I am very confused by these claims on M1's GPU performance. I build a WebXR app at work that runs at 120hz on the Quest 2, 90hz on my Pixel 5, and 90hz on my Window 10 desktop with an RTX 2080 with the Samsung Odyssey+ and a 4K display at the same time. And these are just the native refresh rates, you can't run any faster with the way VR rendering is done in the browser. But on my M1 Mac Mini, I get 20hz on a single, 4K screen.

My app doesn't do a lot. It displays high resolution photospheres, performs some teleconferencing, and renders spatialized audio. And like I said, it screams on Snapdragon 865-class hardware.
