Don't know if it's a bug..

I have a dual-P2-400 machine, using NT4; when I do a render POV only
uses 30% of the CPU; the max it could use is 50% (it's single threaded,
right?) but why doesn't use all the CPU he can get EVEN if priority is
set ti REALTIME?

Thanks

What settings do you have for the GUI and RENDER priority ?

I tried high, highest, I even tried to set program priority to realtime using
taskManager.. but nothing..

Hmmmm....

The only other suggestion is to check for any TSR's.

It's just that is singel threaded. One thread running on a two
processor system can use up to 50% of processing power.
Try starting another rendering thread (i.e. 2xPOVray)
and the CPU should go up to 100%

It has nopthing to do with priotity or other TSRs running.
