Controller stick drift test
Sample resting stick positions and compare their offset with a chosen dead zone.
Diagnostic visuals retain their original colors and remain visible. Presentation filters and high contrast apply outside this workspace; device-level filters may still affect your observation.
Release both sticks, choose a dead zone and sample their resting positions for five seconds.

How to run this check
Release both sticks, choose a dead zone and sample their resting positions for five seconds.
Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
Drivers may apply dead zones before the browser receives axes. A threshold is your comparison setting, not a certification limit.
If something seems wrong
Repeat after rotating and releasing each stick. Compare USB, another game and manufacturer calibration.

Is anything uploaded?
Raw diagnostic input and media are processed locally. Standalone results remain in page memory. Guided checks offer optional coarse session recovery for 24 hours; it excludes media and detailed measurements. Hosting and Google Analytics requests still leave your browser. Analytics receives only broad test-usage categories, never these diagnostic contents. See the privacy policy.
Does a pass guarantee my hardware is healthy?
No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
