On macOS 13 Beta with Xcode Beta 4, I'm unable to use the ARView Rendering options described in the documentation:

https://developer.apple.com/documentation/realitykit/arview/renderoptions-swift.property?changes=latest_major

They simply don't exist on the ARView class. How can we disable rendering effects on macOS? A simple cube uses 1GB of memory which is a bit ridiculous.

Furthermore, there should be a way to control the frame rate of the view. It's forced to 120hz on my Macbook which is way overkill.

When reverse engineering RealityKit, I can see that there is a variable there:

RealityKit.ARView.__preferredFrameRate.getter : Swift.Float

But it's private. Any plans to make this a public setting?

It looks like you can call the frameRate setter anyway, but it has no effect.

arView.__enableAutomaticFrameRate = false
arView.__preferredFrameRate = 60

Hi, it's a known issue that renderOptions is not available on macOS (86489892). However, all of those render options should be disabled on macOS anyways. Regarding __preferredFrameRate, that value is ignored on macOS and the frame rate of your app is set to the frame rate of the display. It's also a private API so you should not use it. You are welcome to file an enhancement request on Feedback Assistant for this functionality.
