About 3 seconds · Method 3.0
Warm up visible animation, measure requestAnimationFrame intervals for 2.5 seconds, and report observed presentation cadence, median and P95 interval, timing jitter, frame count, and missed intervals.
Test setup
Runs the Display measurement used by this test.
Close heavy tabs and keep the same power mode when comparing devices.
Ready to run
Transparent method
The workload, raw readings, progress, and final browser score are visible. Scores are a relative 0–100 reference under similar conditions, not a hardware certification.
Useful context
No. This tool estimates presentation cadence from visible animation timing and labels it as an observation rather than a hardware query.
Variable refresh rate, power saving, background work, browser scheduling, and moving the window between screens can affect timing.
