Are you proposing that iOS might be so broken it's impossible to flawlessly copy a handful of screen-size rendering buffers at 120Hz? Because if you can do that, then it's possible to make a flawless no-lag non-native 120Hz UI.

I don't know if you can even access the screen at such a low level on iOS, I think for sure you'll have to go through a middleman to get pixels on the screen.

Sure, you have to go through a middleman. Does the middleman stop you from copying a texture to the screen?
