Some of you who've played the BioShock demo may have noticed a number of minor graphical differences between the PS3 and 360 versions. A 2K community manager by the name of 2K Elizabeth made a post on their forums about an upcoming patch that will fix some of those problems, specifically:
Fix for an issue where large blocky pixels would show up whenever viewing the Bouncer and Elite Bouncer variants of the Big Daddy.
Fix for an issue where white/discolored bars would show up at the right and bottom sides of the screen during the plane crash / water scene at the beginning of the game.
There are other problems fixed, but the full patch list will be unveiled at a later time. The patch itself will be released some time after the game's launch, but no specific date has been announced.
