Do you limit the display framerate to 60 Hz?

  • I haven't. I find that in iOS12 graphical performance has been much optimized compared to iOS11.

  • What was wrong with the frame rate before? I was using the 10.5 and never bothered lowering it cause I didn't notice any problem at all.

    I assume that @tja was worried because of the significantly increased graphics workload when at 120 Hz, which might affect realtime (audio) performance... if I were able to afford such an iPad ;), I would probably limit the framerate to 60 Hz as well just to be safe. Is there really a huge noticeable difference between 60 and 120 Hz? I mean, I have extremely fast visual perception, but around 50 or 60 Hz I stop noticing the individual frames.

  • I haven’t had any problems. I honestly can’t stand looking at the iPad without the 120hz refresh lol. Makes everything feel so fluid

  • When nothing on screen is moving, Pro Motion automatically drops the frame rate from 120Hz in order to save processing power, and battery life.

  • Would this improve battery life?

    Well, if you were drawing using Illustrator or Affinity Designer, trust me, you would see the difference. At this framerate it's like drawing on a paper sheet :)

    hm, is the display frame rate connected to touch input latency?

    I doubt you'd be able to notice a difference of 1/120th of a second.

    Not so fast (pun intended)! :) that's roughly 10 milliseconds, and for example many keyboard players find that much latency atrocious... so if touch latency is indeed linked to display refresh rate, then 120 fps might actually make sense for live music app use...

    Very roughly... only 8ms, actually.. and that's the maximum latency.. on average you'll only get half of that, so the difference is not nearly as dramatic as you're making it out to be B)

    so display refresh rate and touch input latency are connected?
    or they aren't ?

    CORRECTION: They apparently are...

  • I have been limiting it, and it still does make a difference on 12 for me, less cpu spikes when pushing the ipad to the max when at 60hz.
