I've recently moved completely to vista. I'm using Vista Ultimate 32bit, but I'm having problems with multi-processing in Nuendo 3.2.

Nuendo never uses more than one core (I've got a quad-core cpu), and when I enable multi-processing it gets really choppy, so there is really a disadvantage in turning multiprocessing on for me.

Is this a known problem with Vista? Does anyone have a clue how I can fix this?
