Quest 2 performance - SteamVR vs OculusVR OpenXR... Why does SteamVR perform better?

Ryzen 3800x
RTX 2070s
Quest 2 (72Hz 1.2)

With Link and OpenXR I was mostly stutter free as long as I didn’t fly any planes with glass instrument panels (screens). Flying any of the larger planes made the world very jittery and unplayable.

I recently tried VD and SteamVR, but I was getting constant stutter no matter which plane I few. I was using the VD Medium settings that I use for most other games. I switched back to Link, but kept using the Steam VR XR and although my general performance was lower, the flying was smooth for ALL planes (even better than when I was using Oculus OpenXR). And since the release of Steam VR Beta 1.16.2, it has only gotten better. I can now up my in-game settings with OTT set to 30Hz and it is quite smooth. There is the occasional warped image if I move my head fast, but it’ll do for now. I actually spent the last two days flying and trying out all the other aircraft that I couldn’t fly before due to performance issues instead of constantly tweaking settings. It was refreshing.
