    I believe that's just Max sucking noisily at real-time normal-map display.

    What shader are you using? Normal Bump? I've had problems with that in viewport too, not reacting properly to lights. I never found a fix for it.

    I believe Max8 does a lot better in this respect.

    You could also try Ben Cloward's normal map DX9 shader, but that's only a viewport preview, so you can't render it.

    to eliminate a few obvious ones:
    -make sure you use perspective view
    -are you using the viewport directx preview (the pink checker box)?

    I assume you did try to move around the light ?
    In order to see if the normal map is interpreted right. (tangent vs object, x/y or whatever channel flipped etc. )
    Depending on the viewportshader you are using it may be reading normalmaps different from the rendered shader.
    Also you have to set a bitmap for the diffuse in most viewportshaders.

    viewport normal mapping is always painfull...ben cloward might be the best suggestion.
