Visible RAF intervals are browser-observed timing, not panel Hz, input latency or hardware frame skipping. Long frames exceed 1.8 times the median and 25 ms; spikes exceed 3 times the median.

Statistics cover the latest 300 visible animation frames. Long frames exceed 1.8 times the median and 25 ms. They are not a count of hardware dropped frames.

FAQ

Does this test upload my input?

Core interaction is processed in your browser. Testvexa does not intentionally upload camera or microphone streams.

Can browser limitations affect the result?

Yes. Browsers expose different hardware APIs, so unsupported access is not the same as faulty hardware.
