Valve lists the percentage of “Steam users with VR Headsets” in December 2024 as 2.13%. Without adjustment, that’s not remarkable. But when adjusting the figures for each month since Valve started reporting this figure to be relative to the number of non-Chinese users, as China essentially has its own tangential VR market, it’s the second highest ever. Even without this adjustment, the data reveals that more Steam gamers use a VR headset than use macOS or own an RTX 4090 GPU. Further, almost as many use a VR headset than use Linux, which includes Steam Deck, and around half as many use one than own a 4K primary monitor. So PC VR remains a relative niche, yes, but no more so than a Steam Deck or the highest-end NVIDIA graphics card.
If you use Fedora or Arch, Envision can be installed through the Terra package repo and AUR respectively. With envision, you basically just select lighthouse, hit the build button, hit the calibrate button with your headset on the floor, and you’re ready. I personally don’t like all the different windows that SteamVR opens with many having visual glitches on linux. Since I’m using a Pimax headset, SteamVR does not work for me, so Monado is my only option.
