In SR13 we are now using mipmapping on all texture and decal mappings. This means that noise in the rendered texture is minimized, even when looking at the texture from far away, or at glancing angles.
From the picture is looks like you have a texture which is quite noisy, especially when looking at it from far away. Mipmapping alleviates this effect, just like our human eyes smooths out noise when viewing detailed things from afar.
If you want the bottom picture to look more like the top one, you need to increase the scale/size of the texture so that the noise detail is large enough to be seen from a distance, if that makes sense.
