According to this 2K forum post made by 2K community manager Elizabeth Tobey, the publisher’s going to patch the PS3 version og BioShock to get rid of some unwanted graphical quirks.
The game’s out on Friday.
From the post, two issues will be dealt with:
Big Daddy Bouncer and Elite Bouncer textures appeared pixelated
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.
More through there, including comparison shots between the PS3 and 360 versions.
