taubkin, the thing to remember with the G2 and VR in general, is that it is still very much a work-in-progress technology, that most times feels more art the science. Eye of Newt, as @fearlessfrog likes to say. It took me a while and a system upgrade to where I was using VR most of the time while simming. IMHO, VR in DCS is pretty stable at the moment, while MSFS is still a moving target.
The small sweet spot adds to the frustration, because every time you move just slight off lens center, things begin to get cloudy and you begin tweaking the fit and adjusting IPD.
But hang in there. You will develop practices and settings that all come together to give you an amazing experience. After a while, VR will become more spontaneous and less of a mystery. You’ve already got the right system to get there.
To paraphrase a great movie, if you look around and find yourself in simulation Elysium Fields, that is because 2D is already dead for you 
Edit: In DCS, for me, these two add-ons improve the experience. The first is a visual enhancement, the second for performance.
