      Does Metal limit support to specific GPUs? Thought it was all tuned to the iOS device GPUs.

      @tapbot_paul on iOS it makes the assumption GPU and CPU share memory. Not sure about Mac yet. If same -> Intel only.

      @rsebbe @tapbot_paul Modern GPUs can share memory with the host more or less transparently, with the help of the OS and drivers.

      @jfroy @tapbot_paul Ok. will be interesting to see how they are handling this with Metal on Mac.

      @rsebbe @tapbot_paul Real questions: What has been accelerated through Metal (CA, CI are known, Quartz?)? What GPUs are supported?

      @jfroy @tapbot_paul 1. Let’s see (easy from Instruments) 2. hence my question : limited to unified-mem GPUs, or exposing memory transfers.

      @rsebbe @jfroy @tapbot_paul This is my one big, burning question.

      @warrenm @rsebbe @jfroy @tapbot_paul Craig mentioned Core Graphics, but if Quartz 2D Extreme didn't work for them, not sure why Metal would.

      @LucasTizma @rsebbe @jfroy @tapbot_paul More reasons than I can even enumerate here.
