Yes, because NT needs more memory than Windows 95/98/ME.  Then there is less
left for POV-Ray and you get the performance problems.  It is important to
keep in mind that certain portion of memory cannot be swapped to disk, so
even if your scene takes much less than 128 MB you run into problems.
Upgrade the NT system with more memory and the problem will at least be
reduced.  Of course there can be millions of other configuration reasons why
POV-Ray is slower on your NT system.

There surely isn't an internal switch in POV that makes it run slower when
the system is NT ;-)
