Great article (disclosure: from my colleague at Boiling Steam)! Definitely learned a lot as a newbie to VR on Linux. I'm still new to VR but not Linux gaming, and have been having a blast. I really appreciate it especially in the winter (great and fun workouts while playing games) and when other activities are limited due to the tragedy that is the US coronovirus response. The sense of space is what really gets me, never have I felt so transported somewhere else. This is in contrast to things like 3D movies where stuff pops out at you, while this gives depth and openness as you step into huge rooms, landscapes, whatever.

I also wrote [0] about just getting the Valve Index and playing on Linux with my aging but still capable desktop (poor 970 was still going strong but VR is really pushing it).
