They might be larger on disk, but can be compressed further by any archiver thus decreasing the package size, making it better for downloading. Png's as far as I know don't get compressed further. size test: --------------------------------------------------------------------------- iar80 base texture: png texture: size on disk 8.1MB -> targzipped size 8.1MB dds texture: size on disk 21.3 MB -> targzipped size 4.5MB --------------------------------------------------------------------------- complete IAR80 package: png textures: IAR80 zip size: 45MB dds textures: IAR80 zip size: 31.1MB --------------------------------------------------------------------------- (can be reduced further as not all the textures were converted so far).
