In previous versions my iPad could maintain stable at 60 fps for a long time, after updating the new beta version, when flying, the frame rate randomly decreases to 30 fps for 2 min and goes back to 60 fps, and doing multiple reps like this. My display settings are 60fps, and no, it isn’t device overheat, and the device wasn’t charging.
Same here star with 60fps and go down to 40 and 30fps. They done great job optimising with Apple silicon no heating anymore running really smooth now. Only need fps to stay stable at 60fps.
We are experimenting with a new frame pacing algorithm on iOS which results in more conservative frame rate so it remains consistent instead of being very “spiky” (stutters)
A smooth 30fps is usually much better than a stuttering 40-60fps
Note that the graphics setting only controls the maximum the system will try to reach; if it detects uneven frame-rates, it will automatically lower to the next target frame-rate that is a multiple of the display refresh rate (60->40->30 on ProMotion displays, 60->30 on the other ones)
We are still working on optimizing our new metal backend so we can maintain stable 60fps in more cases and will continue to iterate on this frame pacing system.
I’m seeing the same thing. I normally keep mine at 30 FPS, but I’ve been getting FPS drops with the latest build too. I tried switching to 60 FPS for the first time in ages, and it actually runs much smoother now and stays at a pretty stable 30 FPS. I still get the drops when it’s set to 30 FPS though.
