IMPORTANT UPDATE : Thanks to a comment below I now have found out that I had not been aware of the separate VR graphics setting in MSFS2020. When you go into Graphics settings it shows PC at the top. Change that to VR and you can then adjust VR SEttings. Having done this I am now blown away by the VR Display in tn the Pimax Cystal headset. Thanks to Andy for letting me know, hadn't been aware of that setting before.

This video takes you through unboxing of Pimax Crystal Light and connecting to a PC. It talks about the software and drivers required to get OpenXR running which is the recommended VR environment to run MSFS2020 using the Crystal Light. It mentions the step required to load the drivers and be able to use MSFS2020 in VR. I am just a beginner in VR and only some experience in using MSFS200. I also cover adding VRRock prescription lenses at the end of the video.
