I'm not clear on what the current state of the Oculus SDK is. I have read they switched over to OpenXR and discontinued the native SDK, but then I see documentation on a PC SDK here:
My immediate goals:
I've used Valve's OpenVR before with good results. I believe it supports the Rift, but I am not sure about the Quest. After working with it for a week, I have a very bad impression of OpenXR.
In order to meet the immediate goals stated above, where should my focus be?
