Question EditorXR is chunky, stuttering in an empty scene

I am using:
2019.4.19f1
EditorXR 0.4.12
The old (recommended) input system
The old (recommended) XR system
with
- VivePro
- RXT2080ti
- i9 9900k

I open a scene with a simple object and start EditorXR
Everything works fine and smooth with me just looking around, but the moment I touch a wand - Everything is juttery, chunky, laggy.
CPU is at 3%, GPU at 10% so it does not seem to be horsepower.

The more I use it - the worse it gets and will never recover (e.g. it's not a matter of letting go of the wands and all is good... once those wands come to life - it is a laggy mess).
If I select an object in a scene... forget it. It is so slow.
Again CPU and GPU are not even blinking.
When I "Play" the scene - no problem... crazy fast.

Also as I use it - more and more help tab callouts shed and populate over the scene. ("press to undo" and "trigger for...")
They get detached from the controllers over time and float in space in various sizes.
If I close EditorXR and reopen - It's nice and fast again.... until I touch a controller.

I have tried multiple installs of Unity 2019.4
I have tired new projects and re-adding the package.

Always the same.
Any suggestions?
