Shouting again from the back row, but I want to point out that
pregenerated mipmaps is not something dds specific, it can be done
with any texture format. It's just about storing them. Like in
http://www.ogre3d.org/tikiwiki/img/wiki_up/MipMap_Example_STS101.jpg .
Of course dds has the pro side that it is loaded directly into memory,
no uncompressing is required. With e.g. png and the storing method
above, the image needs to be decompressed properly to allow using the
mipmaps. But it is possible.
If we figured out a format to store mipmaps and how to use them in FG,
it would allow using many more better filters for them, which might
increase graphics quality a lot, just like was seen in the dds
screenshots. And at the same time could allow for better compression
(but slower loading times maybe) to save HD space if that is
necessary.
Also one thing point mentioning is that DDS format might not be
supported on older hardware. And I think FG is supposed to support
also older hardware.
For reference, the dds loader source:
