Problems with antialiasing and texture filtering in DX10

[The320Pilot]

When I had an ATI card I used Radion Pro, you can create game profiles like with Nvidia inspector.

Yes, sure. I created a profike for FSX like one year ago and I made some changes to it in order for DX10 to --supposedly-- work correctly. (Spoiler: it doesn't work well.)

Now, I added MutiSamplesPerPixel=8 & MultiSampleQuality=8 in the [GRAPHICS] of my fsx.CFG file, as well as the D3D10=1 and checked at RadeonPro that the AA is set to Use application settings. The AA is very poor compared to DX9.
