Hello Mark,

Dx10 ignores any AA settings in Nvidia Inspector which is why I have it set to Application Controlled.
Ticking the Antialias box in FSX display settings activates it and the level of anti aliasing is controlled by the two lines added to fsx.cfg by the Fixer.
The first line determines the AA level and the second should match the SGSS setting in NI.

Regards,
Nick
