If I turn AA up x8 it still says x4 in the config.ini file.
Even so i run both il2 1946 and IL2COD at 1600x900 aax4 and in 46 if I hit flyby the plane can fly all the way into the distance and it never looks blocky even when it is the smallest level of detail. So it seems the AA in COD does work but not very well... maybe it's the shaders problem mentioned by earlier post.

with new beta fullscreenmode switched to "on" AA still isn´t working above 2x....:(

Clearly AA isnt working here, do you even know what it is? If it is working at all its not more than 2x which might as well be nothing. 4x is the only way to go as far as performance and quality go. I have tried all settings and cant get it to work past 2x. A complete joke...

Completely agree, just look at the edge under the tip of the Right Wing.....looks like a Hack-Saw! So does the back-edge of the Rudder!

That is not AA, and I'm not even sure if AF works.....?

Currently my Copy of CloD is parked ina Hanger waiting for September 15th....maybe they can fix it by Battle of Britain day?

Who knows?
