FPS / Frame Performance Test

Measure how many animation frames this browser completes under light or controlled load. Distinct from refresh-rate estimation.

Browser-observed measurementPrivacy-first

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

Important

  • Not equivalent to a local game benchmark. Long frames are browser presentation stalls, not proven GPU drops.

Frames are recorded only after the canvas workload finishes a draw. Average FPS and 1% low use the formal post-warmup measurement window; the chart shows a short ring only. 1% low = 1000 / sorted raw P99 over the full window — not a hardware certification. Reference 30/60/120 modes pace draws; they do not prove display support.

How to use

  1. Open this tool and follow the on-screen Start control.
  2. Keep the tab focused during measurement for accurate samples.
  3. Review results, limitations, and related tools below.
  4. Use Reset to clear local trial state when available.

What the result means

  • Numbers come from browser APIs and local timing only.
  • See Limitations for what this test cannot claim.

Limitations

  • Not equivalent to a local game benchmark. Long frames are browser presentation stalls, not proven GPU drops.

Troubleshooting
