First OpenXR headset rendering on macOS 🎉

@ShinyQuagsire That's really cool! Are you running it on an ARM mac or an Intel one?
@foreverandaday this is the 2021 MBP so ARM64 (probably works fine on Intel too though)
@ShinyQuagsire Interesting! I'm not super familiar with the gpu capabilities of the ARM macs since there's not many games that run on them. Like I've got an m1 mba but I have to game on my desktop or steam deck. At least from an empty void it seems to be doing pretty well though!
@ShinyQuagsire oh wow. What headset does that work with?
