Browser event sampling notice

At ultra-high polling rates (4000Hz / 8000Hz), reported frequencies can be constrained by browser JS thread dispatching, OS compositor limits, and event coalescing. This tool measures browser-observed pointer event frequency using the W3C getCoalescedEvents() API.

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.

FAQ Reference

Mouse Polling Rate (Hz) Frequently Asked Questions

How do I check my mouse polling rate (Hz) in the browser?
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).
Is an 8000Hz (8kHz) polling rate better than 1000Hz?
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.
Why is my polling rate fluctuating during the test?
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.
Is 500Hz or 1000Hz polling rate better for competitive games?
1000Hz is standard for competitive esports, cutting USB frame latency to 1.0ms compared to 2.0ms at 500Hz. Modern computers handle 1000Hz with virtually zero CPU performance penalty.
Does an 8000Hz polling rate cause in-game FPS drops or stutter?
On older quad-core CPUs or unoptimized game engines, 8000 reports per second can oversaturate CPU interrupts and trigger stutter. Modern multi-threaded systems running modern titles handle 8000Hz smoothly.
Can I test keyboard or controller polling rate with this tool?
No. This tool benchmarks high-frequency pointer motion using the W3C PointerEvent API (getCoalescedEvents), which measures mouse sensor and pointer reports. Keyboards and gamepads do not emit pointer move events in the browser.
