Good current breakdowns of the VR process chain?

[Voyager]

TLDR; Anyone know a good, current breakdown of how PC VR systems communicate with the game software they could point me to?

 

So, saw the thing about DCS now natively supporting OpenXR, and trying to wrap my head around what that really means. It sort of sounds like it's an API layer that a headset and game application can interface with, with or without the SteamVR application layer, unless the headset or your applications require SteamVR? And because this is an open standard there are open tools that can access functions and tune things more finely than the closed source versions like SteamVR, Oculus or the WMR system? 

 

For an analogy, I'm hearing "dropping in this new Engine Control Module makes the engine produce more power" and I'm looking for "You need the right fuel/air mixture or the bang happens at the wrong time"

Thank you, 

Harry Voyager
