The Valve Index ownership has grown on Steam by 20%, according to the latest Steam hardware survey results. The total ownership has gone from 0.5% of users to 0.6. It still may not sound like much when compared to the Oculus headsets, however it’s quickly catching up to the WMR headsets already. The popularity of the Index is expected to keep growing throughout this year too, it will be interesting to see the Steam hardware survey results at the end of the year!
This data should be considered an estimate and may not be fully accurate, the Steam hardware survey is often buggy and refuses to detect VR headsets on some systems (including mine!). I’d expect the real numbers are slightly higher if anything. The fact that your headset needs to be plugged in and turned on while you are doing the hardware survey makes me think that a lot of VR headsets owners will be excluded sadly.
