I can’t help with the Oculus Quest 2, but we got my son an Oculus Rift S for Christmas. I grabbed it early this morning and set it up on my computer and had it running with MSFS in about 5 minutes. I was highly impressed. Framerate was great, though the render scaling low (80%) so it was a little pixelated (though I left all other settings maxed out, so next time I steal…er…borrow his Rift, I’ll play around with the settings to try to get things cleaned up a little. Even so, all steam gauges were easy to read (I mainly fly the 152 and 172 as I’m a student pilot flying those IRL) and the terrain looked really good flying low and slow.
It definitely adds a huge step of realism to the sim experience.
