How to get programmatically the maximum texture size (width and height)

Question

How to get programmatically the maximum texture size (width and height) with metal? with openGL i can do: glGetIntegerv(GL_MAX_TEXTURE_SIZE, ...) but how to do it with Metal ?

Answer 1

There is currently no API for retrieving the maximum texture dimensions of a Metal device. You should consult the Metal Feature Set Tables for this information and include it in your app instead.

For A9 and newer GPUs running current versions of iOS/tvOS/iPadOS, the maximum size of a 2D texture is 16384×16384.
