If you want a modpack that enhances your vanilla experience to a new level without taking anything away from the base game. This is a collection of Fabric mods put together to enhance the Minecraft experience without taking away from it.
Mods like Iris allow you to utilize shader packs to visually enhance your game to a whole new level, while keeping performance good. Jade is the successor to WAILA, which lets you see information like name, and mod origin of the blocks you look at. Sodium, Lithium, etc all help boost performance in the game, whether through the graphics, networking, etc.
No resource packs or shaders come preloaded with this mod, but most shaders work great.
