Introducing AMD’s “Turks” – HD 6670 and HD 6570

S.T.A.L.K.E.R., Call of Pripyat is the third game in the S.T.A.L.K.E.R. series. All of these games have non-linear storylines which feature role-playing game elements. In both games, the player assumes the identity of a S.T.A.L.K.E.R.; an illegal artifact scavenger in “The Zone” which encompasses about 30 square kilometers. It is the location of an alternate reality story surrounding the Chernobyl Power Plant after another (fictitious) explosion. S.T.A.L.K.E.R., Call of Pripyat features “a living breathing world” with highly developed NPC creature AI.

Call of Pripyat is compatible with DirectX 8, 9, 10 and 10.1. It uses the X-ray 1.6 Engine with dX 11, one outstanding feature being the inclusion of real-time GPU tessellation.  It also features a Shader model 3.0 & 4.0 graphics engine featuring HDR, parallax and normal mapping, soft shadows, motion blur, weather effects and day-to-night cycles. As with other engines using deferred shading, the original DX9c X-ray Engine does not support anti-aliasing with dynamic lighting enabled, although the DX10 and DX 11 versions do.

We are using the stand-alone “official” benchmark by Clear Sky’s creators. We picked the most stressful test out of the four, “Sun shafts”. It brings the heaviest penalty due to its extreme use of shaders to create DX10/DX10.1 and DX11 effects. We ran this benchmark fully maxed out in DX11 with “ultra” settings plus 4xAA, including applying edge-detect MSAA which chokes performance even further.

Here we present our maxed out DX11 settings for S.T.A.L.K.E.R., Call of Pripyat DX11 benchmark with 2xAA at 1680×1050 and ultra settings:

The GTX 460 beats its competition but is still too low in the minimums. Next we keep the at resolution at 1680×1050 but drop AA completely and our settings to medium.

This game is still really hard on entry level and mid-range video cards playing on the DX11 pathway. The GTS 450 is faster than the overclocked HD 6670. We would recommend dropping details further if you want to play at 1680×1050 in DX11.
