Bluetooth vs Wired Controller Connections
Neither connection is universally faster or more reliable for every controller, host, firmware, radio environment, and game. Compare one variable at a time and use the right tool for the measurement.

What the browser result means
This website reports browser-visible input and Gamepad timestamp cadence. It does not see every transport packet and cannot measure controller-to-screen latency, USB bus intervals, Bluetooth retransmissions, packet loss, or radio quality directly.
Safe decision path
- 1
Establish the same test conditions
Use the same controller, browser, foreground tab, power state, gamepad profile, and physical actions. Change only the connection path.
- 2
Repeat the wired observation
Use a known-good data cable and direct port. Record detection, mapping, disconnects, stick paths, button transitions, and cadence confidence across repeated runs.
- 3
Repeat the wireless observation
Pair normally, keep distance and interference consistent, and repeat the same actions. Note disconnects or visible stalls rather than inferring radio packet loss.
- 4
Compare the actual symptom
If the concern is in-game delay or missed inputs, reproduce it in the same game and settings. Browser cadence alone cannot explain game-engine or display latency.
- 5
Use native measurement when needed
For exact report intervals or end-to-end latency, use a documented native tool or hardware capture whose method matches the question.
Verification standard
A meaningful browser comparison should repeat across foreground runs with medium or high cadence confidence and the same mapping. Exact latency claims require a separate native or hardware method.
Before advanced work
USB filter drivers and polling overrides can affect system stability, security, and other devices. Do not install or change them solely because one browser estimate differs. Use the cadence and polling guide before considering any driver-level work.
Common questions
Does the comparison page measure latency?
No. It shows relative browser-observed input sessions under the same page environment. It intentionally does not issue latency or hardware-health verdicts.
Does wired guarantee zero packet loss or lower delay?
No universal guarantee can be made. Cable quality, ports, firmware, USB scheduling, controller implementation, radio conditions, and the game all matter.
Can browser cadence confirm an advertised controller report rate?
No. Browser-observed cadence is not a direct USB report-rate measurement.
