Problem With Flickering edges

Hello guys i am having a little trouble when i zoom objects with the edges of mesh flickering even if camera is static!
Please help me how can i fix it? and what occurs this problem?
Thanks in advance!

 

First, you have your Game view scale set to 1.37. Stop that. Put it back to 1 or less, unless you want to see the pixels of your rendering. Remember that your players can't do this (well, unless they use a screen-zooming utility, in which case they want to see pixels too!).

Second, that "flickering" is called aliasing. It's normal, and won't be so noticeable when you don't zoom in. If it really bothers you even at scale = 1.0, then google "Unity antialiasing".

 

I have same issue even without zooming when I move camera there is crazy edge flickering. I use two anti-aliasing method to solve this but still same issue.
