The anti aliasing settings shown here work in most of the games. So its not limited to Bioshock at all. Just install the inspector tool and edit the particular game profile, apply the changes and start the game.
I use a GTX 580 so SGSSAA 8x is fine. Remember to set Multisampling at the same setting. So if u choose SGSSAA 4x it has to be 4x Multisampling and so on but dont forget to toggle FXAA on.
