Jack I haven't tried but found a useful set up on the forum which was as follows its well worth a go as dropped my cpu usage to 20% on Windows

My suggestion is to set the Quality slider to 20% and Latency to 2048 (that helps A LOT compared to 4096, probably due to cache sizes). Then tweak your preset and try to make the CPU load as low as possible. Finally, increase it again.
Under CPU & Latency, make sure that you're using 3 (or 4, that doesn't really seem to matter) processing cores with no subthreads per channel, and enable "Ignore high frequencies" (that lowers the CPU load by about 20-30% for FM at 192 kHz).
Things to change to lower CPU load:
- Strictness under the clipper or composite clipper settings. Setting it lower helps a lot.
- Don't use Natural Dynamics or Delossifier. They are really heavy on ARM
- In the Declipper, set "Step size reduction" to 0.75. This has a small effect on audio quality but reduces the CPU usage of it by half.
