Bingo - there's no way to circumvent it except:
1) Downgrading the OS (on devices where they even allow it)
2) Downgrading the device (for cases where they don't allow downgrading OS, but that beats the purpose for gaming)
I've been buying iPad Pros for gaming for many years and I've never, ever seen this degree of bullsh* before. Fortunate for you if it's still playable, but for me on the M2 iPad Genshin is total mess thanks to this bug and I know it could run perfectly smoothly if it weren't for ProNonsense because when 16.2 landed it worked well for everyone for a day or so, during which I stress tested the iPad to near-meltdown repeatedly and suffered no lag at all. And I can't go back to M1 because M1 lagged genuinely due to not being able to run it well enough (while M2 can).
Simple test for anyone who wants to see the difference:
Leave ProMotion on and use an iPhone 14 PM or an M2 iPad, then open Clash of Clans (an undemanding game from 500 years ago) at default settings. Then take an iPhone 11 or 12, open the same game. Zoom in on both devices, and try scrolling around the screen. Night and day.
