I have a question about video cards. Computer has an onboard video adapter Intel 82915G/GV/910GL express chipset with 128 mb of video ram. My nephew is trying to install Ages of Empires III which calls for 64mb of video ram with support for hardware transformation and lighting. What is "support for hardware transformation and lighting"? I was going to get a new video card but i am limited. This is an older computer, Compaq dc5100 MT, 3.0 GHz, 1gb of ram with a 300w power supply and one PCI 1 express slot open, running XP Pro. Power supply does not have any extra connectors. Mostly I am trying to figure out what "support for hardware transformation and lighting" is.
