I went through every piece of art in the mod and adjusted the resolution to something reasonable, 256x256 for units (civ4 uses 128x128) and 128x128 for buildings. Some of the textures we were using, especially those we imported for other games, were huge. Its especially nice considering we have about 30 meg of new art in 0.41 that wasn't in 0.40. So I really reduced about 100 meg worth of art. It will also be easier on graphics cards, smaller textures mean less video memory. We are still going to be significantly higher than Civ4, but at least now we are spending the memory on things you actually appreciate.
