Xbox One laggy/jerky movement

Hi all,

I bought the game a few days ago and so far on every map I've played I've experienced weird laggy/jerky movement. It happens all the time, but is most noticeable when running - for every, say, three steps that my soldier runs, he is momentarily 'pushed back' or slowed considerably. It's incredibly frustrating and is making the game unplayable.

My connection appears to be otherwise perfect in the game, with other players not exhibiting any strange behaviour, and my blaster shots always hit (or more often than not, miss) their target in a way that makes sense. My connection bar is full, my NAT is open, and I've tested my Xbox Live multiplayer connection and it's perfect. All other online games I play (Rainbow Six: Siege, PvZ2, Evolve, Payday 2) work perfectly.

The only thing I've tried so far to remedy the issue is port forwarding, but that hasn't worked. Given the fact that my connection shows no other issues, I'm wondering if this even is connection-related. But at the same time, I can't think of anything else that would be causing my character to move in such a jerky, inconsistent way.

Thanks in advance for any help.
