Antialias LineRenderer Lines

Is it possible to make the lines from Line Renderer less jagged - antialiased? By default, and even with `lineRenderer.material = new Material (Shader.Find("Particles/Additive"));`, curves, straight lines - they all have jagged edges.

I have used this way:
Add new LineRenderer to MainCamera and assign to it the Default-Particle material from standart set.
Then make it invisible this way: Position->Size <= 1
And use material from it:

mylinerenderer.material=maincamera.GetComponent<LineRenderer>().material; 

It’s look better than

mylinerenderer.material=new Material (Shader.Find("Particles/Alpha Blended Premultiply"));
