If you would like a more put-together, vanilla compatible optimization modpack, try my other one called Beautifully Optimized. <3

Beautifully Optimized: link

This modpack is not vanilla compatible!

If you do download, it has this:

Performance Improvements

Features a collection of over a dozen mods to significantly improve performance, such as Sodium and many others to work together to improve world loading times, frames per second, tick speed, singleplayer & multiplayer performance.

No Optifine Required

The bundled mods replace all the various features that Optifine gave, such as Iris for shaders, zoom, connected textures, entity texture fixes.

Many Quality-of-Life Additions

On top of the performance improvements, this modpack implements a few tweak mods that help Minecraft feel smoother, ranging from simple mouse tweaks, small animation overhauls, to many new structures to encourage exploration, with many new overhauls of biomes, structures, with many new mobs to see and defeat!

Improve The Look Of Minecraft

The modpack adds a few small adjustments to make Minecraft look greater than it already does, such as having animations to chunks, new player animations, more details to skins, and small visual overhauls to things like capes. There are also shader options available.

Happy Minecrafting! <3
