High-end computer yet very sluggish performance in VR

I’ve tried MSFS in VR with Quest 2, RiftS, Reverb G2.

I didn’t bother much with the Quest 2 because of comfort and the added resources being used to compress video over the link cable.

The RiftS is the smoothest experience because the default resolution is way lower than the G2.
To get a similar performance with the G2, I’d have to lower the resolution to be equivalent to RiftS (there’s no free lunch here!)
Also, on top of that, the Oculus frame interpolation software is just way better than WMR, so head movement is always butter smooth.

Then the one thing everyone seems to be ignoring is that the game streams the world data, and this can have a big impact on framerate.
To take this out of the picture, one would have to enable manual caching and fly over an area that’s been cached locally (that’s just not how I play as I’m doing a world tour).
