Gaussian Splat low performance on iOS devices vs Android

Questions

Hi,

We are experience gaussian splat rendering lower performance on iOS devices compared to some Android devices he have at hand.

As an example, the first model on this PG (the parrot) we are having:

30-40 fps on an iPhone 15 pro

30-40 fps on iPhone SE 2nd gen

60-80 fps on Samsung S22

60-120 fps on Samsung S24

Is there any known limitation on iOS devices that keeps the fps at that range?

Thanks
