In layman's terms, does that mean that SAO has actually become usable to us who call it "Smooth All Objects"? B-frames in x265 encodes often seem to be much smoother than in x264 ones, even without SAO enabled.

EDIT: I think you mean --selective-sao 2? Option 3 enables SAO for all reference frames.
