Something to look into:

My card does not support Pixel Shader 3.0. As such, I can't run Bioshock without everything looking like black squares. I can't even switch on the shaders in this game, but the descriptions of the errors people are saying.. well, they sound familiar.

Perhaps you guys accidentally implemented Pixel Shader 3.0 without putting in 2.0 support?
