MouseTester v0.2.10
A fix-focused release — mostly things that keep the tool honest about itself.
What's fixed
- The "sweet spot" recommendation is now honest. Compare ranks each rate by its typical (median) delivery across your runs, so it points you to the rate that's consistently clean — not the highest rate that happened to nail it once. On a system where 8000 Hz is sometimes great but often stutters, it now correctly recommends the steadier rate (the whole point: the highest stable rate, not the highest number).
- Per-mouse USB power saving now reads the real state. The "Check power saving" panel used to show a stale "On" for your mouse even after you disabled it (a custom power plan could trigger this). It now reads the exact same Windows state it writes, verifies the change actually took effect (no more false "done"), refreshes the panel immediately, and shows "Mixed" when a composite mouse's interfaces disagree.
- Reopened runs no longer hide their worst spike. Double-clicking a saved run on the Compare page now always shows its worst gap and worst batch in the graphs — the earlier downsampling could drop the single biggest outlier, and a saved graph should never look cleaner than the real run.
- Power tweaks are truly reversible. The optional power tweak now changes nothing if it can't save a restore point first, so "Restore settings" always has something to restore.
- The tool stays out of its own measurement. Power-saving actions are blocked while a test or capture is running, so checking/changing power settings can never disturb a live reading.
A free Windows tool that measures how evenly your mouse's input is delivered to the host — honest that this is host-delivery timing, not a device polling-rate or latency claim.
Highlights
- Quick Test with a plain-language delivery score
- Advanced / Lab metrics + a live interval graph (double-click it for a labeled full-screen view)
- Compare your runs, find your stable sweet-spot rate (higher Hz isn't automatically better), and double-click any run to reopen it — values, ratings, and graphs
- Optional power-saving check / disable / restore (reversible, admin-gated)

Honest status
Internally credible, not yet validated across many mice / PCs. Feedback from different hardware is very welcome.
Reports Windows host raw-input delivery timing, not physical USB/HID polling timing.
