- Why do other browser tests show 60 or 144 Hz?
- Because browsers deliver at most one pointer event per animation frame, so a naive counter measures your screen rather than your mouse. This test asks for the samples that were folded into each frame, which is where the real report rate is hiding.
- Why is my 1000 Hz mouse showing around 900?
- Some loss is normal: the browser is not a driver, timing jitters, and USB frames occasionally arrive late. A steady reading in the high hundreds means the mouse is running at 1000 Hz.
- Does a higher polling rate make me better at games?
- It lowers the delay between moving the mouse and the cursor reacting, by fractions of a millisecond above 1000 Hz. The step from 125 to 1000 is noticeable; the step from 1000 to 8000 is measurable rather than felt, and it costs processor time.
- Does this work on a laptop trackpad?
- It reports something, but the number means less. Trackpads report at their own pace and often smooth the input first, so treat the figure as a curiosity rather than a specification.
