Ok, your new code is really good on WIndows 10 (well, on my Surface Book), but on my Xbox One it's too slow. Sometimes it's ok (but not at full 50FPS). It's really impressive to see my game on my Xbox One X, but a good framerate like on my Surface Book is all i want for now ^^
You can test the app on your Xbox One as it is available on the Store:
