Sample high-resolution pointer event intervals to measure average Hz, peak reporting rate, and sensor stability up to 8000Hz.
| Polling Rate (Hz) | Report Interval ($\Delta t$) | Common Hardware Tier | CPU Interrupt Load |
|---|---|---|---|
| 125 Hz | 8.00 ms | Standard Office Mice / Bluetooth | Negligible (< 0.1%) |
| 500 Hz | 2.00 ms | Entry Gaming Mice | Very Low |
| 1000 Hz | 1.00 ms | Standard Esports Standard | Low (~0.5%) |
| 4000 Hz | 0.25 ms | High-End Esports Mice | Moderate (~2-4%) |
| 8000 Hz | 0.125 ms | Ultra Esports Mice (Razer 8K, Viper V3) | Heavy (~5-8%) |

Technical answers to common hardware, refresh rate, and browser diagnostic questions.
Mouse polling rate is the number of times per second your optical mouse sensor reports its coordinates to your PC. A 1000Hz mouse updates every 1.0ms, while a 4000Hz or 8000Hz mouse updates every 0.25ms to 0.125ms.
To saturate a 1000Hz+ polling rate, you must move the mouse continuously at moderate-to-high speed. If the mouse is moving slowly, the sensor only generates packets when physical coordinate changes occur.
Yes, handling 8,000 interrupts per second requires considerable single-core CPU throughput. We recommend pairing 4K/8KHz polling with modern processors (AMD Ryzen 7000/9000 series or Intel 13th/14th Gen) and playing at high in-game framerates.
