We can't recall hearing this before, but News4Gamers.com is reporting that the graphic engine for GTA IV is actually the same RAGE engine used in the recently released Rockstar Table Tennis.
An excellent choice. RAGE is known for its excellent fluid physics. In Table Tennis, this can most obviously be seen in the way the beads of sweat realistically spray off the foreheads of the players. Imagine an opalescent string of pearls realistically jiggling upon the neck of an avatar and you will understand the full potential of this technology when applied to GTA IV... and, more specifically, it's forthcoming mod, 'Hot Coffee with Milk'.
