NOTES: Normal Maps don't necessarily need to be saved as DXT3, you can save a normal map as DXT1 No Alpha if you don't need the alpha channel.

This will give you a smaller file, with no gloss effect whatsoever though.

DXT5 can also function as a normal map format, without putting a noticeable step in the alpha specular map's grayscale gradients.  This also goes for alpha channels in color maps used for transparency or parallax displacement.
DXT5 can also function as a normal map format.  DXT3 uses an Explicit alpha map, which has a noticeable step in the grayscale gradients of the mapDXT5 uses an Interpolated alpha map, which does not have this step and may be better suited for some situations.
