Browser hardware tools
Understand what this browser sees before comparing results. These focused checks explain their limits; they do not certify your hardware or measure your nervous system.
Display
Refresh rate, FPS & frame pacing
Observe browser callback cadence, interval spread and long intervals. Not a physical panel-Hz or frame-skipping detector.
Motion clarity: visual observation
Compare a moving browser pattern at a declared CSS-pixel speed. Visual observation only, not a GtG, MPRT or input-lag measurement.
Mouse
Mouse polling: browser observations
Inspect browser event dispatch and coalesced sample cadence separately. Not a certified USB polling rate or a click-latency measurement.
Mouse button, hold & wheel checker
Review buttons, repeated clicks, hold continuity and scroll deltas in one local checker. Browser observations, not switch or wheel fault diagnosis.
cm/360 sensitivity calculator
Calculate a linear-model turn distance from your DPI, sensitivity and documented yaw coefficient. Not measured DPI, physical calibration or an optimal setting.
Understand your setup
Change one setting at a time, keep the same browser and input, and repeat. Browser observations cannot isolate physical input or display latency.
