Low frame rate on new iPad Pro

I have noticed lag and low frame rate (30-36fps) in ARKit apps built with Xcode 11.4 on the new iPad Pro (12.9" 4th gen). Exisitng AR apps from the App Store and AR QuickLook work as expected. The same apps built with Xcode 11.4 run well on my iPhone XR. For an example, I ran the RealityKit template app with no modifications on each device, and the iPad has anywhere from 30-36 fps fps while the iPhone stays constant at 60 fps. Is anyone else experiencing this issue? Thanks!

I am experiencing the same issue. Perfectly smooth on an iPhone XS and regular framedrops when adding new nodes to the scene on the 2020 iPad Pro.
