“CPU: Update” Indicates the percentage of 20 ms of CPU time the FMOD engine update takes to complete. Unfortunately, without more information, we are unable to diagnose why the value in your screenshot is so high…

Are you able to send us a copy of your FMOD Studio project, as well as the profiler session in which this issue occurred?
