    From the 2019.2.0a6 release notes:
    What is that and how does it work?

    I was involved in the early consultation on this feature and I don't know how much I'm allowed to say about it so I'll have to be vague, but the key point is that it improves synchronization with the Android display pipeline when rendering. The upshot is more even frame timing and less input latency. As far as I'm aware it should just be an automatic improvement.

    Hello,
    sorry about the delayed reply, I missed the thread!
    We're working on a blog post which will explain in detail what this feature is and how it works, and we expect to publish it during Unity 2019.2 beta cycle.

    Meanwhile we'd like to share a brief overview of the new “Optimized Frame pacing” feature:

    The goal is to delivers consistency of frame rate by enabling frames to be distributed with less variance between them, creating smoother gameplay.

    Optimized Frame Pacing prevents a queue of frames building up by synchronizing the time at which a game submits a frame with the time at which the display hardware consumes that frame. With Optimized Frame Pacing enabled, frames spend less time in the queue, decreasing input latency. The effects of a player's input events are reflected sooner on the screen.

    This is achieved by wrapping rendering calls and employing a variety of techniques which combine the use of APIs such as the Java Choreographer, the Native Choreographer and the EGL_ANDROID_presentation_time GL extension on devices where these are available in order to provide a consistent API from the perspective of the Engine Developer.

    On devices where these techniques are not possible Optimized Frame Pacing will fall back to the original implementations of the wrapped functions, providing no regression of framerate on those devices (i.e. Frame Pacing will remain non-optimal but the code will function as before).

    One more thing to mention is that this feature was developed in collaboration with Google's Android Gaming and Graphics team.

    Thank you for the explanation!

    Is there an API where I can query whether it's supported, like SystemInfo.supportsOprimizedFramePacing or so?

    Not at the moment. What would you like to have it for?

    @jrumps At the moment this is Android only, I'm not aware about the iOS part.

    The "Optimized Frame Pacing" is working like a charm on all Samsung devices I tested on but when testing on a OnePlus 2 device application.tergetframerate is not working anymore. Setting the application to 30fps is not affecting the frame rate.

    When Optimize Frame Pacing Is enabled My Game Freezes After 5- 10 min on my one plus 3T Test Device,For Debugging I Disabled All The Objects From My Scene And Added Just A Plane And A Camera And Deployed The build On Device with auto connect profiler on , And Still With An empty scene with just a camera and a plane the game freezes on the device after 5- 15 minutes , Fortunatily the profiler was connected and In There The Player Loop Was at 60,000ms ,here is the link to my post
    " https://forum.unity.com/threads/and...h-playerloop-in-profiler-at-60-000-ms.863143/"
    here is link on Answers section "https://answers.unity.com/questions/1716017/android-build-project-freezes-after-5-minutes-with.html"
    Finally After building and deploying like 100 time with enabling and disabling player settings I Found That With Optimized Frame Pacing Disabled The Scene No Longer Freezes But When Reenabled Then Scene Starts To Freeze.

    Hi there. I'm a total newbie and have been attempting at my first game since the last couple of months; so, please excuse my nuisance. I'm using Unity 2019.3.2f1 and am loving it.. whilst tryna optimize my game, I tried fidgeting with all the settings and options as much as my brain could assist me. Yup, I'm a total noob-saibot! I miserably failed multiple times (almost 2 weeks experimentation) and got my end result as pathetic as it could've been.
    By now I had all of my textures compressed online and then, crunched under low quality (256) in Unity as well (imagine that view, horrible yeah?).. I dunno how many curses I'd have put on Unity in the last couple of weeks (true story) and was so broken..
    Now, while my game was in that condition, I noticed that my game was kinda lagging. I had Optimized Frame Pacing set to enabled, which did exact same thing as danteswap mentioned above; just that for me, the built was kinda getting frozen after like 10 mins of gameplay; the background music however, continued smoothly.
    Upon every build, I kept getting the warning that Anti-Aliasing is not recommended for mobile devices, asking me to change that under Quality Settings, which ofcourse, is not where AA resides anymore. I'd already selected none under my Camera for AA but had no clue that there was AA option under the URP quality settings as well.
    Removing AA from there fixed everything for me and my game is running like a stallion with 0 lags or any other bugs as such (that under no compression whatsoever). I dunno if this might be of any help but that's what solved my problem and I'm in love with Unity, once again ;) :D :)

    EDIT:
    I forgot to mention that while building, the URP Lit Shader would try to resolve the vertices program which kept showing about 19132 vp which changed drastically to 2436 vp :)
    apart from those, I also kept Dynamic Resolution On with no GI whatsoever..
    As anyone could guess that I don't really know what and how but yeah, my game runs like a charm!

    With Optimized Frame Pacing OFF the game works just fine, so I guess the feature is still buggy / not yet ready for production.

    Got this exact problem. Enabling Optimized Frame Pacing makes the games a black screen after the splash screen.
    Tested on a Xperia T3 (Android 4.4), higher-end devices, works well tho.
    Unity version 2019.3.13f1, scripting backend IL2CPP.

    As an outsider that doesn't have this option ON but maybe would like to, and this thread kinda tells me that I shouldn't, what is the status report on this? Were bugs fixed? Is it more stable now? (I'm not finding anything on the issuetracker)

    I see just a single bug report on Optimised Frame Pacing in the issue tracker, and it's not related to this thread.

    It doesn't seem to play well with on-demand rendering. (I didn't do extensive testing and probably won't as it's not a critical issue to me now; Could also depend on the way it's implemented - I do my ODR checks on Update in case it matters).

    In my case with the render interval at 60 (practically 1 FPS/"idle" mode) the response delay on input is usually maximum (~1 sec until game becomes responsive) whereas with optimised frame pacing disabled the response is instant.
