How it works

Frame interval from a chosen frame rate

Convert a positive frame-rate target to milliseconds per frame. Compare that interval with measured frame times on your target hardware. A reciprocal conversion, not a hardware performance prediction. CPU and GPU work can overlap; their timings should not simply be added. The reciprocal of average FPS does not reveal every frame duration or latency percentile. No fixed 90% performance allowance is applied.

Frame interval in milliseconds = 1000 ÷ frames per second

FAQ

No. Enter a target or a defined rate from your profiler.

No. Inspect the engine pipeline and synchronization to understand which work limits the frame.

Examine individual slow frames and a frame-time distribution in your profiler; a single reciprocal cannot describe stutter.
