut it. A game can show a huge frame rate and still feel sluggish if the click-to-pixel path is stacked with delay. This is the thing competitive players actually chase.
