Public Member Functions inherited from Graphic3d_FrameStatsData
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.
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).
Standard_Real	ImmediateFrameRate () const
	Returns FPS for immediate redraws.
Standard_Real	ImmediateFrameRateCpu () const
	Returns CPU FPS for immediate redraws.
Standard_Size	CounterValue (Graphic3d_FrameStatsCounter theIndex) const
	Get counter value.
Standard_Size	operator[] (Graphic3d_FrameStatsCounter theIndex) const
	Get counter value.
Standard_Real	TimerValue (Graphic3d_FrameStatsTimer theIndex) const
	Get timer value.
Standard_Real	operator[] (Graphic3d_FrameStatsTimer theIndex) const
	Get timer value.
	Graphic3d_FrameStatsData ()
	Empty constructor.
	Graphic3d_FrameStatsData (const Graphic3d_FrameStatsData &theOther)
	Copy constructor.
	Graphic3d_FrameStatsData (Graphic3d_FrameStatsData &&theOther) noexcept
	Move constructor.

	Fill with maximum values.
