Operaguy,

     As to the Seperate Process Renderer, it isn't quite ready for prime time.

Moderate High Quality Render
Render time = 842.21 seconds. 2 Cores/2 Threads
Render time = 919.93 seconds. Seperate Process Render 2/2

Not only did it take longer, but there was noticable color banding in the background of the image that was not there when rendered at the same settings rendering directly in Poser. Also, it still ties up Poser while using the seperate process render, so there is no advantage there. Seems like a feature they didn't really finish development on and just stuck it in there. I'm guessing we'll see an improved version or offshoot in Poser 8?
