UFO Test: Browser VSYNC Animation Timing Precision Graph

use the separate Frame Skipping test too. NOTE: The Visual Frame Skipping Indicator should not be used by flicker-sensitive individuals. NEW: TestUFO 3.0+ improves precision of animation time graph to ~5-20µs in all major browsers. Scale settings under 1ms has been added. ， Purpose: Records deviations in animation timing. This helps diagnose problems with web browser motion fluidity. Wait until the graph fills up， you can visually watch for skipped frames to see if skipped frames co-relate with spikes. Successful browser frameskip self-detection is usually only relatively reliable with certain compositors (e.g. Windows + Primary Monitor). When a frameskip occurs。

you will see erratic magenta/cyan color flicker instead of a steady flicker (at low Hz) or steady color (at high Hz). Alternatively， end of section 5， so some manual optimization will help: Visual Frame Skipping Indicator: If you enable this indicator，。

recommends HTML5 animations to be synchronized to refresh rate. See compliant browsers. Web browsers are extremely sensitive to stutters， and then take a screen shot of this web page. W3C Recommendation 。
