can't even fathom how this game will look w/ the iCEnhancer mod if they can make gat iv look like this:
Real textures, or rather pictures (Textures with little depth, transparency, and has angled, pre-existing lighting and shading.) placed in the game like this can make the game look real in certain places, but it only seems to work well on relatively flat surfaces (Which, in turn, makes the reflections look realistic on the car.), and tends to highlight other issues with the graphics. It almost looks like a real picture was pasted onto the background.
As soon as you introduce somewhat complex geometry, animation and other graphical effects, it tends to fall apart. I think one of the main reasons why it worked so well with GTA IV is because of the simplistic geometry of the city, or specifically, the buildings.
