ATI and file conf IL2

[SLEVIN]

Hello, can someone help? I have a ATI 5870x2, with latest drivers 10.08.
OpenGL video settings by selecting the menu during the game I have a problem of AA on the ground. I see the islands and the coast have a defect zigzag and very ugly looking.
Can someone pass me a conf file already configured?
How can I fix this?
If I select DirectX can not apply AA to the texture of the aircraft.

Thanks
