Update: That could be the PC version with a 360 controller, due to the fact that the comparison video on GameVideos doesn’t show such great differences.
Original Post: A user of the Giant Bomb forums has done an image comparison comparing two shots of BioShock. One of the shots is on the PLAYSTATION 3 (left), and another of the shots is on the Xbox 360 (right). As you can see, there are very shocking differences. The PLAYSTATION 3 really looks a bit washed out, and I’m very disappointed to see that.
