One thing I'm seeing (I can finally say it) is amazingly faster render times on my new dual core system. If I run P6 with the same scene as P7, I'm seeing fully about 1/2 the render times!

Now I'm finding I just always render with everything on, because, well, I can.

Before I hardly ever rendered with ray trace on at all.

Way too many people take way too many things way too seriously.
