Frame Skipping Test

Look for irregular frame presentation gaps.

Browser-observed measurementPrivacy-first

Tests run locally in your browser. We do not upload keystrokes, pointer paths, or media.

Important

  • Browser timing mode measures rAF presentation intervals, not guaranteed panel drop counts.
  • Visual gaps may come from display, OS, browser compositor, or camera — not a hardware certificate.

Measures browser presentation timing via rAF — not a hardware “dropped frames” certificate. Long intervals are possible irregular browser frame timing.

How to use

  1. Choose Browser timing diagnostic or Photo-assisted visual pattern.
  2. For timing: Start, keep the tab focused, review long-frame metrics.
  3. For visual: Start motion, optionally photograph with long exposure.
  4. Record your observation locally — the page does not analyze photos.

What the result means

  • Results are browser-local observations with explicit limitations.
  • See Limitations for what this tool cannot claim.

Limitations

  • Browser timing mode measures rAF presentation intervals, not guaranteed panel drop counts.
  • Visual gaps may come from display, OS, browser compositor, or camera — not a hardware certificate.

Is this a hardware laboratory result?

No. DeviceMetrik reports browser-observed or visual-aid results with clear limits.
