Poor audio performance Cubase 11 audio spikes

I’m running cubase 11 on a Mac mini i7 16GB RAM 512 SSD and since upgrading to a 4k monitor my audio performance as been bad. Im getting a lot of audio spikes. I saw a video on YouTube where the “Steinberg power scheme” was activated but cubase 11 doesn’t seem to have this option. On larger projects my audio performance hovers around 75% and the track isn’t even playing. Anyone got any thoughts on dealing with these audio spikes in Cubase 11 and improving audio performance. I’ve already increased the buffer size as much as I can and it hasn’t helped

Cubase 11 does have the steinberg power scheme option, it’s under - Studio setup - Audio system.

It is only for Windows :roll_eyes:

Oh yes, Sorry, forgot that.
