In short, looks like OSX 10.11 doesn’t use Metal to render anything.
Update: Metal seems to be used for gui on Intel graphics.
The new OSX 10.11 beta 2 (23/06/2015) definitely seems snapper when drawing any of the UI.
When monitoring the GPU it’s much more active than it was in beta 1.
Still no sign of the 2nd GPU being used though.
Still fresh build. I believe they try to sort out problems with low framerate on retina laptops under Yosemite thats why Intel got support firstly.
We have to wait lil bit longer to talk about.
