Do you have anything else running on your projects? System overloads could be caused by multiple factors. Check if you’re running other processes while working on your projects. Take a look at our guide for macOS optimization.
Also, check the System performance monitor inside Logic to verify if the system overloads are being caused by CPU, RAM, or Disk usage. If none of the above shows unusual behavior, it could be due to the Plugin itself, but it’s hard to tell without checking the performance monitor first.
