Optimization of the images!

i tried all of the shaders but images are not smooth and i dont know why. their shapeness are so high, i guess. i upload an image for understand me. The red box is the just an example too understand me. it is more shape in the unity, this is more smooth but actually it is not.

Add Antialiasing effect to your camera http://docs.unity3d.com/Documentation/Components/script-AntialiasingAsPostEffect.html
:wink:

is this okay for android mobile cpu?

I think this mean that antializing is supporting on devices wich support OpenGL ES 2.0.
