Poser would be faster if there were a way to allocate memory less stupidly, but as it is now, the system will read/write to the disk continually when using Poser, in an attempt to reserve RAM for other processes, none of which happen to need several GB of RAM. Does Safari (in the background) need a GB of RAM? No. Does Word or BBEdit (in the background) need a GB of RAM? No. But the system still doesn't know that, after all these years. It will stupidly try to reserve most of the RAM for processes other than the one you want (Poser). ISTR that Stewer or somebody said that memory management was better in G5s now, but I hate to suggest buying a G5 just to get Poser to run at the same speed it does in Windows XP.
