I see. I am guessing it’s necessary for VR? (vsync that is)
Still doesn’t explain 58 fps in empty scene, and 58 fps in maxed out scene. I mean, I wouldn’t complain if there was no requirement to run at 60 fps. It feels perfectly fine to me at 58 fps 
How did you manage to output game/frame/draw/GPU timers under fps counter? I’ve been trying to find cmd for that :o
P.S. Btw, I am on S6 with Android 5.1.1
