Yes, I’ve just talked with Oculus devs directly. It’s working on ES2 but renders one left eye with Mobile HDR turned on. Also reflections is gone.
Without Mobile HDR it’s full stereo but reflections is still gone. Also didn’t support spherical image cubemaps/HDRI for background (I think it’s ES2 feature level problem, not Multi-View).
I can’t judge overall performance improvements for now.
