It seems that the WWDC20 Ray Tracing examples need a Intel Skylake GPU or above, the Skylake was included in MacBooks released in Early 2016. But the Ray Tracing examples do not seem to work with the Intel Xeon W in the iMac Pro and also the new Mac Pro 2019? The Mac Pro is Apple's most powerful machine, surely the Intel Xeon W should have enough power to run the Ray Tracing examples? When I try to run the sample below I get the error "Ray tracing isn't supported on this device".

The new RealityKit 2 ECS enhancements from #WWDC21 are awesome but to learn them I need a simple example! Could someone please post a simple RealityKit 2 ECS example that rotates a simple cube using a Rotate Component? If the Rotate Component is added then the cube should rotate. If the Rotate Component is removed then the cube should stop rotating.
