Hello,
First off i'd like to apologize as I posted this first in another section but now realize this is where the post is supposed to be!

I'm using Sony Vegas to edit a fairly large project which has nested projects. For some reason (and this has been the case on 2 computers), whenever Vegas renders the nested part only half of my CPU resources are used. If i render the the nested part separately in its own project CPU utilization is at 100%!

Any ideas on what could be causing this and what a workaround could be?
