Absolute Structures Texture Pack addon - AtmosFear for Call of Pripyat Mod for S.T.A.L.K.E.R.: Call of Pripyat

This texture pack contains edited vanilla textures of man made structures like buildings or vehicles. It also contains textures compiled from various texture packs including:
Ceano's Graphic Compilation
NeilMC's Graphics Pack

All the textures in the pack has been sharpened. This include gradual sharpening of separate MIP map levels in every texture. The benefit is that the usually blurred MIP maps are still sharp as they fade into distance. This results in overall sharpness of the image.

Most of the textures are the same resosution as vanilla so they don't require much more RAM to load. You can use them even on low spec machines.
