Hi Michael!

Well...on MacOs/iOS/iPadOS machines, Metal APIs are much much better than the old OpenGL simply because they're heavily optimised for the MacOS/iPadOS system.

There are already dozens of apps, both for 2D and 3D, on MacOS/iPadOS that now really fly, thanks to the porting to Metal API.

See you.
