When you render with version 3.7, the process priority in "lower than 
normal".

This means than just about every other processes have a higher priority. 
In fact, on my computer, there are only 2 process running with a lower 
priority: Idle and those of distributed computing projects that I 
participate in, like Seti@home.

The result is that your other applications will take precedance, and 
that the duty cycle setting is no longer usefull.

Historicaly, the purpose of that setting was so that a computer 
operating in zero G had less chances of overheating. There is no thermal 
convection in the shuttle or in the International Space Station.
