Online seems to be a mess of internation connections, from europe, the uk and the US....these different levels in connection qualities is leading to lag in the game, and more importantly....poor hit detection
For example, on your screen you see you put a full clip into someone, only for them to turn around and either shoot you quickly or melee you and your dead. Viewing the Kill cam will then suddenly show that from the view of the person you thought you should have killed...none of your shots hit him and you werent even looking at them
Patience, hopefully Crytek is taking this kind of feedback and issue seriously, as well as other feedback, and will introduce a Region Filter for connections so the US will play the US and Europe will play Europe
