@sthackrey, I wasn’t very clear, but in amongst all those words, I said that it DOES work for me to change the entry in the registry for OpenXR from Steam to Oculus. I just kept trying to find the reason for it anyway, because I thought there might be others who couldn’t do that and I’ve also heard from one G2 user who describes something similar.
So, for you, it was changing to use Oculus instead of Steam in the registry entry that fixed it? And you know the effect I mean? Very nauseating, isn’t it? I know that some users prefer using the Steam runtime, so there must be something about certain setups (I’m using the Rift S) that causes the problem.
I would like to move up to the G2, but for some silly reason, nobody has filled my pre-order(s) yet! 
I know there are lots of tweaks and details with every headset but, in general, you just use OpenXR and WMR and things basically work?
