I've noticed when I'm playing with live, turn enabled players, the swing animations for their golfers can be a little choppy as I'm watching them play their shots. When I'm playing my shot, I don't see any choppiness though.
The only performance glitch I see is maybe two or three swings per round, my golfer seems to be reluctant to start the backswing when I pull the swing stick back. When that happens, I let go of the stick as soon as I realize I haven't gotten an immediate response, and start the swing over. It never fails to go off smoothly the second time. I should add that I'm playing on an XBox One X, and that may have some bearing on the difference in our experiences with it.
