It's too early to talk about system requirements, but Yerli said that you'll probably want a pretty powerful PC to enjoy the game. While they haven't identified a target CPU, you will need a graphics card with support for shader model 2.0. With that said, he noted that Far Cry was pretty scalable on a wide variety of systems once it shipped, so we can expect the same with Crysis. The game will ship with support for both DirectX 9 and DirectX 10, the upcoming version of DirectX that will be included with Windows Vista. And while the game will certainly run well with DirectX 9, he noted that you'll probably see better performance with DirectX 10 and Windows Vista, thanks to the performance improvements Microsoft has made.
