    # There is some incredibly cursed issue with

    # `directx-shader-compiler` flagging up compiler errors only on

    # `i686-linux` and only when it has been compiled with a recent

    # GCC. Since few 32‐bit games are going to use ray tracing anyway,

    # we just disable it for now. Arch has done this since 2022.
