The processing is still done on the PC.  It's just that the result is output to the DAC on board Mercury rather than through your PC's audio system by default.  I'm not the Windows guy, so I can't help you out with this in particular.  Looking quickly through the PowerSDR settings on my test Windows box, I don't think there's an option for system audio.  You might be able to rig something up with VAC so you could listen to it.

I believe that it's done this way because there have been historical problems with differing clock rates on the computer and the OpenHPSDR rig, which cause dropouts periodically when either the buffer fills or empties.

I have some code in the Heterodyne on the Mac to push things out to the system audio, but it's not quite ready for prime time.

Precisely the same way.
