Metal frame time is higher than OpenGLES3 on iOS devices
To reproduce:
1. Open GraphicsPerf project;
2. Change platform to iOS;
3. Change Graphics API to Metal;
4. Build and run DynamicVBO and Objects scenes on iOS devices;
5. Change Graphics API to OpenGLES3 and build on iOS devices;
6. Compare the frame time between both Graphics APIs.
Important: please let devices to cool down between tests.
Expected result: Frame time with metal is lower than OpenGLES3.
Actual result: Frame time with Metal is 1-15% higher than OpenGLES3.
Devices under testing:
-iPad Mini 4 (SoC: A8, iOS: 11.4),
-iPhone SE (SoC: A9, iOS: 10.0.1),
