Duty cicle was implemented to protect a computer in the space shuttle.

POV-Ray's priority on a windows system is set to "lower than normal". 
It's the task of the OS to attribute CPU cycles. On a quad core, using 
POV-Ray should not affect any application that have the focus and that 
start with "Normal" priority increased by the fact that it have the 
focus. If it causes a problem, you should complain to Microsoft so that 
they correct the problem.

There is also the possibility that your systen is set to prioritize 
background tasks.
