I am on a, imac G3, 500/768meg, OS9.22 running P4w/ProPack. I can put Mike &Vicky w/med. textures together, dress them in Adventurers clothes, add Posable hair, wonderwedge and some props, lights & shadows. Hi rez textures bog me down with stephanie, but if I reduce lights and shadows I'm okay. Still slow, but ok. Ok I have given most of my memory to poser, but I can still run photoshop in the background and switch between them by hiding the one I'm not using at the moment.
