Well i have 1,5 Gb. I also have an PC with 1,5 Gb memory, AMD 64. Thats running XP Both machines are upgraded to the latest available Poser 5 version and OS. When i open the same poser5 composition. I dont have the irritating wait times when you only move your mouse over the objects. When i check with the top command in OSX is see that poser is consuming all of the CPU power, so that's causing the wait. So maybe its a serious BUG inside the OSX version. Ok when i only load an figure and some clothes no problem, but with some real nice building.. its takes forever.. Is there no other way to troubleshoots this behavious, because its (in my opinion) totally unexectable, and you really can not work this way on an mac. Tried also to do the same thing in Daz Studio, and that progam does it with NO real CPU time taken. So i guess its an real Poser5 OSX issue...
