PCGH was able to get their hands on the retail version of the FPS titled S.T.A.L.K.E.R.: Clear Sky and have also revealed the system requirements for the game.

There are four different types of requirements: Minimal, recommended, optimal, and extreme. All I know is that you better have a pretty good computer in order to run the game using the extreme requirements.

Check out the screenies, the one on the right is showing the minimal graphics, while the others are showing recommended, optimal, and extreme (recommended and optimal are left to right, extreme is on the bottom).
