The rendered stream version of VR doesn’t even do it justice, but it is still smooth on live stream with people in chat. Not sure about other YouTube VR videos, but I stream VR all the time and the experience in the headset and on the stream is very smooth (of course streaming software does introduce a bit of a delay). I use a physical yoke (boeing/GA) and stick (airbus/cirrus), pedals and TQ. I currently use a Quest 2 with my PC running an i9-9900k OC to 5.0GHz and a 3080 Ti.

I have no experience with VR on a console - I have only ever used PCVR. Almost all headsets have an adapter that can be used with eyeglasses. You just have to be willing to put in the time and effort to tune your system to get the right balance of visuals and performance based on your hardware. For me, once I tried VR a few years ago, there was no going back. You are right that there is a decision to be made between monitor (multi or single). I have been using VR for years now on the other sim and now on both MSFS and the new version of that other sim.

I fly only VR anymore usually on the VATSIM network.
