This news is a little late, but important nonetheless: The PC version of Call of Duty: Black Ops 2 won't support Windows XP, because the engine has been upgraded to DirectX 11.'But my computer is for serious things, like charts.'

The operating systems supported are Windows Vista and Windows 7.As a result, Black Ops 2 has "enhanced lighting, shadows, anti-aliasing, bloom, depth of field, ambient occlusion and other enhanced effects that are still in the works",a FAQ on the game's website revealed. "And the game can run at higher resolutions and higher frame-rates on the PC."DirectX 11 more efficiently uses the processing power of a graphics card, too, which benefits "the entire range of supported GPUs".Black Ops 2 PC performance has also "significantly improved", and there will be more quality vs. performance options to play around and get your desired result with. There's no frame-rate cap.
