I do have a saved preset for draft renders to check my lights.  I don't have poser open just now but  when I do I'll compare the settings to what you've listed.  I do have to lower my bucket size to 32 though.  64 is a bit too much for most scenes on this machine.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
