Did you look at a lot of 2015 Oculus pre-release dev kit hardware videos with hackjobs to support this or that not-made-for-VR game during your time taken to "look into" VR? Like that one you embedded in your post? I do hope not, it doesn't really represent the state of VR as it stands, even for non-VR games.
VorpX allows you to play loads of non-VR games in VR with just headtracking if that's your thing so you basically already have your ideal form of VR right there. As for picture quality you can get higher res/fov sets like Index, Pimax, XTAL and naturally every new year brings higher resolution models to market.
However, thankfully most VR developers are going all in with hand tracking and offer unparalleled immersing experiences with next level gameplay, not relegate VR to being Track IR v2. If there ever is an actual ARMA VR it would be so disappointing to not see it incorporate elements of Onward & VTOL VR
After all, cockpit games like DCS and DiRT Rally and Elite Dangerous and recent IL-2 Sturmovik games and their expansions support VR but do it in that same barebones vorpX style manner which, fitting as it is for cockpits, is barely talked about compared to all in with tracking games like Saints & Sinners.
