Detailed Description

Encapsulates GPU profiling logic and data. There's only one global instance of this struct so it should only contain global data, nothing specific to a frame.

Constructor & Destructor Documentation

◆ FOpenGLGPUProfiler()

FOpenGLGPUProfiler::FOpenGLGPUProfiler ( )

inline

Member Function Documentation

◆ BeginFrame()

void FOpenGLGPUProfiler::BeginFrame ( )

◆ Cleanup()

void FOpenGLGPUProfiler::Cleanup ( )

◆ CreateEventNode()

virtual FGPUProfilerEventNode * FOpenGLGPUProfiler::CreateEventNode	(	const TCHAR *	InName,

◆ EndFrame()

void FOpenGLGPUProfiler::EndFrame ( )

How long, in seconds a frame much be to be considered a hitch

How many old frames to buffer for hitch reports
