playing project gotham with component video 480p in the garage and on some tracks i notice image "pop in" kind of like the way progresive jpegs come into focus...
ive only noticed it wiht this game so far and have yet to try it in HD...
it seems to do it once then never happen again in that game session.

can any one confirm this?

This is a bug they tried to minimize in the last stages of game developement, it probably happens very rarely and has nothing to do with 480p. From what I've heard Need For Speed is much worse for pop-up.
