The ONLY thing keeping me off Linux atm is VR.
My use case is more specific than just a Valve Index though. I have a Windows Mixed Reality headset (Samsung Odyssey HMD+) and requires windows to run well and feature full.
I really like having the option to whip out VR at a moments notice. Maybe ill dual boot linix, but it seems like a pain for whats essentially going to be my home media console/gaming rig.
I did turn my old rig into a Linux computer for my personal desktop. Loving Pop OS! From a casual perspective. I just need my browser, steam, and some FOSS linux alternatives.
