Hardware Diagnostic FAQ

  • MouseTestPro queries the standard performance.now() high-resolution browser timer API, measuring event timestamps accurate down to fractions of a millisecond.
  • Mechanical microswitches deteriorate over time causing metallic leaf contact bounce. MouseTestPro isolates switch release-to-press intervals below 80ms to flag hardware faults.
  • Zero data is ever transmitted to a server. 100% of telemetry data is calculated locally inside your browser event thread for instant feedback and privacy.
  • Yes. MouseTestPro uses non-throttled PointerEvents to sample raw USB polling rate bursts up to 8000Hz without artificial main thread event caps.
