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.
HD 4850: A boost can be seen in the minimum department at 1680 x 1050, but apart from that there's not a whole lot of movement.
HD 4870: While the 2560 x 1600 minimum is down (even after trying a reboot and a few other things), averages are slightly up with a big minimum boost at 1920 x 1200.
HD 4870 X2: 1920 x 1200 manages to see some gains, while not a whole lot is seen at our other two resolutions.
