Regression
Yes
[XR][Android] Application that contains Surface Shader has worse performance on 2017.4.1f1 and later versions
How to reproduce:
1. Open attached project and change to Android platform
2. Build and Run project on Android device (Oculus VR SDK is enabled by default)
3. Observe the FPSCounter UI text or check the FPS with "adb logcat -s Unity VrApi"
Result: 2017.4.1f1 and later versions have a slight performance regression if Surface Shader is used in the scene
Regression introduced with - 2017.4.1f1
Reproducible with - 2018.2.0b2, 2018.1.0f2, 2017.4.2f2, 2017.4.1f1
Not reproducible with - 2017.4.0f1
Notes:
1. Did not experience any performance difference when VR SDK's are not used
2. Seems to happen on Daydream and Cardboard VR SDK's as well, same behaviour with Multi-Pass and Single-Pass stereo rendering methods

Resolution Note:
Spoke with Oculus on this issue, and given its legacy nature and our moving support away from the built-in rendering pipeline and other XR settings, we are closing the issue out.
