Don't know if you can do this already but it would be useful to be able to turn on and off low priority when rendering to maximise speed when you aren't usng the computer for other stuff.
this works with all processes, except they are locked (like firewalls, virus scanners, system kernel, etc..).. and never put it to "echtzeit"(realtime) although it seems tempting
Mihai that doesnt seem to happen with me - if I set it to low priority its much slower. Or maybe I just had the number of threads set low - i'll have to test it out again.
