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.
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.
Minimum system requirements are:
- CPU: Intel Core2 Duo E8200 2.66 GHz or AMD Phenom X3 8750 2.4 GHz
- RAM: 2GB for 32-bit OS or 4GB for 64-bit OS
- GPU: Nvidia GeForce 8800GT 512 MB or ATI Radeon HD 3870 512 MB
