Don't worry. Not that kinda in game loading, he means the loading to get the level ready. But those load screens do take there time, other than that great game just beat it yesterday. also not sure about igns supposed frame rate issue beat the the game, no issues.
They were talking about cut scenes which after a couple missions I noticed once briefly. Like I said the screen tearing they mentioned on 360 and PS3 is far worse, which you can very obviously see just from watching a couple of YouTube videos.
