Best FPS for me has been by using in game workshop AA setting and leave card settings to application control.

Thanks yeah can best sometimes Wodin. Or override works well for some people.
The main problem is using "enhance" or whatever as that adds too on top of the in game one.

Vertually every article I have ever read on maximizing FPS in a game says to use the in game AA first because that is what the original Dev's optimized the game with.

Yeah for sure Panama, just since cfs3 was made then we have new DX shaders and a zillion GPUs so for some the other option works
