Which controller test should I use for stick drift or range?
Start with the stick drift test when a character or camera moves without input. Use the circularity test for uneven outer range and the calibration workflow to compare center, axes, diagonals, and complete rotations before and after a setting change.
Compare controller polling rate, latency, and vibration
The polling test estimates report frequency and interval, while the latency page helps compare repeated browser-visible input timing. Neither is a complete end-to-end hardware measurement. Use the vibration test separately to check the standard rumble actuator exposed by the browser.
