I have been grooving on Render_Pattern=3 lately.  This causes the middle 
of the pic to be rendered first, which is usually where the heavy blocks 
will live. It's also good for preview.

I was doing +wt6 for awhile. I agree leaving only 2 threads is 
sufficient to have a responsive computer.  But I preferred to run +wt8 
and then turn off 2 POV-Ray threads with Task Manager while using the 
computer, and then turning them back on when done.

But, now I run Ubuntu and I have no control over affinity and priority 
anyway. ;)
