Hello,This program calls for an Open GL version 2.0 or later 3D Graphics Card,with 128MB . I want to buy a Gig Radeon HD4650 1GB AGP GV-R465D2-1Gl on an Asus P4 P800 M/Bd and Intel Pent 4 -2.88GHz CPU .I have been told that I could have trouble with the M/B supporting this AGP 8x card.Can anyone help,as there are not many AGP cards to choose from with these specs.It requires Direct X 9 or higher,and wont run on any program later than Windows XP ,which I have installed.
