just bought a gateway with windows 8 and can't play some of the games I used to play. I get an error message that says something like "no 3D acceleration or you may have to reboot your system." I was able to play games in xp, vista and 7. I have AMD RADEON 7640G w/graphics system memory (what ever all this is). When I go into my display properties (I think) I did see Standard 3D. Is there anything I can do to solve these gaming issues?
