Hi, i hope that this wasnīt posted earlier. I found out that GStudio canīt handle .dds maps correctly, because if i use a material f.e. mtl_specBump then the specularity pixels (i hope you understand what i mean) But itīs not the resolution of the textures, because it also happens at High-res textures Here are some pictures:    right-click -> show picture for bigger size

You could try 3Dc. Or use DXT5 and save the x component of your normalmap in the rgb-channels and the y component in the alpha channel. (The nvidia dds plugin for photoshop can do both automatically). You would have to modify your shader (for the DXT5 method) from:
float3 normal = tex2D(normalmap, In.Tex)*2-1;
to
float3 normal;
normal.xy = tex2D(normalmap, In.Tex).ga*2-1;
normal.z = sqrt(1 - normal.x*normal.x - normal.y*normal.y);
