If you searched for gaming peripherals recently, you probably noticed that among specifications of every mouse, there is a polling rate as an important factor of mouse performance and precision. But, what is polling rate really? Is it really that important or is this just a marketing trick made up by manufacturers?
Polling rate is is a factor that determines how often mice send info the the PC main board. It is measured in Hertz, and every value is connect to the lag time. So, if mouse has polling rate of 1000 Hz, response time is 1 ms. If polling rate is increased, cursor of a mouse will be updated more often, and this is important when lag time is critical. For gaming mice, polling rate is important because of the fact that lag time will be shortened, and mouse will react faster. You can adjust mouse polling rate in the control panel, or by using switch on the mouse itself.
Polling rate is still a theme of great debate among gamers. But, no matter what, higher polling rate can be very effective, but it is hard to notice difference between 500 Hz and 1000 Hz. If you set polling rate too high, you will just waste CPU resources without any effect. If you consider buying a mouse, don’t rely on polling rate specifications too much, look for additional info about the mouse preferences and rate model with the use of synergy of all these specifications.
Polling rate of 125 Hz is most stable, and cursor of a mouse will slide much smoother than mouse with higher polling rate. But, if you think polling rate is important, find a mouse with a switch to change polling rate during the game, it will be a lot easier for you to adjust polling rate if needed.
