So Ive had VR running a couple hours now and done some reading and used a few settings from other posts as a baseline. To start with, all I had to do to get my Rift S working with MSFS2020 was disable HDR in windows to my 4k TV, and turn off the ‘Use FOV Stencil’ and ASW OFF in Oculus Debug Tool. I havent tried any places like New York yet or the like, so take this with a pinch of salt, until i try those tomorrow, or you try them locations yourself. But these are my current settings and my hardware.

On n a flight from San Diego to San Fran I was seeing 37-40FPS on the runway at San Diego and during the 1st half of the flight. I stopped as I had something else to do but the 40fps was smooth and i suffered no stuttering or drops lower than the 37fps using oculus debug tool Performance HUD.
I turn it off as a legacy from my sim racing. I used to turn it off for that as when it kicked in on rare occasions (before I had my current hardware) it would cause more problems than it solved. On my system it has a habit of turning back to auto after the pc being asleep so I just leave debug tool open but minimized.
40fps, which I was getting once I was around 1500ft above ground, is half the Rift S refresh rate so ASW wont be kicking in at that point anyway. It may be a benefit being turned on say when at an airport or on approach and the fps starts to dip…another thing I need to test.
As I said I have loads more tweeking and experimenting to do.
I’ve found that rolling back the Nvidia drivers to the ones released with this sim (August time) have helped quite a bit for a smoother VR experience.
Rift S here as well with ASW set to off running off a 2080 Super, 32gigs of Ram and a 8700k @ 4.8ghz.
