Xbox One Microstutter on Arcade Mode and Starfighter Assault

Not sure what you mean by Microstutter?  Are they just small freezes where everything stays in place or are you getting rubberbanding (enemies move, then magically reset back to where they were moments before)?

I was having severe rubberbanding issues when using my Xbox on wifi.  Once I switched over to hardwired the issues went away completely.  Not ideal, but if you are on wifi, perhaps you could try switching to a hardwired connection to your modem/router and see if it helps.
