**Brian S - I have a AMD64 4000+ and no render problems with check your updates and video drivers - the Poser 4 problem is because of the amount of memory you have (to much for it) I dont know if the patch from efrontier fix's this or not but I do know that some one on the net created a wrapper that tells Poser you have less ram then you really do have sorry I can't remeber the web site but a google search with your Poser error code should direct you there.

Good luck
