Texture blurred

I using texture with size 2x and then scale in Unity to 1x after that texture looks good.

If i using texture with size 1x then in Unity texture looks with blurre effect.

My GUI camera has size = resolution height /2.

On the image first texture has size 1x, second image has size 2x.

Why i cannot use texture with size 1x and this texture blurred?

On the image first texture with size 1x, second image with size 2x.[7529-screen+shot+2013-02-05+at+16.53.26.png|7529]

If the texture will be used for GUI, as it looks like it is, then change the texture type on the import settings of the texture to GUI. This, among other things, will stop Unity scaling it to a power of two.

Also, change the filter mode to bilinear, this will help if you do choose to scale up or down later on.
