'''The three algorithms are different only for the alpha channel compression, the RGB part is exactly the same for all three'''. So if you don't need alpha blending you should use DXT1, as using DXT3 or DXT5 will only double dds file size without any improvement in visual quality. Instead, I regularly find out in texture replacement lots of DXT5 compressed textures with the default white alpha channel. | '''The three algorithms are different only for the alpha channel compression, the RGB part is exactly the same for all three'''.

Wel, I think there is no need to eplain this | |||
