0.87g has essentially resolved the CPU load issue. It's now close enough that the remaining difference can be chalked up to new features added.
madVR 0.86.11 = 1.52% +/- 0.02% CPU load
madVR 0.87g = 1.63% +/- 0.02% CPU Load
The special 'cyber' build seems slightly worse with 1.67% +/- 0.02% CPU load.
