When I run a WebGL app built with Unity 2021 3.10f1, it runs slower on iOS 16.1 devices than it did on iOS 15 to iOS 16.0.
And we have heard from many players playing with this app that it runs slower on iOS16.1.
The problem is that the screen often freezes for a moment when loading assets.
Is anyone else experiencing this same problem?
I would like to know if anyone knows of a solution or reference for this.
Devices that have been confirmed to be running slow :
I don’t know about the slowdown on iOS 16.1, but WebGL only runs single threaded, so it always freezes when loading assets.
Please see the discussion below.

I was facing the same problem. In my case, I experienced a 3-5 seconds freeze when displaying dynamic font texts on iOS 16.
Changing the font to Custom Set work around the problem. There may be a problem with writing textures on the new Metal backend…
I am also having problems with dynamic font text, which I am still facing with iOS 16.2.
Does anyone know the status of Unity’s or Apple’s response to this issue?
