VERY high CPU usage while working in FMOD Studio 2.0 on MacOS Catalina

As soon as I begin playing back even a minor 3D event with only a few audio tracks and minimal processing, my CPU usage spikes to over 100%. Does MacOS just not like FMOD? The computer has an Intel i9 - 9900K. I do only have 8GB of RAM (waiting on more to arrive in the mail). Could that be my problem?

This issue has previously been posted here - FMOD Studio 2.00.07 being very laggy on iMac 2017 27" 4K

On suggestion from that thread is to see if running in low resolution mode improves performance.
