many of these things do not presently translate to other programs so if you render exclusively in bryce say, then no the p5 upgrades won't make your present figures better. but if you render in Poser there's no doubt they'll even make your High rez figures look better. for example displacement mapping is a much more realistic version of bump mapping where the map actualy does deform the skin causing lighting to model textures much more accurately. subdivision of surface poygons will make any curved surface smoother, in effect creating more polygons. the firefly renderer will put reflections on objects rather then using a texture map to simulate them. Node based shaders will allow a flexability of textures, layers, translucency, previously unavailable in a consumer level product (by consumer level I mean a program that costs less then the computer it's run on)
