I was wondering about this as well. There could be ways of taking advantage of
it in a custom plugin. eg. write a plugin to perform it's thing in Metal or
other technology (Scenekit?), and output the result back into the QC context,
but I wonder if it's really worth the hassle. If you were really determined to
do some powerful stuff for another QC compatible application it might be worth
it. I've only ever briefly looked at writing a QC Plugin, so not sure if there
would be restrictions that would make it impractical. I was thinking of
basically a QC Plugin that just wraps a self contained visual or effect, while
still allowing access to QC inputs/outputs from whatever application you're
playing QC from.

Does anyone know if it will possible for us to take advantage of speedups from
Metal in QC? Even if Apple does not specifically address that? I mean could
we write individual new coreimage nodes and filters using the QC API and Metal
in order to speed up certain portions of the QC rendering chain?
Or will Metal improvements happen automatically with new drivers from Nvidia
and AMD and we won’t need to recode?
thanks

I have a feeling Metal will completely break QC, unless it's rewritten from the
ground up. Maybe I'm wrong though. Anyone at Apple care to comment?

good question! was assuming it wouldn't touch QC as my guess is it is an
alternative to OpenGL and bypasses it — so won't touch QC either way.
