I can run P5 just fine with my puny 256Mb Ram. On a P4 2GHz processor, but still, runs fine. Slower than P4 but not unbearable. The reason why I mostly use PPP is coz that's the one I'm more familiar with. And of course it IS a little bit faster. Poser 4 is on it's own physical HD while P5 is just crammed in somewhere on my "all the other stuff" HD. Doesn't seem to matter too much. I'm sure it'll run faster with more RAM, but saying that P5 can't run with anything less than 512 is nonsense.

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
