Antithetical

As I mentioned in another comment it plays quite well. At least with the Steam Index that I use. Most games seem to work out of the box. One thing that isn’t currently implemented is BT communication with the lighthouses which is a bit annoying but there are other apps and tools to workaround that.

I also run on Linux exclusively and I could play Half-Life Alex almost flawlessy on the Steam Index. And other VR games as well, including Beatsaber, Gorn, Walkabout Golf and many others. I’m really grateful to Valve and their Proton.
