When you view the mouse specs, essential factors come into consideration, which is the polling rate. What is the polling rate, you ask? It refers to how often the mouse reports its position and other data to your computer, measured in Hertz (Hz). Hertz measures the number of times something occurs in one second. For example, if you have a mouse with a 500 Hz polling rate, this would mean your mouse reports to your computer 500 times. Higher polling rates mean your mouse will often report with less delay, measured in milliseconds.
