It does if you frequently want part of a program to run at low priority, 
because it saves you quite some mouse clicks or keystrokes each time you 
fire up those tasks.

Another issue in this context is that POV-Ray for windows doesn't start 
a separate process (aka task) for the back-end, just separate threads, 
which might be difficult to identify in a task manager even if it 
supported per-thread renicing. Though I don't know whether Windows 
supports assigning scheduler priorities on a per-thread basis at all.
