I haven't been playing too well so far (only had it 2 days, played about 3 hours total), but getting better.
Mine also seems super laggy sometimes. Even when I die, supposed to click Square to respawn - it doesn't register the click for a few seconds. And if I hit start to view the map, it takes a second or 2 for it to come up and then the same for it to go away. Not sure whats going on.
