Different Compressions (.dds)

What are they for? I only use DXT1 ARGB 1 bit alpha and it seems to work ok.
There is a ton of options, like DXT3/5, 3Dc, palette, 8.8.8.8...
If your using GIMP, there is no need to use that just Export it.
 
Basically, compression just reduces the filesize of your textures in exchange for them getting some artifacting and generally just looking worse.

I wouldn't worry about compressing your textures unless you're making some huge total-conversion mod. The difference in filesize will be negligible if all you have in your mod are four icons for a custom civ plus an alpha icon. I've always found that my icons look a lot worse with compression, too.
 
In that case, I'd recommend testing your textures in-game after compressing them with the various methods and see which one works best for you. There were some cases where I'd compress my textures, and then the icons would not appear in a certain size.
 
The decision between the S3 formats is mostly about alpha transparency.

My suggestions:
  • Use DXT1 when there's no alpha.
  • Use DXT3 when there is limited alpha with sharp transitions (e.g., unit textures)
  • Use DXT5 when there are alpha gradients or transparency with rounded edges (e.g., UI elements)
