I’ve tried everything restoring, changing settings, adjusting display options, and switching cables. My take is that it’s too slow for 4K for some reason. To be honest, even my iPhone lags sometimes. Either it’s an OS problem (which is possible) or the hardware is subpar.Glad that’s not just me, I notice the lags and stutters all the time.
I feel like Apple has allowed too many APIs, wrappers, and non-native software to run on iOS, tvOS, and iPadOS instead of enforcing stricter requirements for Swift or Objective-C. When I exit YouTube, I get around 20 FPS. Switching between Infuse and Pluto TV lags terribly.
This has been my experience since day one, but my initial impressions were good because I was coming from an Amazon Fire TV 4K Max and Google TV both of which are miles behind in terms of speed.
