Well i have the PC version of the game... running on a high end PC... and it looks very good... better than any of both version (ps3 or x360) But... after playing the ps3 vesion for a while i noticed that everything on the game looks just as good as the x360 0 lag it works like charm... if these games could run on a highest res, i'm sure that it will looks almost as good as the PC.
Bioshock has poor graphics.
