As stupid as it might sound, we are getting incrementally worse performance for our GearVR app on Samsung Galaxy devices. s6 performs the best at ~60fps, s7 at ~57-60 and s8 at ~25-30. We've tried unity versions 5.6.0f3 and 5.5.1f1 with similar results. We have also tried Oculus Utilities v1.13.0 and v1.14.0. Has anyone else faced similar issues?
The profiler shows substantially high amount of time for Camera.Render for s8(~12ms) than s7(~3-4fps).
