Using Snapdragon Enb [tweaking it on different lighting conditions]. Using High DOF [turn down the environmental texture to 1k [large objects] - 256 [small objects] "mixed". Whats the point if its 4k if its blurred anyway, give performance boost]. 4k - 2k on the skin textures, main attraction.
@pussy69 Its simple to mod [drag & drop files/replace], easily accessible [no "unpack-replace-repack game assets" when installing mods] and most of all, modders shares Ideas [even they don't openly says it, its obvious by studying there work, you'll get the Idea]. If you have an high-end Rig you can Crank up the graphics way past the game specs. :-)
Only the bad this is if you play it in vanilla. :p
@over soul Example, RAW. Scrapped, forgot to Tweak the Snapdragon ENB effect using PS [-50 brightness, +50 contrast]. The Size of that thing. Its a 4 sec loop at 165+mb. So, nope. http://www3.zippyshare.com/v/knvSqy1r/file.html
