The Float32 modification for S.T.A.L.K.E.R.: Shadow of Chernoby has been released this morning, which beefs up the already impressive graphics in GSC Game World's first-person shooter. This mod adds full reflection vector calculations, better bump mapping, real specular effects! All this detail improvement costs nothing in framerate and you will get 20% better framerate than before if not more! Shadows are soft and no longer jagged and the overall graphical quality has been vastly improved.
