Does 8,000Hz polling reduce mouse input delay?
A rate of 8,000Hz corresponds to a nominal report interval of 0.125ms, compared with 1ms at 1,000Hz. More frequent reports can reduce the time spent waiting for the next report. This does not establish an equal improvement in total click-to-display latency or guarantee smoother performance in every game.
Scope: this is a technical explainer using polling-rate arithmetic and manufacturer documentation. It is not a Nexrivium hardware benchmark.
Polling intervals and theoretical waiting time
The nominal interval in milliseconds is 1000 / polling rate in Hz. If an event arrives uniformly between reports, the average wait to the next report is half that interval. This simplified model excludes the sensor, firmware, wireless transport, operating system, game engine, rendering queue and display.
| Polling rate | Nominal interval | Modelled average wait |
|---|---|---|
| 1,000Hz | 1.000ms | 0.500ms |
| 2,000Hz | 0.500ms | 0.250ms |
| 4,000Hz | 0.250ms | 0.125ms |
| 8,000Hz | 0.125ms | 0.0625ms |
These are calculated values, not measured click latencies. The difference between the 1,000Hz and 8,000Hz intervals is 0.875ms; the difference between their modelled average waits is 0.4375ms. Neither number should be presented as a measured end-to-end improvement.
Why real results differ
Razer's HyperPolling documentation describes higher reporting frequencies and publishes vendor measurements with defined measurement endpoints. Those results belong to the specified devices and setup; they are not measurements performed by Nexrivium. A mouse model, receiver, firmware version and software configuration can matter as much as the selected polling rate.
Reports per second also do not equal displayed frames per second. A game may sample or process input differently from another game, and the rendering and display pipeline adds its own delays. Increasing polling cannot by itself eliminate shader stutter, rendering stalls or every source of uneven motion.
How to compare settings on your own PC
- Record the mouse model, connection, firmware, DPI, Windows build, game version and display refresh rate.
- Keep the test scene, graphics settings and frame cap consistent.
- Compare 1,000Hz, 2,000Hz, 4,000Hz and 8,000Hz where supported, repeating the same movement and scene several times.
- Record frame-time behavior and any visible stutter. If measuring latency, name the tool and the exact start and end of the measured interval.
- Keep raw results and their variation. Do not describe a subjective impression as a sub-millisecond measurement.
If a higher rate introduces instability, compare lower supported rates and consult the device maker's troubleshooting guidance. This page does not assign a universal CPU-overhead percentage or promise a competitive advantage.
Choosing a polling rate
Use the highest supported rate that works consistently in the games and configuration you actually use. A higher setting is not a substitute for a stable frame rate or a comfortable mouse. Our mouse guide covers related selection criteria; the review methodology explains what a reproducible benchmark must include.
Source and correction
Correction — September 28, 2026: this page previously included an empirical latency and CPU-load table without an accompanying reproducible protocol. That table and unconditional performance claims have been removed. The intervals above are theoretical calculations, not replacement test results.
