FOpenGLDisjointTimeStampQuery

Used to track whether a period was disjoint on the GPU, which means GPU timings are invalid.

Windows

MacOS

Linux

References

Module	OpenGLDrv
Header	/Engine/Source/Runtime/OpenGLDrv/Public/OpenGLDrv.h
Include	#include "OpenGLDrv.h"

Syntax

class FOpenGLDisjointTimeStampQuery

Remarks

Used to track whether a period was disjoint on the GPU, which means GPU timings are invalid. OpenGL lacks this concept at present, so the class is just a placeholder Timings are all assumed to be non-disjoint
