frametime
FrameTime is the duration between the start of one frame and the start of the next in a sequence of rendered frames. It is typically expressed in milliseconds or seconds and is a fundamental metric for real-time graphics, animation, and video playback.
FrameTime is inversely related to frame rate. If a target is 60 frames per second, the ideal
Measurement typically captures the total time to render and present a frame, including CPU work, GPU rendering,
Variability in FrameTime affects perceived smoothness. Large spikes or uneven pacing, known as jank, detract from
Applications include performance tuning, benchmarking, and monitoring in games, simulations, and media players. Analyzing FrameTime distributions
Common reference values: at 60 Hz displays, aim around 16.6–16.7 ms per frame; at 120 Hz around
