Mouse polling rate refers to how often your computer and mouse communicate with each other. It's measured in Hertz (Hz), indicating how many times per second the mouse sends its position to the computer. A higher polling rate means more frequent updates, leading to smoother and more responsive cursor movement. For gamers and fast-paced tasks, a higher polling rate is advantageous, reducing input lag and improving precision. Most gaming mice offer adjustable polling rates, typically ranging from 125Hz to 1000Hz. Selecting the appropriate polling rate can enhance your overall gaming or computing experience, ensuring accurate and fluid mouse control.
