Aliased edges on hi-res material settings

Good afternoon all,

    Sill learning the basics via tutorials and documentation, but i've not yet come across anything that explains why, inspite of a high tessalation value, HQ blur node on my shapes, hi-res plane object, I am still getting aliased edges in my 3D view.  At this point is it simply as basic as the 3d viewport focuses a high quality preview on the part of the model closest to the virtual camera, and then lowers tesselation for the part of the object further back in space?  I feel like in tutorials I don't see jagged edges in the material author's work, even in the building process.  I've attached a shot of the settings I believe are most relevant, aware that I could be missing something major.  I'd prefer not to add many hq blur nodes in my graphs if possible.
