Too much CPU consumption

Good afternoon friends.

I recently upgraded from Cubase 9.5 to 11. My OS is Mojave 10.14 - 2 GHz Intel Core i7 - 8gb ram. In principle, I shouldn’t have a problem running smoothly with the program, and I’m having serious performance problems because with only 6 tracks and 2 native plugins , Cubase’s CPU consumption increases dramatically.

Somebody could advice me to fix this?

Thanks 😉
