Problem with tga maps

[LDiCesare]

I'm trying to create a map but when I load the .tga file in Dom III, it loses details and precision and becomes ugly: Looks like Dom does not support the ranges of colors I use.
Does anyone know if there's a format limitation, precision or something which limits dom so I could try to save the file from gimp in a format where Dom will be able to display the map properly?

Make sure that you save your files as RLE encoded, I don't know if there are some other restrictions.
