Your GPU exceeds these requirements. You may just need to update your drivers. What operating system are you using? You can go to ati.com and download the most current version (10.7) for your OS. That is likely to solve your problem. Good luck!!!
BTW, is this a desktop or notebook system?
The os is windows 7 and its a desktop. its just that it doesnt do this with every game. whats the best gaming card out there?
