Polling rate decides how often your mouse tells the computer where it is. It is one of the biggest factors in how responsive your cursor feels — and one of the easiest specs to misread. Here's what the numbers actually mean.
Polling rate is how many times per second your mouse reports its position to your PC, measured in hertz (Hz). A mouse at 1000Hz sends an update 1000 times a second — once every millisecond. At 125Hz it reports just 125 times a second, or once every 8 milliseconds.
The higher the polling rate, the more frequently the cursor's on-screen position is refreshed, which makes fast movements feel smoother and more immediate. It is a completely separate setting from DPI: polling rate is about how often the mouse reports, while DPI is about how far the cursor moves per inch.
Quick definition: polling rate = updates per second. 1000Hz = one report every 1ms. Higher Hz means lower delay between your hand moving and the cursor catching up.
Each step up roughly halves the delay between physical movement and the position update reaching your system:
The catch is that the benefit shrinks fast as the numbers climb. Moving from 125Hz to 1000Hz cuts the reporting interval from 8ms to 1ms — a 7ms improvement you can genuinely feel. But going from 1000Hz to 8000Hz only trims that 1ms down to about 0.125ms. That final fraction of a millisecond is below what most people can perceive.
Higher polling rates also cost CPU time, because the system has to process thousands more reports every second. On older or busier machines, an 8000Hz mouse can actually cause stutters or frame drops that wipe out any theoretical gain. For this reason 1000Hz remains the competitive sweet spot: it is responsive, universally supported, and light on resources.

Most gaming mice let you pick a polling rate in their companion software — Logitech G HUB, Razer Synapse, SteelSeries GG, Corsair iCUE and similar apps all expose it, usually under a "Performance" or "Polling" section. Choose your rate, apply, and the setting is stored on the mouse.
Run the test a couple of times and watch the peak and average. Wireless mice on battery saving modes sometimes drop their rate, so it is worth confirming rather than trusting the box.
