There's little doubt that the Xbox 360 is the cleaner, crisper experience and for the most part it commands a small but significant frame-rate advantage and fewer little glitches; especially outside of combat scenarios, the game just seems to run that much more smoothly.
However, there are parts of the game that seem to be brutally unoptimised, bringing the performance level crashing down to the point where the afflicted sections become almost unplayable - a variable 15-20FPS update in an intense fire-fight is hugely disorientating, and this makes Crysis 2 one of the most inconsistent performers released in recent times.In these situations, it seems that it is the Xbox 360 version that has the most difficulties, though there's no mistaking that both platforms seem to lag badly in much the same areas. Interestingly, the really poor-performing sections do seem isolated to specific areas in the campaign, and from the hive infiltration level onwards things seemed to improve, but it's quite difficult to believe that those areas of the game got through QA without someone, somewhere raising the red flag.
