Laurie S Like Incarnadine I have a P4 but am running 2 512 meg sticks of Rambus PC800 My render times are quarter of what they were in Bryce 4 even using soft shadows anf volumetric textures. Unfortunately I happened to get a bad mobo and am currently down till I can decide on a good replacement. It is an Abit TH7 Raid. If Incarnadine has any advice in that department I would appreciate it.
