preloadGfxAssets(); Many mod loaders support a pre-gfx phase. Example using a Fabric mod (Minecraft):

// Now initialize graphics initWebGL();

If you’ve come across the term “Code-pre-gfx Download” in documentation, forums, or build scripts, it generally refers to fetching or preparing graphical assets (textures, shaders, fonts, or sprite sheets) before the main graphics pipeline or rendering engine initializes.
