edit: well this became a bit longer than I initially planned, I think I just had a lot to share when it comes to my recent VR adventures.
Well here I am: I initially got queasy as soon as I moved, then I'd immediately stop and take a break, longer breaks in the beginning. Initially I got a strong sense of de-realization / depersonalization after getting out of the digital world (i.e. looking at your hands and your brain being confused if they're real) But that also went away very quickly. The nausea, and 'am I still in the matrix' feeling got better within days, and went away within weeks. Now I can stomach any crazy topsy-turvy locomotion in any game. But I still feel the sweat and excitement, when swinging off 1000 feet high cliffs in Jet Island, or diving hundreds of meters deep in Subnautica.
It's just amazing how immersive it can be. I think you can only get there by having it at home and really giving yourself the time to get into it.
It's also re-ignited my love for single player games, especially modded triple A titles like Dragon Quest XI, or Resident Evil 2 (Remake) for example.
And btw, I run all of this on (arch) linux, on a Valve Index kit, using both SteamVR and OpenXR through Envision (Monado). It's been a bit of tinkering but that's only made it more satisfying for me. Plus, there are great communities like the Linux VR Adventure group: https://lvra.gitlab.io/
