Soft Shadows look terrible

I have been messing around with a bunch of the soft shadows with directional lights, but no matter what I have tried (various combinations of resolution, strength, bias, softness and shoftness fade) , they look terrible (see the picture). Is there some type of setting that I am missing that fixes the graininess?

EDIT: So apparently, Unity thinks this is “good”… http://forum.unity3d.com/threads/162791-Soft-Shadow-Jagged-Edges

So if you want good dynamic shadows, don’t use Unity’s. Good lesson to learn here. Are there alternatives to good looking soft shadows that are not too demanding?

I dont know much about lightmapping. Or unitys.

BUT raycasted soft shadows can have graininess (which is what that looks like) if you dont sample enough.
