I am getting very poor performance out of the "OverlayUIDemo" scene in the Oculus Sample Framework for Unity.
In my testing, a basic usage of the OVROverlay is fine, but when you use a camera render texture such as in the example, the framerate drops significantly.
Galaxy S6 Tested with 5.6.1f1 and 2017.2.1p3
Is anyone using this OVROverlay thing in production?
Oh, thanks so much for that information - I didn't realise updating every frame was not necessary. This makes sense, I will go back and try with this approach.
