    We don't need more standards. We just need better optimizing exporters. PNG is capable of better compression than most programs export at. Ken Silverman's PNGOUT is an excellent example of this.

    https://en.wikipedia.org/wiki/PNGOUT

    Below are the results of running the program on the individual maps of the following free texture at 1K resolution.

    https://texturehaven.com/tex/?t=grass_path_3

    AO -> 570,604 -> 449,584 (22% reduction)
    Bump -> 913,190 -> 850,622 (7% reduction)
    Diffuse - 2,214,702 -> 1,888,503 (15% reduction)
    Normal - 1,922,140 -> 1,914,111 (1% reduction)
    Roughness - 798,796 -> 770,372 (4% reduction)
    Specular -> 573,052 -> 551,742 (4% reduction)

    Oddly it refused to process the displacement map claiming it was an unsupported format regardless of resolution.
