The events of S.T.A.L.K.E.R.: Call of Pripyat unfold shortly after the end of S.T.A.L.K.E.R.: Shadow of Chernobyl following the ending in which Strelok destroys the C-Consciousness. Having discovered the open path to the Zone’s center, the government decides to stage a large-scale operation to take control of the Chernobyl nuclear plant.
According to the operation’s plan, the first military group is to conduct an air scouting of the territory to map the anomalous fields. Thereafter, making use of the maps, the main military forces are to be dispatched.
Despite thorough preparations, the operation fails. Most of the advanced helicopters crash. In order to collect information on the reasons for the operation’s failure, Ukraine’s Security Service send their agent (protagonist – Alexander Degtyarev) into the Zone. From now on everything depends on the player.
The player must traverse through the Zone and investigate the crash sites. As the player progresses he starts learning how the helicopters were shot down. The climax of the story begins when the player reaches Pripyat to find survivors of the helicopter crashes. The player eventually meets Strelok from the original S.T.A.L.K.E.R. game (Shadow of Chernobyl) and learns of the secrets behind the Zone.
This game uses the XRAY 1.6 Engine which allows for advanced graphics features through DX11 such as real time GPU tessellation. We set MSAA to 4x and enabled tessellation. Ambient Occlusion was also enabled.
The overclock, even slight, has helped the Powercolor card to remain above the 30 fps sweet spot at all times during our testing. The overclocked HD5850 struggles a little at these settings and the reference HD5850 would need AA reduced for smooth gameplay.
