I can't get AA in windowed mode. Never could. I'm using latest drivers. RadeonPro crashes FSX... so I can't use that.

I don't use AA at all with my 7850 ATI card, but rather SweetFX with the SMAA injector.

 

It's not perfect, instruments may lack a little clarity, but it's easy on the frame rates, and SweetFX is configurable.

 

Another drawback, SweetFX doesn't like third party text overlays, such as frame rate counters, which cause it to crash.

Thanks. I solved it in CCC. I use SweetFX without SMAA . I'll try that out.

How did you solve it?
