The differences in memory consumption of DXT2/3 vs DXT1 are due, IIRC, to the
driver not compressing textures <= 128x128 pixels. This was noted by a couple
people (I can't recall where) with Quake 3, which was using hardcoded DXT1,
which resulted in unpleasant side-effects with lightmaps, where the texel
density is appreciably low in-game, exaggerating the compression artifacts.
Someone made a hack that patched Quake3.exe to use DXT2 and the quality was
much closer to uncompressed textures.
