S.T.A.L.K.E.R. - Clear Sky
S.T.A.L.K.E.R.: Clear Sky, is the stand-alone prequel for S.T.A.L.K.E.R.: Shadow of Chernobyl, a first-person shooter computer game by Ukrainian developer GSC Game World. The game consists of a roughly 50/50 mix of new areas and old, remodeled areas from the previous game. The X-ray graphics engine has been updated to version 1.5 and includes DirectX 10 support (later patch 1.5.06 included DirectX 10.1). Additionally, the AI received an overhaul to accommodate the new faction wars feature.
Again, good gains under Clear Sky. We're able to get over 30 FPS in the minimum department at 1680 x 1050. It's only the second card doing this here with the other being the HD 5870. At 1920 x 1200 we're just under 2 FPS away from 30 FPS, so with a bit of detail tweaking we should be able to get that over as well.
