High CPU load on one core when using multi-core machines

  • Live Versions: 6 - 9
  • Operating System: All


High CPU load on one core only when using multi-core machines.


Live cannot use multiple CPU cores to process a single track or signal path.

Additional Information

A single track that has multiple plug-ins can only be processed by one CPU core. Sending audio signals from one core to another would cause unwanted delay - the result would be a dropout or another artifact.
This means that a set with only one track can cause a quite high CPU load if the track contains CPU-hungry plug-ins.
