MPS is running slower than CPU on Mac M1 Pro

Hello everyone.

I have been recently testing the new version 0.3.0 on my M1 Pro but I found that following the steps from How to use Stable Diffusion in Apple Silicon (M1/M2) the execution times for CPU and MPS are on average for similar prompts:

  • GPU: 331 s
  • CPU: 222 s

Has anyone tested it too ?
