Oh, yes, but thats just because you are using FXAA - which is a simple post calculation of every picture. It works whatever you choose.
However, it also blurres the dots (contacts), which makes them quite hard to notice. The game is old and not very suited for new technology. I suggest 8x Multisampling AA (or 16x if you like). It smoothes the edges very well but leaves the rest of the scene clear and sharp (i.e. the landscape). And it will give you better framerates as FXAA.
For Multisampling AA you will need 'Override any applications setting'.
For anisotropic filtering I suggest 'Application' as IL-2 comes with a build in mode, which works just fine (saved FPS!).
And you can disable the 'Transparency-Antialising'. It doesn't do anything valuable for this game and just sucks down your framerate. The same for 'Antialiasing-Gamma-Correction'.
Here is my setting (just in german):
BTW... you should change your signature then.
