No pattern to this but the game freezes for up to 20 seconds. It can happen with several scenarios, for example, flying a helicopter, driving, pvp/pvai combat etc. It is extremely frustrating as the game is amazing in every way...however this is limiting my enjoyment. It seems every Xbox player is having this issue in some capacity. Some only have it for two or three seconds, some up to 1 minute!!! It would be awesome if this could be addressed asap as it is currently restricting all Xbox players from enjoying your brilliant game.
