FramePhase enum

Various important time points in the lifetime of a frame.

FrameTiming records a timestamp of each phase for performance analysis.

Inheritance

Values

vsyncStart → const FramePhase

The timestamp of the vsync signal given by the operating system.

See also FrameTiming.vsyncOverhead.

buildStart → const FramePhase

When the UI thread starts building a frame.

See also FrameTiming.buildDuration.

buildFinish → const FramePhase

When the UI thread finishes building a frame.

See also FrameTiming.buildDuration.

rasterStart → const FramePhase

When the raster thread starts rasterizing a frame.

See also FrameTiming.rasterDuration.

rasterFinish → const FramePhase

When the raster thread finishes rasterizing a frame.

See also FrameTiming.rasterDuration.

rasterFinishWallTime → const FramePhase

When the raster thread finished rasterizing a frame in wall-time.

This is useful for correlating time raster finish time with the system clock to integrate with other profiling tools.
