As you may already know, the incredible action game that is Bioshock requires pixel shader 3.0 support in order to run. There is no ps2.0b mode, thus, the game will show major graphical problems on the ATI Radeon X800 and X850.
But, all hope is not lost yet! A couple of motivated people are working on a fix for we who own the best video cards ever designed. Think Oldblivion for FX video cards, but in Bioshock and for X800/850. It's still far from perfection, but, what, 2 weeks after the game's release, it's already an impressive effort.

EDIT: here's a petition to Irrational for adding 2.0 shader support in a later patch. At the time of writing this, above 4700 people have signed it. http://www.petitiononline.com/BioShock/petition.html
