Summary:
Using OpenGL in iOS simulator with Xcode 9 is so slow it is impossible to use. I am unable to create update for iPhone X of my navigation app because it uses OpenGL all the time.

Steps to Reproduce:
Launch app using OpenGL in iOS simulator and observe the performance. Apple Maps is also affected.

OpenGL has reasonable performance, e.g. at least 10 fps for Apple Maps type of application.

Actual Results:
Application similar to Apple maps performance is about 0.1fps
