In Russia Windows XP is still a common OS so I guess that is why... And we all know why a user with a computer that can run this game would choose XP?
So let the pirates rot in the future - but as the current box says DirectX 9 there is no option but to support it in the patch, no matter how much we whine... I tried starting CloD in Dx9 once for testing and got half the FPS and the visual quality was awful. It must hurt to sit there trying to fix it when 95% of the customers use Windows 7. But still - this game is released with Dx9 on the box so no choice.
