The Mouse Polling Rate Test measures how many position updates your mouse sends to the PC per second. A higher polling rate means smoother cursor tracking and lower input latency — critical for precision aiming in competitive FPS games.
What Is Mouse Polling Rate?
Mouse polling rate is the frequency at which your mouse transmits position data to the computer, measured in Hz. At 1000Hz, your mouse sends its X/Y coordinates 1000 times per second — every 1 millisecond. At 125Hz, it reports every 8ms. Between reports, the OS interpolates cursor position, which can introduce micro-jitter in fast movements.
Mouse Polling Rate Comparison: 125Hz vs 1000Hz vs 4000Hz vs 8000Hz
125 Hz — Basic
8ms update interval. Office and budget mice. Visible cursor stuttering at high sensitivity settings. Not recommended for gaming.
500 Hz — Mid Gaming
2ms interval. Mid-range gaming mice. Acceptable for casual gaming. Less jitter than 125Hz.
1000 Hz — Standard ✓
1ms interval. Industry standard for gaming mice. Used by the vast majority of competitive players. Excellent balance of latency and CPU load.
4000–8000 Hz — Ultra
0.25–0.125ms interval. Razer Viper 8K, Logitech G Pro X Superlight 2, Asus ROG Harpe Ace. Measurably smoother tracking in lab tests.
How to Change Mouse Polling Rate
- Razer mice: Razer Synapse → Performance → Polling Rate
- Logitech mice: Logitech G Hub → Device → Report Rate
- SteelSeries mice: SteelSeries Engine → Your Mouse → Polling Rate
- Zowie mice: Physical button on the bottom of the mouse
- Asus ROG mice: Armoury Crate → Mouse → Polling Rate
For Best Test Results: Move your mouse rapidly and continuously in the test zone. Slow movement causes mice to reduce their reporting rate automatically. Fast, wide circular motions produce the most accurate polling rate measurement.
Frequently Asked Questions — Mouse Polling Rate Test
The test listens for the browser's "mousemove" event and records each event's timestamp using performance.now(), which has sub-millisecond resolution. By calculating the time difference between consecutive mousemove events, it computes the interval in milliseconds, then converts to Hz (1000 ÷ interval). Moving your mouse quickly ensures the mouse sends position updates at its full polling rate, not reduced rates from slow movement.
Common causes: (1) Moving too slowly — mice reduce report rate when nearly stationary; move fast and continuously. (2) Browser event coalescing — browsers may merge rapid events for performance, artificially lowering measured Hz. (3) USB polling — your USB controller may poll slower than the mouse's capability. (4) Wireless mode — some wireless mice run at 500Hz in default mode and require software to enable 1000Hz+. Check your mouse software settings.
Modern premium wireless mice match or exceed wired polling rates. Logitech HERO sensor mice (G Pro X Superlight 2) and Razer HyperSpeed wireless mice operate at 1000Hz wirelessly. However, budget wireless mice often default to 125Hz or 500Hz to conserve battery. High-polling wireless mice (8000Hz) like the Asus ROG Harpe Ace operate at 4000Hz wirelessly to balance latency and battery life.
In controlled lab tests, 4000Hz polling provides measurably smoother cursor interpolation and slightly lower average latency. However, in real gameplay the difference is imperceptible to most players. The primary benefit of 4000Hz+ polling is reduced micro-jitter (small random deviations between reported positions), which can theoretically improve the consistency of aim tracking in fast-paced FPS games at high sensitivity settings.
At 1000Hz, mouse polling generates 1000 USB interrupts per second — negligible on any modern CPU. At 8000Hz, this jumps to 8000 interrupts per second which can increase CPU usage by 0.5–2% on older systems. For most modern gaming PCs this is imperceptible. If you notice dropped frames at 8000Hz polling, switch to 4000Hz or 1000Hz via your mouse software (e.g., Razer Synapse, ASUS ROG Armoury Crate).
The majority of professional CS2, Valorant, and Overwatch players use 1000Hz polling — the standard for nearly all competitive gaming mice. A growing minority use 4000Hz+ mice (Logitech G Pro X Superlight 2, Asus ROG Harpe Ace, Razer Viper V3 HyperSpeed). Very few professionals specifically seek 8000Hz due to the minimal gameplay advantage over 1000Hz. DPI and sensitivity settings are far more individually varied among pros.
