I think RealityKit and RealityComposer use SceneKit under the hood for rendering anyway. I doubt they would re-invent the wheel. But maybe I am wrong and Apple uses Metal directly to render in RealityKit and RealityComposer. It would be interesting to have a confirmation by an Apple engineer on this forum.
