Vibrant Visuals
Vibrant Visuals are Minecraft’s new built in Shaders.
Vibrant Visuals may impact the current state of the modding process and gameplay in particular for Shaders.
Minecraft’s developers intend to rewrite some parts of the rendering process adding more graphic specific code to adapt and prepare the game for Vibrant Visuals. Shaders will become way better, less laggy and less CPU costly because they will be supported by the Vanilla engine and maybe Shader loaders will not be required anymore.
In general all Mods will benefit with a faster and better graphic experience.
