Ruined it quite a lot for me. I’m still sticking with 475.30, didn’t try the latest driver, but the openxr update is an obvious downgrade in performance for me.
I7-9700k,
32gb ram,
rtx 2070
UPDATE: Excuse me, i just noticed in MS store my Oxr isn’t even updated to latest ver lol 
So scratch my initial statement. At least until i test it updated
