My computer seems to meet all of those including DirectX compatibility.
If you could research ATI Radeon igp 320 M that would be great because then you would be able to help me a little more. I don' know what to do , whether to buy new video card or just leave it.
P.S. I did driver updates from www.ati.com in the support. It didn't seem to affect it. (CATALYST 5.1 drivers) My card is igp family for windows xp . Thanks for your time. I would appreciate some feed back.
