don't forget that while a DC maybe able to handle very complex 3d geometry,
this is almost certainly handled by the gfx chipset to a certain degree, the
main cpu doesn't have to be (and probably isn't) up to much in terms of
actual computing power.
now if pov could figure out a way to use the geometry engines on 3d hardware
to do some floating point crunching :P
