Yes I am. I am achieving about 18fps while using the Reverb G2.
I recently watched a YouTube video of someone using an app called OpenXR Developer Tools for WMR. It’s similar to Oculus Tray Tool in that it smooths gameplay. In that there is a Custom Render Scale setting. With that at 70% I can achieve frame rates that look like 60fps with little jitters here and there, but it isn’t bad, though the resolution is downscaled and not to the potential of the G2. I can play smoothly, but details are not as sharp.
With Render Scale check box ticked off (Original Resolution) and Motion Reprojection turned off in the app (Is this where you found the Motion Reprojection setting?), I can achieve about 26fps. It’s full resolution, but nothing still in the range you are talking about.
These are my VR settings:
