Enabling High-End Mobile Preview Platforms
For some platforms, like the high-end ones for Android OPENGLES 3.1, Android Vulkan, and iOS Metal, you can choose to enable or disable these individually as a Preview Rendering Level that will populate
the preview list for High-End Mobile / Metal. When these target platforms are enabled or disabled, they will be added or removed from the list accordingly.
Use the steps below to learn how to enable or disable these target platforms from being used with the Mobile Previewer.
Start by opening the Project Settings window by going to the file menu > Edit > Window > Project Settings.
In the Project Settings under the Platforms section, select either the Android or iOS section.

For Android OPENGLES 3.1 and VULKAN previews, in the Android section under Build, set the options for Support OpenGLES 3.1 or Support Vulkan.
For iOS Metal, in the iOS section under Rendering, set the option for Support Forward Rendering with Metal (A7 and up devices).
Once any of these have been enabled or disabled you will see the list of supported platforms update in the Preview Rendering Levels list.
