I'm glad you found it useful!
I have watched a few videos on getting the quest 2 to work and that seems the easiest. However I can find the Reverb 2 second hand sometimes even new online for about the same price as a quest 2 used. Is the reverb the better unit even if its more of a pain to get working?
As a VR headset for flight simulation on a PC, the HP Reverb G2 is fundamentally better than the Meta Quest 2. But: Both are now a couple of years old; and Condor's use of the Oculus APIs requires the use of Revive, and an older version at that!, to work with the HP Reverb G2.
So both of these headsets are really becoming choices that are more backward- than forward-looking.
Interestingly enough, as you mention that you already have an HTC Vive, have you tried simply using that? You should be able to follow the same instructions as for the HP Reverb G2, simply skipping the "Windows Mixed Reality" (WMR) related parts.
A lot of new stuff was announced or demonstrated at CES just n the past week or so; it may well be worth sticking with something "cheap&cheerful" for a VR headset
right now, when there are much better headsets coming within the year ahead.
This article on mixed-news.com seems to be a fairly reasonable roundup of what is (probably) coming in 2023. The Vive XR Elite does look quite interesting, Heck, even the Pimax Crystal is beginning to look like a credible option (and with a nicely wide field of view for flight simulation in particular) – and that's without even considering the very-strongly-expected Quest 3. And if the rumoured "Valve Deckard" turns out to be real ... that could be quite something.
This is why I am, for now, sticking with my original Oculus Quest – because what is available
right now doesn't seem to me to be a big enough step forward compared to what I already have.
So you might consider a second-hand Quest 2 as a stopgap device!
The HTC Vive I have requires the lighthouse modules and I am thinking just going with newer tech might be better. Also since this will be used in an environment with kids whichever is more stable may be best and curious what you think on that.
Lighthouse tracking is fundamentally more precise, but I've always found my Oculus Quest (v1) to be perfectly fine. While there have been complaints about the inside-out tracking on the HP Reverb G2, those tend to mainly be about tracking the controllers in high-speed movements or similar - which does not apply to Condor.
The big advantage of inside-out tracking is that you don't need to set up any base stations; you don't need a more specific 'VR environment setup' than simply, put on your headset and choose your play area - which, for something like Condor, can usually be a 'stationary guardian' (in Quest parlance) or similar. It also means there's no risk of any disturbance to any base stations, because there aren't any!
My biggest worry with VR is when I played with it before, all the game's I played were fairly short so fatigue was not much of an issue. In condor some of the tasks are quite long and curious if you find VR a bit taxing? One thing I can do is have a monitor mounted in front of me and should I get a headache I can always pull it off and use the monitor. Or for short flights and training use VR but for long racing tasks use a monitor. Have you had any issues with long tasks in VR? Sweaty or fogged headsets?
I personally have never had any issues flying Condor in VR even for multiple hours at a time (... with the headset connection wired for highest image quality, and so that the headset is charging while in use so I don't run out of battery) - and that's with the original Oculus Quest (v1). But I fully realize that this can differ greatly from person to person; the only way to find out is, really, to try.
I use to work for a VR company and designed hardware but in the end the company switched to just making games. The company I worked for is Survios and their 2 big games were raw data and creed. At the time they were developing Raw Data a group of us were also developing our own headset and it was so good it got us 65M in VC funding. In the end HTC made a deal with Survios to shelve the hardware we created and in doing so they would bundle Raw Data at launch of their product.
Hardware development is difficult and expensive. It would still have been very interesting to see the Survios headset, and where it might have led!
