Tests/Sensor Frequency

Mouse Polling Rate Test

Track pointer movement event frequency in real time. Move your mouse rapidly across the canvas to benchmark peak and average report Hz.

💡 Tip: Move your cursor continuously in rapid circles across the box to measure USB Hz rate.
⚠️ Note:

Browser-observed rate: At high rates above 1000Hz (4000Hz/8000Hz), reported event frequency can be limited by browser event dispatch, OS compositor caps, and event coalescing. Results measure browser-observed pointer event frequency, not a direct USB HID hardware packet log.

Understanding Mouse Report Frequency

1000 Hz Standard Gaming

1.0 ms Delay

The standard for competitive gaming. The mouse transmits its coordinate packet to the USB controller every 1.0ms, ensuring near-instantaneous cursor response.

4000 / 8000 Hz Hyperpolling

0.125 ms Delay

High-end gaming sensors (Razer HyperPolling, Corsair Slipstream). Provides smoother cursor motion on 240Hz–540Hz monitors at the cost of higher single-core CPU overhead.

Browser Coalesced Events

Sub-frame API

This tool taps directly into the W3C getCoalescedEvents() API to retrieve raw micro-movements even when browser render ticks are capped.

125 Hz Office Baseline

8.0 ms Delay

Default USB polling rate for non-gaming mice and Bluetooth connections to conserve power, resulting in perceptible micro-stuttering during quick flicks.

Mouse Polling Rate (Hz) Frequently Asked Questions

  • Move your mouse rapidly inside the testing canvas. The browser measures hardware PointerEvent timestamps to calculate your sensor's USB report rate in real-time (up to 8000Hz).
  • 8000Hz reduces input delay from 1.0ms to 0.125ms and produces smoother micro-adjustments on 240Hz+ monitors. However, it requires a high-performance CPU (Intel i7/i9 or Ryzen 7/9) to prevent frame drops.
  • Polling rate drops when the mouse is moved slowly because optical sensors dynamically lower report rates during micro-movements to save power and USB bandwidth.
