    Hi


    Is the adaptive sync subject to only Apple Apps and iOS or do all the apps automatically take advantage ?


    Excited to see that the new iPad Pro's are 120hz, and you can really see it on the demo machines on the main screen, but are the apps taking advantage of it? The game demo i tried (cant remember the name), it didn't seem as smooth. Wondering if they need updates to take advantage. Hopefully the new iPhone 8's will also be 120hz. Looks like they will be. Fingers crossed.


    i like playing Zen Pinball on my 144hz gsync PC. The ball glides perfectly smooth across the table in 144hz. However if i try and play that game on a 60hz its horrible, and it may of been ok PRIOR to ever playing it on 144hz gsync, but once you've had gsync, its hard to go back. Your eyes really pick up on lower refresh rate and it just no longer feels right. Same deal on the iPad (non pro) icons just no longer glide smoothly across the screen, once you've used a 120hz pro. But if its not being taken advantage of in the apps and most are frame rate locked at 60, then i'm not sure its worth the extra expenditure.

    Apps don't specificly taking advantage of it, it's the iPP that's doing it automatically. If there is motion the screen will show it 120Hz, unless it is fixed (like in a video file)

    Not sure you quite understood the question.

    Of course i know its the iPad doing it. The new iPad specifically. Most most code is written with locking in the refresh rate in mind. Because 99% of iOS devices cannot go above 60hz or 60fps i'm fairly sure that not many apps are taking into consideration the new capability of going to 120hz. If they were frame unlocked, we would see tearing on all our old devices.

    Anyway guess i answered my own question. Hopefully once the iPhone 8 is out, and if it has a 120hz, perhaps the app devs will send out updates. But given its not going to be noticeable by many, im guessing it will not be on their high list of priorities.

    I don't understand why you'd expect simple apps to lock their frame rates in coding. Most apps have only UI animation and those are only limited by the screen's refresh rate, not a line in the codes.

    You can have various implementations of V-sync to avoid tearing. Most games will still only run 60 fps at best due to supporting older models as well as performance considerations. Honestly it's fine, I don't really see much improvement for those purposes in going above 60 fps and I have a 144Hz desktop display. On the desktop you can mostly notice it in less blurry scrolling and more responsive cursor and the iPad Pro does the scrolling bit just fine.

    Most developers would code in time not frames. So you would code for an animation to take 1 second moving from X to Y. On older iPads, this would display 60 frames of animation in 1 second (unless the game or app was causing FPS issues, but lets ignore that). On the new iPad, there would be 120 frames for the animation. Same time for the animation to complete, but more frames which makes it look smoother.
