Conclusion.
If you are running Windows 10 19.09 Pro or Upgraded Windows 10 19.09 Pro to Windows 10 Pro 2004 and you see high CPU Useage with Adrenalin 2020 20.7.2 driver or above (to 20.8.3), the only fix I have found is to run a Windows 7 backup to an external USB Drive of your entire system, wipe the original OS Drive. Install a clean version of Windows 10 Pro 2004 and then install Adrenalin 2020 20.8.3 driver.
More info:
Adrenalin 2020 GUI/UI does not like something about Windows 10 Pro 19.09 or Windows 10 Pro 19.09 upgraded to 2004.
or
Adrenalin 2020 GUI/UI is conflicting with some software I had already installed, yet to be determined.
Windows Checks on the drive and the Windows 10 Pro 19.09 and Windows 10 Pro 19.09 upgraded to 2004 passed.
Nvidia drivers worked fine.
Adrenalin 2019 19.12.1 GUI/UI + 20.8.3. drivers worked fine.
The Adrenalin 2020 GUI/UI seems have lower CPU Utilization on new SSD and new clean Windows 10 Pro 2004 install (up to 5% so far).
I will keep an eye on CPU Utilization as I reinstall all of the programs I was running on the original drive onto the new Samsung SSD.
