The funny thing is the arguments have been had about Motorstorm and here they start again. If MS wasn't rendered it would have been stated to they same degee that MGS4 was in real time. Also although MGS4 was impressive graphically its nowhere near the MS video. Finally EDGE uncovered this "As for Motor Storm Sony claimed it was made using assests created by the developer Evolution studios. Edge however beleives the sequence was made entirely by CG specialist Realtime UK. "Neither the Sony or the Studio were prepared to reveal details. This issue arrises bacause, based on previous working methods, it seems lilely RealtimeUK would authored all assests in house. If this was the case it would make the description of the footage as game demo as an extreme exercise in being economical with the truth. Again don't expect this quality from launch games."
It's rendered simple as that.
