I agree. Half gfx in VR is still superior because the reality (of flying) is so much more overwhelming.How it performs in VR? Nobody knows except internal testers at Asobo, Microsoft and HP. But I'm not worried, because even if it has to be subsampled (supersampling dropped below native res) on the VR headset, and in-game settings have to be reduced, the sense of presence will make it not matter.
Considering VTOL VR looks like a game with potato graphics from the 90's - and yet when you play it in VR you feel a sensation very much like actually flying - FS 2020 should be a mind-blower even at low settings.
