I'm sorry to hear about Movement's high CPU usage on your machine. Please try using the Low CPU Mode? To do so, simply click on the icon in the bottom left corner of Movement's GUI (pictured below):
This will freeze all motion graphics but will not affect the audio. If you're on a PC, please make sure that your graphics card driver is up-to-date.
Also, please make sure you're running your DAW in 64-bit mode and try using a Buffer Size of at least 512, higher if possible.
