Any way to add motion smoothing to the reverb G2 other than using Steam VR?

Have you looked at the post below:

Motion Smoothing is indeed implemented in WMR via the Open XR Developer tools. Enable use "Preview Runtime). This can be installed via the Microsoft Store. It works reasonably well. There are some propeller artifacts but you can try it and see how it works out for you. I am using it comfortably on a 2080Ti/i9900k/HP Reverb G2.
