S.T.A.L.K.E.R. Clear Sky is a very eerie game. The Zone is a huge abandoned territory, with twenty-year-old dilapidated buildings, overgrown with forests and anomalous vegetation. It is a territory with deserted surface and underground research facilities, neglected military bases and testing grounds for new technologies. The radioactive land is covered with sores of burned out soil, poisonous fogs, and deadly gravitational anomalies. It is a world of a terrible anthropogenic disaster, and in the center of this hell sit the remains of the Chernobyl Nuclear Power Plant.
The in-game Zone is a reconstruction of the Chernobyl Nuclear Power Plant and the 30-kilometer Exclusion Zone around it. Moving along the storyline, the player will visit such places as the Swamps, the Red Forest, the Limansk city and, of course, the sarcophagus of the Chernobyl Nuclear Power Plant. Many in-game locations have real prototypes.
The GTX580 is a perfect card for STALKER at this resolution, managing to keep the frame rates above 30 at all times. The overclocked AMP! produces a couple of extra frames per second when directly compared to the reference card.
