HardOCP used the new S.T.A.L.K.E.R.: Clear Sky to test the gameplay performance and image quality of ATI's and NVIDIA's latest high-end graphics cards:
Strictly speaking, S.T.A.L.K.E.R.: Clear Sky is a First Person Shooter, or FPS. But it is really much more than that. It incorporates common RPG elements such as inventory management, a large open world, defense statistics, and questing. But perhaps the most important gameplay feature is the faction wars system. There are several factions scattered throughout the Zone, such as the Clear Sky research group, the Bandits, Renegades, and the Military. Another important added feature in Clear Sky is the weapon upgrade system. With this system, you can not only upgrade your trusty weapons, you can also repair them when they become damaged.
