The Division’s Update 1.4 is now available, but unfortunately players on Xbox One have to struggle around with stuttering issues on their consoles. According to a new post in the official forums, the problem has something to do with the game’s voice chat.
Because of that and as a temporary solution, the developers have decided to disable it only on Xbox One to improve the gameplay experience at least a bit.
This means that you will no longer be able to use the voice chat in game, which includes group chat and proximity voip.
Of course they are currently working on a permanent solution, but no further details on when this feature will be back have been stated. Stay tuned for more information about it.
