S.T.A.L.K.E.R.: Clear Sky is the prequel to the immensely popular S.T.A.L.K.E.R.: Shadow of Chernobyl, and is developed by GSC Gameworld. This First Person Shooter features an updated X-Ray graphics engine that includes DirectX 10 support and improved AI. You play Scar, a S.T.A.L.K.E.R. that patrols the "Zone".



  • Game Settings: Extreme
  • Anti-Aliasing: x2
  • DX10








Higher Scores = Better Performance


The top performing multi GPU combo in this benchmark is the GTX 285 at both resolutions. The quad GPU giants just don't perform well enough to overcome the GTX 285. With that said, the quad GPU setups offer very little in the way of a differential in performance from one manufacturer to the other in both of the resolutions tested. The difference in performance from ATI to Nvidia is one to two frames per second. Both SLI and CrossFire seem to scale in this game, offering a performance increase, and making a dual GPU setup worthwhile.
