UE4.22 binary huge performance drop for Go / GearVR projects

Anyone else noticing a huge drop in performance when testing their projects in Epics 4.22 binary branch (Oculus SDK runtime 1.32)?

Is there a setting somewhere to fix this?

Draw thread on one project was running at 16-17ms in 4.21 and below, now runs at 27ms in 4.22 !! (results in a good 10+FPS drop)  ::neutral: 

I hope this will be fixed in the Oculus 4.22 branch before it's released?
