Do We Need a Faster Mouse? Empirical Evaluation of Asynchronicity-Induced Jitter
summary
Empirical test uses an 8000‑Hz mouse, high‑refresh displays, a spinning‑poller logger validated against low‑level API and a theoretical jitter model, and 23 participants (9 ranked gamers). Results show a temporal jitter of 0.306 ms perception threshold for sensitive subjects, task performance shows no throughput loss up to 1 ms, and peripheral combos with recommend >2000 Hz polling perform best; polling ≤500 Hz is clearly bad and 1000 Hz can produce more visible jitter on some high‑framerate displays.
