Yes I am the same person as sparker on x-plane.org. When I started streaming I added the InVR and is my name on Twitch and YouTube. I have tried X-Plane in VR on Linux but had a double vision issue that the developers did not seem to want to take the time to resolve it then MSFS came along.
I do not but do have a friend that does run MSFS on Linux using Proton and did seem to work fairly well for him.
