Linux gaming is looking pretty healthy now.
An obligatory shoutout goes to Ryan C. Gordon (icculus) for this continued contributions to native Linux gaming too (currently working on porting Descent 3). He made it possible for me to play some of my favourite games on Linux well over a decade ago.
VR is the one thing I’ve really been wanting on Linux. I held off on buying a Vive for my PC (I have PSVR though), due to the lack of advertised first class support for Linux, but it seems that the Index kit is fully supported on Steam OS. I’d buy the Index kit right now, if it weren’t for the long list of RMA horror stories I keep reading about on /r/ValveIndex. If Valve could improve quality control on their hardware, myself—and I’m sure other Linux users—would be more inclined to purchase it.
