If you AA is set to 16 and it still looks like that, maybe your unity is playing up?
You could try the edge blur image effect.

what do u mean by “unity is playing up” ?

and this luminous edge blur image effect, what exsctly setings shall i keep of radius size and blur radius ?>?

perhaps if you truely are in forward rendering… maybe check your options again… maybe you set the aa to be running at fantastic quality, but maybe the editor isnt using fantastic quality.

I think the problem in rendering path
If you in Deferred rendering, the AntiAliasing is impossible there, so you need to switch to a Forward rendering
See this page:

But can be another problem: You changed AA value in setting option, but you havnt enabled that option for editor, switch Editor quality to fantastic. Visit this page:

or you just import the pro shader package and use the alternative AA shaders present in there in 6 forms (if you can switch to deferred you are on pro)
