Zero-installation latency and sensor diagnostics for mechanical keyboards, optical gaming mice, click speed, and human reflex reaction times.
Benchmark single-click, butterfly, and jitter click speeds with 1s, 5s, 10s timers and live waveform.
Measure your visual reaction time in milliseconds with 5-trial median scores and percentile ranking.
Benchmark internal keyboard MCU scan rates and USB report intervals from 125Hz up to 8000Hz.
Verify scroll direction, step speed, and detect faulty encoder jitter or accidental jump/reversal glitches.
Sample real-time pointer report intervals. Plot live Hz curves and calculate standard deviation jitter.
Test hand-eye coordination, target acquisition speed, and click accuracy across 30 dynamic targets.
Benchmark spacebar tapping speed, stabilizer recovery, and actuation cadence with live CPS graphs.
Measure keydown debounce intervals, scan rates, and sub-millisecond response latency with tier grading.
Full 104-key visual keyboard matrix to test simultaneous multi-key rollover (NKRO) and ghosting blocks.
Calibrate true optical sensor DPI/CPI against physical mousepad travel distance.
Test gaming click speed, typing cadence, and motor reaction reflex speed.
Total system click-to-photon latency consists of three distinct stages:
Technical answers to common hardware, refresh rate, and browser diagnostic questions.
Mouse polling rate is the frequency (in Hertz) at which the mouse sensor reports position coordinates to the operating system. At 125Hz, reports occur every 8.0ms. At 1000Hz, reports occur every 1.0ms, and at 8000Hz every 0.125ms, reducing cursor micro-stutter on high-refresh monitors.
Keyboard ghosting occurs on cheaper membrane keyboards when certain simultaneous multi-key presses fail to register or register an unpressed key. N-Key Rollover (NKRO) allows every single key on the keyboard to be pressed simultaneously with 100% individual matrix detection.
Standard clicking speeds average 6.0 to 8.0 CPS. Competitive Minecraft PvP and FPS players using Jitter or Butterfly clicking can achieve 12.0 to 20.0+ CPS.
