Copium
A Performance and Quality of Life Clientside Modpack!
Copium seeks to fix Minecraft's performance issues, as well as add small features such as Zoom, Shaders, Dark mode, and more! We only use client-side mods, so it should be able to be used on many servers. Note that the pack does include a mini-map mod, so it may not be able to be used on some servers!
What if I want XXX mod added?
Create a Github Issue, and make sure to tag it as Enhancement! Alternatively, simply add it yourself!
Will you port the pack to Forge/Neoforge/Quilt?
No, this pack is exclusively for Fabric, and will stay that way for the distant future.
