text: Title: Didn't use Cpu on m1 Mac
  Body: I've been using the program for a while, and it goes well. However, I found that it barely use CPU on m1, while the GPU is fully loaded, the Cpu is barely used.
  Does it use Cpu on other platform or it only use gpu? I've heard that apple has built-in machine learning units in their m1 chip, maybe we can make use of them in a future update.
