what is the best new Mac hardware that you’ve tested to speed up the rhino 7 cycles ?
Video cards, cores and so on?
Sadly, that’s not possible currently.
Apple has not made that reliable in their drivers.
There is another Forum thread about this but I can’t find it.
That GPU speed up in a Windows only thing for the foreseeable.
Hopefully someday when Cycles has a good Metal-based backend…
