thats bull, this texture pack is 16x16, EXACTLY the same as the minecraft official, meaning when a texture from this pack is rendered it still takes the same 16bit rendering, this creates the texture and puts it into view, it does not effect the computer at all unless slowing it down which could be caused from having a different texture pack rather than the official one, because a custom texture pack is rendered from a zip folder whilst the default one is rendered from a convenient Java Class file. :)
