Standard_Real FrameRate () const
 Returns FPS (frames per seconds, elapsed time). This number indicates an actual frame rate averaged for several frames within UpdateInterval() duration, basing on a real elapsed time between updates. More...
Standard_Real FrameRateCpu () const
 Returns CPU FPS (frames per seconds, CPU time). This number indicates a PREDICTED frame rate, basing on CPU elapsed time between updates and NOT real elapsed time (which might include periods of CPU inactivity). Number is expected to be greater then actual frame rate returned by FrameRate(). Values significantly greater actual frame rate indicate that rendering is limited by GPU performance (CPU is stalled in-between), while values around actual frame rate indicate rendering being limited by CPU performance (GPU is stalled in-between).
