Yeah, it depends a lot on versions and certainly OS. I'm on Word2002. Earlier versions (of anything, really) tend to be less memory efficient. When I run a render on the Win98 machine, the rest of the stuff slows down quite a bit and individual progs tend to hog all the CPU. On XP, I can run a render, a download in the background, plus loads of other heavy apps with no slowdown and everyone sharing memory happy happy! The only exception I've found is Poser. It instantly grabs ludicrous amounts of memory and hogs it in a nasty fashion. A simple scene with Michael2 & Vicky2 grabbed a whole gig and whilst it rendered nothing else would function. Also - has anyone else noticed that Poser uses between 10 and 20% CPU even when idle? Why? Maybe I should post this in the Poser section. And maybe I should shut the hell up. Sometimes I am so f***ing boring...
