Performance was tested using the SKELETONS VS 3D AUDIO VR app and Unity 4 Profiler.

The Unity profiler shows real-time performance parameters, but doesn't provide average, median, minimum or maximum values during the entire profiling session. The CPU load in the chart, therefore, are obtained via the "eyeballing" method, and are not 100% precise.
