Both fed user-written GLSL to the backends at runtime, which the move to bytecode emitted straight from the shader generators leaves no compiler for. The frontend's own shader pipeline covers post-processing. The presentation pass keeps a plain copy and the built-in correction shader for output resampling, colour space and gamma correction and HDR scaling, now compiled in rather than loaded from Sys/Shaders. The graphics-mod system keeps its draw, EFB, projection and texture actions; custom pipelines, materials, shader, mesh and sampler assets, the custom constant buffers in every backend and the two mods built on them are gone, along with the shader generators' custom-shader hooks.
