S.T.A.L.K.E.R.: Clear Sky
S.T.A.L.K.E.R.: Clear Sky is the prequel of the hit title S.T.A.L.K.E.R.: Shadow of Chernobyl; unfortunately it took an obscene period of time and patches for the game to reach a decent standard of stability.
Clear Sky uses the X-Ray engine, the same as the other S.T.A.L.K.E.R. title but has been updated so as to cope with DirectX 10 effects such as volumetric light and wet surfaces.
For benchmarking this particular game we downloaded the official S.T.A.L.K.E.R.: Clear Sky benchmarking tool. It records the FPS for ‘day’, ‘night’, ‘rain’ and ‘sunshafts’. We decided to take the average frames per second of all four at the following settings:
- 1280×1024, default quality, full dynamic lighting
- 1280×1024, extreme quality, full dynamic lighting
- 1280×1024, extreme quality, enhanced DX10 lighting, 4xAA
- 1680×1050, extreme quality, enhanced DX10 lighting, 4xAA
