VR performance counters, opinions on if this looks right or not

[STKDirty]

Hi, just wanted to get opinions if this looks ok or not.  I don't really have any issues, but wondering if the constant oscillating of the frame and simulation lines looks right or if it should be a straight line.  The frame time seems to jump between 11 and 20 really fast.  Thanks!
