Since the last update I’ve noticed some low frame rate problems. It is extremely noticeable when you press the back button to see the leader board. However, today it is extremely noticeable to the point that it made me sick. The game is being supper choppy and skipping frames so bad that my brain couldn’t take it and now my stomach is suffering the consequences.
Hey OP, 343 are currently tracking frame rate issues here
