I'm building an iOS/iPadOS app for iOS 18+ using the new RealityView in SwiftUI. (I may add visionOS, but I'm not focusing on it right now.) The 3D scene I'm rendering is fairly simple (just a few dozen vertices and a couple of textures), and I'd like to render it at 120fps on ProMotion devices if possible. I tried setting CADisableMinimumFrameDurationOnPhone to true in the info plist, but it had no effect. The frame rate in the GPU Report in Xcode stays capped at 60fps, and the gauge even tops out at 60.
My question is kind of the opposite of this post, which asks how to limit the frame rate of a RealityView.
I'm on Xcode 16 beta 5 on macOS Sonoma and iOS 18.0 beta 6 on my iPhone 15 Pro.
