G4 400 using 9.2.2 , 1.5 gig Ram. Couldn't render the Dragon and Hiresmaps with 500MB allocated to poser, upped the allocation to 700MB and everything worked fine. The dragon is a beauty but extremely RAM hungry with the maps at hires, Renders pretty quickly though. Give poser all the Ram you can allocate :-) Plopped a render in the poser gallery if your interested, search for RonGC to get to it.
