After playing the game for a long time (on the XBox 360 only), the game begins to "hitch" or "pause" slightly every 10-15 seconds. The problem does not go away if you restore a savegame, start a new game, or reboot the XBox 360.

Solution/Workaround:

This seems to be a problem with the hard drive caching system on in the XBox 360 system software, and we are working with Microsoft to identify a solution for this issue. We have confirmed that the hitching goes away if you clear the hard drive cache.

To clear the hard drive cache, you must hold down both the RB and LB gamepad buttons while the game is starting. This must be done IMMEDIATELY after the console is rebooted (or the game is launched from the dashboard) and the buttons must only be released AFTER the red 2K Games logo appears.

So do that and your shuttering/freezing should be solved.

-------------------------------------

After your plane crashes into icy uncharted waters, you discover a rusted bathysphere and descend into Rapture, a city hidden beneath the sea. Constructed as an idealistic society for a hand picked group of scientists, artists and industrialists, the idealism is no more. Now the city is littered with corpses, wildly powerful guardians roam the corridors as little girls loot the dead, and genetically mutated citizens ambush you at every turn.

And as for widescreen, we also want to say we completely understand a user's desire to augment their FOV. BioShock is a harrowing experience, but we don't want anyone to feel limited (or motion sick!). So we are in the process of working on an official PC patch to give widescreen PC users a choice to expand their horizontal FOV, and are investigating creating a similar update for the 360.

Starting immediately, we will be upping the activation count to a 5 by 5 plan. We will be raising the maximum amount of computers a user can have BioShock installed on simultaneously from 2 to 5, and allowing a user to reinstall BioShock on each of those computers from 3 times to 5 times. Also, we have in the works a revoke tool which you will be able to run on your machine if you want to free up that key and move it to to another computer (this works very much like Steam or iTunes system). We are also working with SecuROM and 2K customer service, so that when you do need to call in support problems, you get answers to your questions faster, without much waiting or being bounced around. SecuROM has been given much more autonomy to help fix your problems quickly and effectively. I am personally sorry for anyone who got bounced around in the past couple days (I even think I contributed to this problem) and we're going to make sure that does not happen in the future.
