Illustrator 2020 (version 24.0.3) for MACOS
Now Illustrator 2020 (version 24.0.3) doesn't use Apple Metal API. they just use OPENGL that means gpu performance are slower. why aren't they use Metal API? it's not faster than open gl api? It's very shame that they aren't using a metal api.
smooth. it's smooth because they are not using a apple ui framework. if they use apple ui framework it will run smooth and faster.
