Performance

CPU Markers

There are several CPU trace events in the HDR plugin to help assess CPU performance costs. They are as follows:

Marker Name	Work	Thread
FSweejHDRSourceDataOverride_GetSourceDataOverrides	Applying the results of HDR calculations to distance attenuation	Audio Thread
FSweejHDRSourceEffect_ProcessAudio	Metering of sounds' peak amplitudes in a source effect (expect many short calls)	Audio Render Thread
USweejHDRSystem_Update	Amalgamating metered values and performing HDR system calculations for the whole system, then for each HDR sound individually	Audio Thread
USweejHDRSystem_OnNotifyAddActiveSound	Detecting whether new sounds are HDR enabled and creating a source effect instance for those sounds	Audio Thread
