Povray isn't threaded so it can only use one processor at a time.  As of
yet, I haven't heard of any povray patches which will take advantage of
multiple processors on Windows/Dos systems.  You have a couple of options
though.  If you have the space and the interest, you could install Linux or
another flavor of unix and use one of the modified versions for unix.  The
other, easier option, is to render your images or animations in two parts.
Start up two instances of povray, and each instance should run on each
processor.  Have each render one half of the image and then stick it
together with paintshop pro or something.
