M1 CPU usage seems extra-ordinarily high? #36

After compiling a Release build for Apple Silicon, I'm observing that the standalone RAVE plugin is using 500-600% CPU (e.g. 6 full cores) and playback seems to be MUCH less than real-time (e.g. significantly dropping buffers) using both the Vintage and VCTK models. I'm using a high-spec 2021 M1 laptop, so it's likely that this is the best performance available on Mac apart from a few much newer / non-laptop Apple machines.

What's the expected performance for the rave vst? I would expect it would work for SOME realtime playback cases on a high-spec machine, since this is clearly how the plugin is designed - am I encountering a mac-specific bug here, or a bad build configuration of some kind?
