Plus, the difference is quite huge. Pause the video at any given moment and u will see things like:
-weapon in 360 version is blury while in PC is perfectly crisp and clear
-a LOT of shadows missing in 360 version
-a LOT of objects missing in 360 version (caused by the extremely low draw distance, that causes the pop ins)
-the textures are actually quite a lot worse on 360 then on pc and it's most apparent in the bathroom footage (and not only)
-lighting seems to be way WAY worser on 360. Things like light bulbs not casting light on near by objects, no volumetric light at all, "god rays" toned down a lot etc.
-probably the most important thing that everyone seems to be missing: 30 FPS @ 1152x720 res on x360 VS 60+ FPS @ 1680x1050 res on PC
All in all, pc quality is better by quite a lot. But still, it could've been so much more. Maybe full version will have an "enthusiast" setting and maybe some dx11 features to go with it and crysis 2 will be once again crowned the king of PC.
