RocketChief I am trying this as well and have the same experience. Very smooth until I open a 3D view of any kind, and then the viewport resolution for that view is wrong and the render area flickers with every mouse movement.
It seems to be an issue with the UI though because I'm able to export a ray-traced render without issue, even though I can't see what is rendering in the UI.
I'd love to know if you ever made any progress on this!
