Anyone in denial about the real-time nature of Konami's Metal Gear Solid 4 trailer should watch this older, but recently YouTubed video demonstrating the attention to detail and graphical clarity of the MGS4 engine. In it, the narrator plays around with the demo on a PS3 dev kit, covering all the neat graphical tricks Kojima's team uses, including uber-high polygon counts, depth of field, and high dynamic range lighting. It also has pee jokes. Fascinating stuff.
