X800 users: Warning
BioShock apparently does not support x800 and earlier video cards even though they are more powerful than some later cards. There is an ATI hotfix that is supposed to cure this and is 97mb in size.
The ATI hotfix does absolutely nothing at all but waste your time. It will not fix any problems. If you have an x800 video card, you will not see a cursor in game menus and will have almost zero visuals rendered in the game. The game is completely unplayable to you right now.
If you set your mind on trying to get the game to work, get ready to have to sit through exactly 9.57 hours of 2K introduction graphics to the game, followed by an NVidia advertisement. Only one introduction video can you skip, the other 19 you have to watch. Remember that you have to sit through these videos every single time that you restart the game, because 2K has to remind you literally upwards of 50 times (that's seriously not an exaggeration) that 2K is the developer of the game that you cannot get to work.
x800 users, do not purchase this game until 2K gets their act together and makes the game support graphics cards that were new 1 year ago. If I can run Oblivion on 'very high settings' I should be able to load one pixel of the surface of the water in the beginning of the game.
