Run ddu.
Shut down pc.
Re/Re gpu.
Let windows install new gpu with default drivers.
Run SFC, then DISM.
( search ms help if your not familiar with these two )
Reboot pc and install new drivers only or Adrenaline package.
Delte rolling cache and select your graphics options.
I’d go ahead and set up Resizable Bar at this time also.
MSFS isn’t programed to take advantage of this yet but maybe one day. This needs a bios setting turned on, also in Adrenaline.
