Quick update on where I'm at at the moment ...
General :
Choose a physical button that is never going to move (I use one on my throttle because no matter what I'm doing that never gets moved) and dedicate it for a 'reset VR view' button. You'll need one in every VR game you play, whether you get told you do or not.
Flight Simming :
Amazing IF you like low slow simple VFR. Anything complex, well, stop and ask yourself how do you read a checklist or look at a chart or your notes while you're wearing a VR headset ?
You absolutely need to fly using your usual joystick / yoke / throttle / pedals etc. But no keyboards or streamdecks.
It is necessary to map as much as possible to buttons on your joystick / throttle, and be able to find the right button when you need it without looking.
P3D looks WOW! largely because I have superb scenery and planes for it, I have equally superb planes for XP11 but only default scenery and it shows.
The VR interface in XP11 is what you would expect, I can either select and move switches etc with the lasers, or I can move my "hand" right up to the switch and just move it. I'd be game to try and use a G1000 cockpit in XP11.
The VR interface in P3D works and that's the kindest thing I can say about it, in fact it's the only thing I can say that doesn't include

.
I haven't flown MSFS for a couple of months now, couldn't comment about it.
No Mans Sky :
Gets more and more stunning. Some things are harder to do, some things are much more intuitive. You can get away with flying just using the VR controls. I still can't work out the jetpack properly

You can see a lot more when you're NOT in VR, but that's normal isn't it - when you watch someone walking down the street you can see a lot more of what's around them than they can.
Driving :
You need your usual wheel / gears / pedals / whatever, and you need to have buttons for the secondary controls (wipers, lights, starter etc) mapped so you can get them without looking for a keyboard. Don't even try to use the controllers, I don't think any of the games I play even see them but I once you're sitting in the car it's too amazing to care.
ED :
Ask me after tonight

Update : The G2 controllers are not supported by ED. The hanger looked good in the headset but as far as I can see ED is like a driving game with the G2, in that it looks amazing but you have to have everything mapped to buttons on your joystick, if you need your keyboard to do anything you're screwed. And I seem to recall (it's been a while) that quite a lot has to be done with the keyboard. During the time I spent sitting in the cockpit of my Python I couldn't even select anything, moving my head around turned the various displays on and off but no way could I select anything, the only way I could make anything happen was to use the keyboard to navigate the highlight cursor to what I wanted and press enter, I tried both mouse options available but couldn't even get a mouse cursor to appear in game, when I found the ESC key on the keyboard it brought up the game menus and the mouse worked fine there, but it doesn't work in game. ED is a big fat scrub for me.
Update 2 : It's a godawful interface, it's worse than P3D. The way to navigate the screens is with the hat switch and trigger on a joystick. And the hat switch has to be set up for this, as does the joystick/throttle for the flight controls, and the galaxy map has to be set up differently (haven't sussed that yet). Now that I'm doing it (can't have played ED since I bought this PC, it was installed but had never been run) I am reminded of ED's cute habit of showing controls being assigned by default but not actually working until you assign the exact same controls again manually. Still, nothing that 6 million credits couldn't fix, and the view of the detention centre as I flew away was pretty stunning. And I bought another sidewinder to make practising crashing a bit cheaper. I managed to find my way to a system that had a proper orbital station, and managed to get to it and autodock. OMG. Just .... OMG. It's painful, but it's definitely not a scrub any more.
