About this Modpack
The main purpose of this modpack is to provide a stable and useful template for building your own optimized Minecraft experience.
YOU MAY NEED TO TWEAK AND TUNE BASED ON YOUR SYSTEM
The pack works well out of the box, but for a better experience i recommend all to try out different settings and functions to see what works best. Better yet, make your own copy of the pack and change out the mods themselves to your own liking.
The focus of this pack is pure and raw performance, making sure that you will be able to run Minecraft on any system. This is ideal for laptop gamers, or gamers with low-end hardware. This was itself the inspiration for making a performance modpack, seeing as i myself want to play Minecraft on-the-go.
