Polling rate determines how often your mouse reports its position to the computer.
Polling rate is the frequency at which your mouse reports its position to your computer. A 1000Hz polling rate means the mouse is sending data once every millisecond. For modern competitive gaming, 1000Hz is the standard, though newer "Hyper-Polling" mice can reach 4000Hz or even 8000Hz.
Higher polling rates result in smoother cursor movement and reduced input lag. At 125Hz, there is an 8ms delay between your movement and the computer seeing it. At 1000Hz, this is reduced to 1ms. On high refresh rate monitors (240Hz+), the difference in smoothness is clearly visible during fast flicks.
It's not just the peak number that matters; it's the stability. A mouse that fluctuates wildly between 500Hz and 1000Hz will feel "jittery" in-game. Use our real-time graph to ensure your sensor is maintaining a consistent reporting frequency while you move.
