i also get this problem. Im using 9800gt

ok i think i got this figured out, old graphic or nvidia graphics dont support windows 7 directx11 , nvidia onyl supports up to dx10 which it will revert to when it can handle dx11 which i think is the problem, maybe we should downgrade to windows vista or move on to radeon?

whatever it is, its super frustrating as i only have some spare time over the weekends and i want to commit my quality time by indulging my 12 years of wait, if i dont get this done i will commit seppuku

All my problems solved by deleting and installing back again. The 1st time i installed it i noticed that i was cramming my pc with too much program, thats why the installion didnt go well. So now i can view everything perfectly, mission,movies everything is running smoothly.
