I have had a great experience thus far with my 10.5 picking it up months ago back when it was still running iOS 10. I'm not much of a gamer but recently decided to pick some games up from the app store. Whenever I go to the home screen after playing a game the multitasking menu will pause for like 1-2 seconds, same goes for when I swipe up when I'm still in the game. This doesn't happen with any other kind of apps just games. I'm running the latest iOS 11.2 so hopefully this is a bug i can help make aware of and gets fixed in a future .dot update.
