As soon as I start playing on a Conflict server, the game consumes an incredible amount of bandwidth.
When I play Conflict, no other person in my household can use the internet connection. The connection becomes very jittery due to the game. Immediately after quitting the game, the connection is fine again.

Normally, when I play a game online (e.g. DayZ), the bandwidth is not strained at all.

Im playing on SeriesX.
