I still think everything looks "bigger" or "closer". My gunnery is off as well but I believe it is a matter of perception.
My normal problem is not leading enough and now, surprisingly, I've found myself shooting in front of targets in turns more than once.
As the gvers have complained as well, I think it will just take some time to "get used" to it.
Otherwise, I don't think the gunnery model nor lethality has changed at all.
Everything is BIGGER and clearer.
