Impetuousxhow many times a second your keyboard or mouse reports presses, or its position in the case of a mouse to the computer. poling rate can also refer to for example, the frame rate of a monitor. like 144hz, for example.
Impetuousxit is an issue sometimes, but only if you play vsrg's like osu mania or other rythem games. for most everything you don't need to worry about polling rate tho so if you don't play any of those games, it won't matter too much, and the average person wouldn't be able to tell a difference.
