MDU

Players can explore a whole lot of new content and also new dimensions. Lots of structures, features, even dragons can be found (and ridden)! New mobs, bosses, biomes, overhauled stronghold, fortresses, there is a lot of potential for explorers, and these structures give intresting rewards. If you are a builder, you may be intrested in new building blocks, and decorations. There's also an storage system in place to ease up on having gazilions of chests to look around your base for the tons of items that were added.  

Additionaly this modpack contains a lot of optimalization mods, QoL features, as well as some mods that help with server running and managment. Shaders shouldn't be a problem.
