About this Modpack

This modpack adds many mods that makes Minecraft survival better, including Sodium, Lithium, FerriteCore, ImmediatelyFast, Xaero's Minimap and Fabric API, and many resource/texture packs and shaderpacks. This is very useful as it boosts FPS, reduces mob tick lag, reduces RAM usage when unneeded, provides a minimap for checking your surroundings for terrain and structures, increases gamma to full, making the dark look like daylight, and even provides the main library for Fabric mods.
