I have Mac Studio M2 Ultra. The batch convertor which I had to pay extra for is extremely CPU inefficient. We need parallel processing in order to provide a faster workflow. Judging by how good Studio One itself is with mixing large sessions, I am thinking it's definitely a bug. BTW the 8 on the right (on the cpu meter) I believe are efficiency cores. That definitely needs to be changed to using performance cores for such a resource intensive task. Thank you for your time.
I could not upload a photo for some reason but hopefully this link works:
