[2022] Support for metal renderer on macOS?

Still unsupported, unfortunately. Badly broken with reflections turned on. Thank goodness for OpenGL.

I expect Metal to be buggy, so I stick with OpenGL. Turn off all reflection-related settings for sure. I don't know what settings are more or less performant under Metal. I'd probably start by following the same advice people get for Windows on what to turn down. You can find plenty of existing threads about performance.

My role is to moderate the forum, not develop the game. But I’m with you; I hope the Metal renderer is supported in the future.
