In Windows, you have 6 prioritys settings that you can sellect:
Real time (don't use that one if you want to do anything), high, higher 
than normal, normal, lower than normal and low.
There is also the idle priority, but you can't chose it.

Any application that have the focus will have priority over other 
applications that have the same base priority.
Minimised applications have ther priority further reduced, still 
relative to applications that have the same base priority.

By default, POV-Ray runs at lower that normal priority.
