Intel(R) Extreme Graphics

Laptop versions of these chipsets may work, but may run comparatively slowly. Standalone cards that are installed in vanilla PCI slots (not PCIe or PCIx or AGP), such as some GeForce FX variants, will perform poorly. Integrated chipsets such as the ATI Xpress and the NVIDIA TurboCache variants will have low settings selected, but should run satisfactorily.

Please note that attempting to play the game using video hardware that isn’t listed above may result in reduced performance, graphical issues or cause the game to not run at all.

The NVIDIA GeForce FX series is unsupported under Vista.
