Did you save the poserimport to an vob (vue object)? If I import Poserfigures to Vue, I open a new scene, import the figure and saved it under an vue object (mouse rightclick save object). In my existing scene I load this vob's and there are no problems with my NVidia FX card. Try to change the preferences from Open GL 2.1 (shader 4) to Open GL (fixed hardware pipeline).
