01

Razer specifies a Focus Pro 30K optical sensor for the DeathAdder V3 Pro.

02

Razer's current support page documents polling support up to 8000 Hz when used with the compatible HyperPolling Wireless Dongle; browser event estimates are not a substitute for device-level polling measurement.

Test matrix

What to test and what a pass actually tells you

Run the test closest to the symptom. A passing result narrows the diagnosis; it does not certify the entire device.

Mouse Button TestVerify left, right, middle, and extra mouse button events.

A pass proves browser input events are arriving; app/game mappings, profiles and accessibility settings move higher on the list.

Mouse Button Event ViewerSee browser button numbers for left, middle, right and additional mouse buttons that reach the page.

A pass proves browser input events are arriving; app/game mappings, profiles and accessibility settings move higher on the list.

Double Click TestCheck intentional double-click timing and event detection.

A pass proves browser input events are arriving; app/game mappings, profiles and accessibility settings move higher on the list.

Unwanted Double-Click TestLook for unintended duplicate clicks from one physical press pattern.

A pass proves browser input events are arriving; app/game mappings, profiles and accessibility settings move higher on the list.

Mouse Polling Rate EstimateEstimate pointer event frequency in the browser.

A pass proves browser input events are arriving; app/game mappings, profiles and accessibility settings move higher on the list.

Evidence handoff

If the browser cannot reach the suspected subsystem

Keep the browser result as one observation, then move to the operating system or manufacturer diagnostic that can see the protected hardware state. Do not interpret an unsupported browser API as a failed component.
