do not enable in-game AA as that overrides the video card and sets the DX flag to the API directly
In your FS9 graphics settings.. I think its the Hardware tab as I recall
Check in: Render to Texture, Transform and Lighting
UNCHECK AA,
Set to Trillinear Filtering
Mip Quality 4 (note set to 4 for now.. you can try higher later)
Hardware Lights 8
Global Texture Slider 100%
This issue may very well be becuase the user is not setting up Nhancer correctly and there are reported issues with FS9 and Nhamcer which deal directly with no AA control
In Nhancer, do NOT set up a new profile.. delete that
In the menu at the top, OPTIONS menu.. make sure to select “ALLOW OVERRIDE OF PREDEFINED PROFILES” is selected
Get rid of any profile you mande manually for FS9 other than the default
Select the FS9 profile and proceed to set up Nhancer as I posted.. making SURE the option: ENHANCE IN GAME AA IS
UNCHECKEDSwitch to global and verify the same settings
that should fix the issue
Prior to the new Nhancer there was another method of getting AA to work with FS9 when the ENHANCE in game AA setting was checked and unavailable to change
