First I installed that nhancer and then de-activated Antialiasing in FS.
I opened nhancer and deleted all those profiles.
Then I made a new profile, I just called it FS9 and assigned the FS9.exe to it (think that last step isn't needed).
Then I just most of the settings called at:
http://www.simviation.com/cgi-bin/yabb2/YaBB.pl?num=1183998514Currently I'm using an AA of Supersampling 2x2, an AF of 8x and screen syncronization checked for application.
In the next tab (settings are on three tabs) I have Texture Filtering checked the highest.
All other options and the whole 3rd tab keep unchecked.
I haven't tried out these settings on a "much-addon-scenery-place" yet, but if it works fine I'll try to set either or both AA to 4x4 Supersampling and AF to 16x.
And, yes, there's still another thing to say: I have set nhancer starts automaticly with windows, but there always occurs an error and it exits, so I have to start nhancer manually before flying. Does anybody know a fix to it?
And thank you for all the great tips!!!
