Constructor.

Parameters

InOpenGLRHI	RHI interface
InBufferSize	Number of buffered measurements

Member Function Documentation

EndTiming()

void FOpenGLBufferedGPUTiming::EndTiming

(

)

End a GPU timing measurement. The timing for this particular measurement will be resolved at a later time by the GPU.

GetTiming()

uint64 FOpenGLBufferedGPUTiming::GetTiming

(

bool

bGetCurrentResultsAndBlock = false

)

Retrieves the most recently resolved timing measurement. The unit is the same as for FPlatformTime::Cycles(). Returns 0 if there are no resolved measurements.

Returns

Value of the most recently resolved timing, or 0 if no measurements have been resolved by the GPU yet.

InitResources()

void FOpenGLBufferedGPUTiming::InitResources

(

)

ReleaseResources()

void FOpenGLBufferedGPUTiming::ReleaseResources

(

)

Releases all OpenGL resources.

StartTiming()

void FOpenGLBufferedGPUTiming::StartTiming

(

)

Start a GPU timing measurement.
