Nice. I’ve been through this myself on my setup with the G2 and it is hard work 
One thing you might try, looking at your config, is to try turning custom render scale in OpenXR to off, i.e. not have a fixed number. Recent versions of OpenXR seem to be doing a really good job of doing this automatically.
In my case made a great improvement while out bush flying but also makes more built up areas more bearable. Of course, YMMV
