Edit: I’ve changed my mind about reprojection: My 2070 SUPER VR settings and suggestion (Reverb G2 - WMR)
Alright, I’ve been at this for days now, and I’m very happy with things and thought I’d do a data dump which may be useful for people with similar specs.

Optional rambling (mostly about reprojection)
Since this thread is heavy on theory, I wanted to make the first part my tl;dr and then let people dive into my ramblings if they want to.
My lightbulb moment centered around motion reprojection. Once I got this nailed down, I went from “I guess this’ll work for lessons” to “I just want to fly all weekend”. In a way, reprojection makes tweaking FS2020 for VR a very simple, binary experience. Basically, with reprojection enabled, VR either works or it doesn’t. You can kind of stop paying attention to what your framerate is.
Reprojection has a fairly significant cost (though totally worth it in my opinion), and if you don’t know this and/or don’t know how to verify if it’s working properly or not, you’re gonna have a bad time.
There’s a setting in the OpenXR Developer Tools, Display frame timing overlay. If you tick this checkbox, you should see a box in the middle of your left eye next time you’re in FS2020 VR. The box will either blue or red. If it’s blue, reprojection is working. If it’s red, it’s not working, at least not optimally. You’ll notice it shows the reprojection frame time, and for me it was like 3.5ms.
With a headset running at 90 Hz and reprojection capable of inserting 2 frames, 30 FPS is the magic number, which will be obvious to anyone who’s spent any time sifting through this thread. The 3.5ms is over 10% of your frametime budget, so you have to stop paying attention to FPS numbers and start focusing on whether or not your reprojection is working by looking at the color of the frame timing overlay.
In-game graphics settings can have a significant impact on performance, but in my experience, not nearly as much as the in-game render resolution and the OpenXR render scale. You can crank all your settings down and have a blue box almost all the time (whipping your head to the left or right will give you a red blip no matter what). Or you can crank your settings all the way up and have an almost permanently red box. There’s a gray area in between where you have lots of room to tweak, and there’s room for personal preference.
It’s good to realize that sitting on the ground in FS2020 is the 2nd most performance intensive situation you can be in FS2020. The 1st most intensive is the 15 seconds after you rotate off the runway. I used JFK for all my test runs since that’s known to be a taxing area. If you insist on a permanently blue box, then you may be leaving a lot of eye-candy on the table. I’d recommend shooting for a mostly blue box, with no red while you’re just looking straight forward or swiveling your head at non-whiplash rates. If you have some occasional red blips, don’t worry about it. I personally aimed for solid blue for most of my ground time, and 99% of my time above 500ft. I don’t know why, but once you’re up in the air, FS2020 is a lot more chill.
@CptLucky8, thanks so much for all your work. I used all your posts as the basis for most of my tweaking. I feel like the least we can do is start a GoFundMe for CptLucky’s 3080. I am amazed you’ve sqeezed as much as you have out of that 2070S. The G2 just has so many pixels to drive😅
