The problem is it would be extremely hard to track down this kind of
things because so many variables.
It could be because of MacOS, VoiceOver, Keyboard Maestro, Pro Tools,
AppleScripte Engine, some other processors in your computers, or even
possibly hardware difference, and so on.
For example, Microsoft Teams kicks the fan really high and drains the
battery like crazy in some cases on Mac, and it has been a few years
since literally hundreds of people have been complaining about this all
over the internet. Several possible solutions have been proposed by
different people, but Microsoft wasn't able to fix it despite the
popular demand during Pandemic.
Unfortunately I don't have a bandwidth to tackle this.
100ms delay is not bad when you using it, and it only applies when you
use the monitor. I think it's a good compromise.
Having said that, let me know if you find something.
