...heck

I get some jaggies on the wings of this aircraft. I tried everything to get rid of it but i just can't. AA is 4x Anisotropic is at 4x. Mip map for the card is on for quality and vertical sync is set at always on. Direct 3D is set at for quality. the FS global size is set to massive and is at trilinear filtering. in game mip is set at 4.
I get these jaggies ever so often.

If there is anyway to fix or reduce these that would be great. Also do you think that my settings affect my FPS that leads to affecting the quality?
Thanks
Here is the example. NOTE the wings.
