Console or computer? On some consoles, the graphics are dumbed down because the hardware can't handle it, or doesn't support some stuff, like DirectX 11, which Bioshock 2 is heavily compatible with. For instance, the entire Need for Speed series looks way better on a computer on full settings compared to a Playstation 2 of the same age. I have played Need for Speed: Undercover on a Playstation 2 with 720p resolution on a 25" screen, and it looked overly blurry and lagged, while my 2008 HP laptop with a 1.6 GHz single core AMD and a very low-end ATI graphics card can play the same game on medium-low settings with it looking crisp and smooth at 720p.
