How to Verify a Razer Mouse After Changing Hz
Test before and after changing Synapse
Run one baseline test before changing anything. Write down the average rate, peak rate, low 5 percent, and stability. Then change the polling rate in Synapse 4 and run the same movement pattern again. This makes the result easier to trust because you are comparing your own setup against itself.
Use movement that can saturate higher polling rates
High polling rates need enough movement to produce enough updates. For 4000Hz or 8000Hz, slow cursor movement often under-reports because there are not enough pointer changes to sample. Use fast circles or figure-eights for 6 to 10 seconds, then judge the average and low 5 percent rather than a single peak.
Read the result like a stability check
A clean result is not just a high peak. A useful Razer polling rate result should have an average near your target, a low 5 percent that does not collapse, and stable timing. If 8000Hz peaks but has poor stability, 1000Hz or 2000Hz may feel better in actual games.
Why browser results can differ from desktop tools
This page measures browser input event timing, not raw USB telemetry. That makes it useful for quick comparisons and real-world stability checks, but desktop tools or Razer's own utilities may report different numbers at 2000Hz and above because they can read lower-level timing data.
