@ LSD :P Your video card does not even qualify (:P), you can use it, but i seriously doubt that any software can feed openGL card in real time (50fps, or even 25) with scenes which have milions and milions polys in it, as Bryce usually has, with couple terrains here and there (expecialy on gforce4). :D Try to import your castle you made in Rhino into Maya (and I mean full model, no polygon reduction used in Maya) and then test it !!! :P
