It's fine that it's an operating system limit. My point was there are other apps that render BETTER than poser, at comparable prices, that don't worry about memory at all. I mean, I casn start a complex render in Vue and then do other stuff on the same computer without my machine being dragged to a crawl. Not so with Poser. And I've still seen P5 exceed the 2 gig limit (combined VM and Actual RAM), maybe it was just a refresh issue with task manager, but I've seen it.
