Ever since the Hotfix 1.14.60 came out,there has been studdering lag while playing splitscreen on the Xbox One. It appears to happen every 15 seconds or so,and is most noticeable when placing/breaking blocks,flying an elytra,or running. It seems to have short periods where it operates great,and then starts to studder again. Turning down settings for render distance and simulation distance do not appear to help. It makes it somewhat frustrating,and hard to play.
