[singlepic id=220 w=250 h=203 float=left]The ExpReview crew have run the S.T.A.L.K.E.R.: Call of Pripyat benchmark on a rig in both DirectX modes to point out that differences do indeed exist.  The shadows look a bit more realistic, and the tessellation in DX11 brings a bit more details to some of the textures.  There’s a slight performance hit for the increase in eye candy, but that’s to be expected.  Check out their results, including nice, big 2560×1600 screenshots.
