I'm not recognising the input lag people are talking about. Yes, sometimes I notice with normal dribble the player is not responding to my change of direction that very split second, but the player pushes the ball slightly ahead each time and he's just not is complete control of the ball for that split second the ball is away from him, and it can cause you to over run it. Seems perfectly natural and real to me anyway. The ball is a lot freer now also. I'd worry if they did something about this that it might make dribbling a little easy.
I'm not noticing the floaty airbourne shots anymore either. I did when I started playing the demo. I think alot of that has got to do with the way the camera is moving. When you take shots from out side box, the goals aren't in the camera frame. When you kick a powerful airbourne shot, the camera follows the ball until the goals are in the frame and then slows down and stops while the ball is still moving fast. The way they've coded the timing of the camera slowing down and stopping while the ball is still moving fast may have an odd optical effect of making the ball appear to slow down, hence the floatiness. I can't say that for certain, but the shots seem natural to me now and not floaty, as I've obviously gotten used to something in whatever way that is, so this was just a stab at possibly trying to explain it. Don't quote me on it.
I've noticed the defender catch up people are talking about. The CPU only seems to be able to do it though. I was sprinting at full pace down the wing with one of the Italian wingers, and Mertesacker of all people came running after me like he was being chased by a nest of wasps. He caught up so quickly. The speed he ran looked ridiculous for him especially to be able to do. I've noticed I can't do this though, when I'm defending and chasing the attacker. The players though, on the ball do naturally slow down when they are keeping control of the ball when sprinting, which is realistic and shouldn't be touched I think.
