Understanding Keyboard Polling Rate

Tap each step to follow along in order.

  1. What polling rate means

    Polling rate is how many times per second a keyboard reports its input signal to your computer, measured in Hz.

  2. Common polling rate values

    Budget keyboards mostly use 125Hz (8ms), while gaming keyboards often support 500Hz (2ms) or 1000Hz (1ms).

  3. How it relates to input lag

    A higher polling rate shortens the gap between the moment you press a key and the moment your computer registers it, which can make reactions feel noticeably snappier in games where speed matters.

  4. Check your current polling rate in software

    Installing your keyboard manufacturer's companion software lets you see the polling rate it's currently set to.

  5. Change the polling rate

    In that same software, you can usually choose between 125Hz, 500Hz, and 1000Hz β€” raising it can increase CPU usage very slightly, but the effect is normally negligible.

  6. The real-world difference

    For everyday typing or document work, the difference is barely noticeable, but in fast-reaction games like shooters or rhythm games, a higher polling rate can genuinely be felt.

An invisible number that changes how fast your input feels

Polling rate never shows up directly on screen, but it quietly determines how quickly a keypress actually reaches your computer. If you play competitive, reaction-heavy games, it's a setting worth checking at least once.

Pair it with your display's refresh rate

A fast-reporting keyboard matters most when the rest of your setup can keep up β€” a high polling rate paired with a low-refresh-rate monitor still bottlenecks how smoothly that faster input actually shows up on screen. For competitive play, it's worth treating input speed and display refresh rate as a matched pair rather than optimizing just one.

Frequently Asked Questions

Should I always max it out at 1000Hz?

In most cases, yes β€” the benefit generally outweighs the very slight increase in CPU usage, though it's fine to dial it back if you notice any impact on an older or lower-spec PC.

Does a mouse have a polling rate too?

Yes, mice work on the same principle, and gaming mice commonly ship with the same kind of software for adjusting their polling rate.
