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.
S.T.A.L.K.E.R.: Call of Pripyat utilizes the XRAY 1.6 Engine, allowing advanced modern graphical features through the use of DirectX 11 to be fully integrated; one outstanding feature being the inclusion of real-time GPU tessellation. Regions and maps feature photo realistic scenes of the region it is made to represent. There is also extensive support for older versions of DirectX, meaning that Call of Pripyat is also compatible with older DirectX 8, 9, 10 and 10.1 graphics cards.
The game S.T.A.L.K.E.R.: CoP has no internal benchmarking tools built into the game engine, but they do have a standalone benchmark available that we used for our testing purposes. The screen capture above shows the main window of the benchmark with our settings. Notice we are running Enhanced Full Dynamic Lighting “DX10” as our renderer. Under the advanced settings we disabled tessellation, MSAA and ambient occlusion.
S.T.A.L.K.E.R.: Call of Pripyat looks to only be threaded for one CPU core as you can see from the Windows Task Manager screen capture that was done during a benchmark run.
Benchmark Results: S.T.A.L.K.E.R.: Call of Pripyat is fairly tough on systems and we discovered that the Intel Core i3-2120 and the Intel Pentium G620 both have nearly identical performance numbers. Since there is a 500MHz CPU difference between the processors we can safely assume that the performance bottleneck is from the GPU. Both processors run the Intel HD Graphics 2000 series GPU and that is the culprit. The Intel Core i3-2105 uses Intel HD 3000 graphics and is much faster in than the Intel Core i3-2120 in 3D gaming scenarios.
