A bit of feedback from another new user of the Rift S:
After dithering for several months, I finally ordered a Rift S last week and had it on Friday in time for the weekend.
I'm used to playing on a 65 inch 4K TV which looks fantastic.
I'd endorse most of what I've read on this forum, in that the sense of immersion is great, but after a 4K screen the resolution is very poor. However, the poor resolution is only problematic part of the time. The chief issue is with things in the middle distance. So a tanker in the distance is just a fuzzy blob, and the same is true for the carrier.
However, once you get close this ceases to be an issue and the sense of immersion takes over. You see the whole of an enormous C130 floating above you, and refuelling becomes even more fun than it already was. Being able to see the precise relationship between the basket and your refuelling probe is great - no comparison with the 2D version.
The carrier is a blob until you get close, but those last few seconds as you land there's a real sense of the size of ship.
Reading cockpit instruments is not a problem for me, and of course there's the zoom function if you ever do have an issue reading a particular figure. I understand that the Rift S is a big improvement in this respect. Speaking of cockpits, the sense of being inside a cockpit is extraordinary - no amount of TrackIr is a substitute for this. The inside of the canopy actually exists as a real 3D object, and the HUD is also transformed.
Lighting effects - sun's glare - and volumetric clouds also work very well.
I had been a bit apprehensive about narrow Field of View, but haven't been aware of this as a limiting factor. IRL a helmet would limit a pilot's FOV to some extent in any case.
Sense of height and speed is enhanced and I occasionally found myself with a moment's vertigo. However, I see this as an endorsement of the realism, not a problem, and I didn't feel unwell at any time over many sessions over the weekend. Mountains, hills and valleys all become far more 3-dimensional - flying low and fast over a ridge feels real - there's a genuine sense of an actual hill top.
I'm a ground pounder rather than an A2A fan, but I did fire up a WW2 dogfight and the first time you have an enemy zip past you in the initial merge is a revelation. The only problem with dogfighting is going to be resolution and identifying aircraft.
My hardware is decent - 32 GB RAM, 1080 card - but not extreme, and I can say that I haven't yet been conscious of any performance issues.
I've found the headset as comfortable as one could expect, and no problems as a glasses wearer once you work out a routine for putting the headset on and off. I just loosen the retaining knob at the back and rotate forward from the back so that headset falls clear of my face.
Could I go back to my pin-sharp huge TV with TrackIr? Probably not, but I'll certainly be looking at upgrading to a higher resolution VR headset before too long, I suspect.
