I have used 8xAF (forced in the driver) previously to get rid of the texture-edge lines in the sea, about 2 betas ago, but not since. To simplify its use, AF works on colour edges similarly to how AA smooth’s the edges of objects, which is particularly important in race simulators where you’re looking down a long piece of track with white lines on the edges. It has a somewhat limited benefit in flight sims though, but also doesn’t generally impact performance as much as AA.
