  CPU usage in Win NT

This is probably a silly question but here goes anyway...

I have a dual cpu machine running winNT. When I run POVRay it seems to use
very little CPU time (as shown in TaskManager) usually about 2 to 5 percent.
Now, is this a misrepresentation from NT (Egads! Are you implying NT has
bugs?) or is POV not using all that it could?

Disclaimers...

1. I know POV doesn't support multi-CPUs, I'm not concerned about that right
now.

2. For those who don't know, in NT with 2 CPUs if a program is sitting in 1
CPU running full blast it will show 50% usage in TaskManager (which makes
sense to me).

3. Yep, I set POV to highest priority and nothing else is running that eats
many cycles.


This brings me to another question. What is the coorelation between the
priority setting in POV and the priority setting via the TaskManager?
Presumable when the render thread is created it takes over the priority as
set in POV and the TM priority applies to the GUI only. Yes?


Thanks,

--Rainer
