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](https://qa.fmod.com/t/fmod-studio-2-00-07-being-very-laggy-on-imac-2017-27-4k/15572)

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