How much different is Metal's computer shader pipeline vs. OpenGL 4.3? I am interested in learning how to port some OpenGL compute shaders to metal for a game, but some I have heard from a manager that his dev told them it could not be done because Metal is missing some key features of OpenGL 4.3. Does anyone know what Metal's limitations are vs. OpenGL 4.3 when it comes to compute shaders? Thanks.
