I second the request: can we see some screen shots of render settings? How many lights do you have in the scene? What are the light settings?
Obviously, these settings may not work for everyone, but it'll give a good starting point.

And most importantly, what are your system specs? Are you rendering a beautiful scene at 100% quality, but it takes 10 hours on a 64-bit, quad-processor system with 32G of RAM?

The reason I ask for some sample render settings is that last night I tried to render a scene using indirect lighting using one light, a V2 figure, the ground plane, and set to 750x750 pixels.
After 30 minutes, the entire Poser 8 screen was "white", which is the way Windows says "This program isn't responding to requests to redraw it".
By comparison, a global-illuminated scene in Lightwave, at Enhanced-Medium setting, and 1000x1000 pixels is almost finished in 20 minutes... and I can see the render progress as it happens.

Granted, I know this is the first version of Poser to attempt real GI lighting, so I wonder if my settings are too high... or if my computer is too old to handle all the calculations that Poser is doing.
