Strange texture appearance on ATI Radeon 9500+ and X500+ 

This problem happens when the object is seen from far away, then the texture becomes clear when the object is seen from close-up.

These families of cards support Not Power Of Two Textures (NPOT) but have problems if mipmapping is being used with them (as discussed here).
 
By default Eyeshot uses mipmapping as the texture minifying function, so this problem can arise.
 
To fix it, resize the texture used in the material to power of two dimensions or set the
 
Material.MinifyingFunction = textureFilteringFunctionType.Linear;
 
for the material that has the NPOT texture
