Hi,  I have POV version 3.1g.watcom.win32 running under Win2000 on an AMD
athlon CPU.  With POV as the only busy app, rendering an animation, I have
noticed that the 'pvengine.exe' processor utilization while rendering
lingers around 80%-90%, especially when the frames render quickly -- more
time seems to be spent shuffling windows than rendering, and between frames
utilization can drop below 60%.  Oddly, this effect can be overcome by
opening a file menu and leaving it open, or by clicking and holding a
scrollbar slider - this can cause my 320x240 animation to render up to 30%
faster.  Setting render priority does not resolve the problem.

Is this a known problem, and if so is it considered an important issue?
It's certainly important to me since I want to be using the whole processor
when the only thing my computer is doing is rendering frames.

I've also noticed this problem with older versions of povray.

Thanks,
Jesse
