People canceling preorders after PS3 demo
* The game runs at sub-720p, but forces itself to display at 1080p instead of defaulting to the game's optimal resolution like other 720p games. Thus you have to manually change it to 720p in the Display Settings or you'll get nasty white bars on the bottom and right side of the screen during cutscenes, which ruins the immersion factor of, say, the underwater cutscene at the beginning. And frequently during play, traces of this white garbage will appear and linger on the outskirts of the screen until you pause the game. Terrible.
* Many textures are a pixelated mess. Look at the dead Big Daddy up close; the textures are big, blocky pixels, like something out of a PS1 game. Or try pushing in the right analog stick (R3) to zoom behind the pistol, and look at the blocky mess of pixels on the barrel of the gun. Look at most walls. It hurts the eyes and in the case of the Big Daddy it hurts the heart. How could this happen to such an iconic character?
* The framerate jitters along, especially during the submarine sequence. Look at the windows on the hive towers of Rapture as the bathysphere makes its descent; look at the stop-motion animation of the squid as it darts by; this lack of smoothness is distracting and steals the scene's power.
