You just have to put this code "-dx9" in your launch options (Right click on Bioshock and select properties in steam and go to "set launch")2- About the problem with windows 7,you can change the game compatibility, choosing Windows Vista and making right click on bioshock.exe (you can find this file on steam folder)3- Change the video card config. Nvidia have a lot of default settings, like high textures and buffer things. Try to disable those things.
