We have an XBOX One, two XBOX One S, and one XBOX One X.
Anytime the XBOX One X joins a game hosted by the other 3 the player is skipping around which makes it impossible to play. If the XBOX One X player hosts a game then the others experience the skipping in game.
Seems to me like a version conflict?
xbox one x here split screen causes my entire game to drop frames harder than a Vegas hookers panties. especially when either player opens their inventory
Yeah we seen that issue in splitscreen coop.
I believe the video lag is causing the skipping, stuttering, rubber banding in coop between different consoles. When the FPS is balanced between all consoles connected then it goes away.
