Lrbium (aka lebium)
small inside joke between my friends
this modpack keeps core gameplay like vanilla while adding a lot of performance features, some Bug Fixes and Quality of Life features without trying to reduce performance
this modpack (in theory) should be compatible with vanilla servers and allow vanilla players to join if you host a server with this modpack
What this modpack will add for example- c2me really awesome chunk performance mod that optimizes chunk loading
- zoomify really awesome zoom mod
These mods don't modify core gameplay (see below), but do add Quality of Life and performance improvements, and generally don't impact performance
What this modpack wont add for example- tom's simple storage
- Wavey Capes While this doesnt modify gameplay, it does have a slight performance impact
Mods like these will not be added since it modifies core gameplay, or impacts performance (i'm not saying these are bad mods)
