Hi,

Marco, good points! I'm a Mac user, and OpenGL and OpenCL support for MacOS has been relatively crappy for years now.

Michael, I'm pleased to read that BGFX also supports Metal. I have to say that my non-developer impression of Metal is quite positive, especially the new version 2. My experience with Metal comes from the free AMD Radeon ProRender renderer which is compatible with multiple 3D editors, including Blender, Maya and Cinema 4D. Since they recently decided to switch to Metal 2 for MacOS, it renders blazingly fast on my AMD GPU.
