I can only speak for PC here but it likely applies to Xbox One too. If you're talking about the stuttering that I think you are then that is server side and generally very common in the game. I'd imagine the issue extends to Xbox due to the nature of it. They've tried other servers too but it's clearly either their netcode or the simulation itself as nothing so far has fixed it, or should I say nothing had fixed it when I last played about a month or so ago.
I have the linux version, and only a 750ti. So I can If I set the game setting pretty low I actually get similar frames to what the frame counter in this video shows. It can dip to single digits often. However I don't get that crazy stuttering.
Altho now that you mention it, I think I have run into that network hiccuping while playing and I recognized it as such. If that's what's happening in this xbox video then that makes it look worse than it is.
If I play this game at low and medium settings, it runs about 20-25 fps at around 720p. I know that's unacceptable to many posters here but that's good enough for most people who want to play a fascinating and fun mess of a game.
My gf loves this game even tho it looks like ps3 and runs like n64 on out syetem. She perceives nothing negative about the performance. INTERESTINGLY, she can tell that it looks much better on a 970, but that doesn't ruin it for her.
