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)

Makes 4.22 unusable for mobilevr unfortunately :frowning:

Haven’t tested this, but if this is really an engine issue i guess people will have a hard time developing for oculus quest

It seems 4.22 release is rather buggy for VR. I found out that custom depth buffers are misaligned when using instanced stereo / multiview…
