It's still React, and it's still too slow. The only difference is where the render is committed to (DOM vs Native UI)

Having a declarative rendering logic, a rendering runtime, the VDOM, diffing, re-rendering, update scheduling and everything else that React uses under the hood is always going to be slower than tailor-made imperative rendering.

And let's not even go down the rabbit hole which is concurrent mode and suspense, where React is going to be basically a black box more suited to quantum computing with the whole "render x times and settle on a result that it thinks is correct".

I'm not sure if it will take up more resources than the Xbox dashboard or office plugins, but I am willing to say "yes". The dashboard is quite simple compared to a full-fledged IDE which VScode is becoming, and I'm yet to see the whole Office suite, including the underlying logic, being ported to React Native.

Atom was ported to React at one point but they quickly abandoned it because of the bad performance. Microsoft followed suit and hasn't even bothered with React for VScode.

Ah, that is why Teams dropped Electron for React Native!

Microsoft Teams? No they didn't drop Electron for RN/RNW. They dropped Electron for Microsoft Edge WebView2. I might be missing some sarcasm though
