A mouse polling rate refers to the frequency at which a computer queries a mouse for input. It is measured in hertz (Hz), with a higher polling rate indicating more frequent queries. Changing the polling rate can affect the responsiveness and accuracy of a mouse, particularly for gaming or other precision tasks.
A higher polling rate generally leads to better responsiveness, as the computer receives updates from the mouse more frequently. This can be beneficial for gamers or other users who require precise and rapid cursor movements. However, a higher polling rate can also increase CPU usage and may not be necessary for general use.
