if ya hafta turn off shadows, turn off ray-tracing, turn off most of the rendering features just to churn out an image, then my suggestion is not to bother rendering it in poser. those are exactly the reasons why 3D snobs hate poser renders (that and not bothering to add facial expressions, set up proper lighting, fix deformed joints and fix bad bends because it would take too much time and effort). if poser is too slow and hard to use for renders, then use something else (maya, lightwave, carrara etc. ad infinitum) that was programmed for better renders, long before poser had any advanced rendering capabilities.
