I just noticed the 1up review:
http://www.1up.com/do/reviewPage?cId=3166819&p=4But despite the interesting narrative and excellent sandbox experience, the 360 package is somewhat spoiled by the less-than-stellar performance of the graphics engine itself. The framerate is erratic and dips every time the game loads a new area. This is particularly noticeable when leaving the confines of Bullworth Academy for the surrounding townships. Another distraction is the inconsistent visual details of the in-game world; while a significant amount of time was obviously spent sprucing up the school campus with high-res textures and models, the rest of the world runs the gambit from merely bland to absolute eyesore. There's also a significant amount of pop-in every time the camera moves quickly around the player. Perhaps worst of all, we had several instances where the game froze midmission, and since you can't save at any moment it sometimes necessitated replaying a significant amount of the game. It's really a shame that these technical problems detract from what is an otherwise outstanding experience.
