Both GLSL and HLSL are very popular, for both 64kB intros and 4kB intros. Even Elevated is storing the actual text in the binary (http://www.pouet.net/prod.php?which=52938 http://www.pouet.net/prod.php?which=52938). Compressed text can be quite small. I wrote a minifier specifically for these use-cases and it has been used in many demoscene productions: https://github.com/laurentlb/Shader_Minifier https://github.com/laurentlb/Shader_Minifier On a 64kB intro like Guberniya, it can save a few kilobytes (but size was not an issue for them) - after compression.
