Changing CPU Power settings is done through windows power management.
Go to the search bar at the bottom left and type in Power Options. You will get something like edit power plan in the fly up menu, select this, you want to edit the advanced settings. There are various ways to get to this option but this seems the easiest. You want to change these bits.
Power Options/Advanced power management.
Processor Power Management - Minimum State(change to 100%)
Processor Power Management - Maximum State(change to 100%)
I am running an i7 laptop with 8gb ram and a Line6 Kb37. And it all sounds awesome now, with power settings changed I can now max all my latency settings with no clipping or crashing. Everything is synced super tight. Previously some midi notes went missing when playing them from a drum kit. That is fixed too.
AD2 runs like dream. Love the Fairfax Vol.1 medium room.
This fix seems to be the wholly grail for my basic home setup running sonor professional.
Thanks to Doktor Avalanche for worldly guidance. His post put me on the right track.
