About this Modpack
Support for non-fabric modloaders may come.

EssentiallyOptimal Lite is basically just a modpack that logicwise behaves like vanilla, but makes it faster. In testing, I got 144 FPS from letting the game run on it's own. That includes the logic of naturally spawning entities and items as well as the fluids.
For better FPS, go to video settings and slide "Max FPS" to unlimited.
EssentiallyOptimal Lite is liscenced under the MIT Liscense, which can be reviewed here.

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.4). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
