Optimization Foundation is a performance modpack that is designed for other creators, and for players who want a smooth vanilla minecraft experience.
I created this pack because I was tired of getting around 20 FPS while playing modpacks on a low-end PC or laptop.
My goal is to build a perfect performance foundation so anyone can enjoy larger modpacks with smoother gameplay, and so that I can play a big modpack without lag for once.
Features:
- Higher FPS
- More stable tick rates
- Faster chunk generation
- Fixes for bugs, crashes, and memory leaks
- Faster game startup
- Faster structure and biome locating
Note:
- Bug reports, suggestions, and feedback can be posted in the comments for now.
- Feel free to use this as a foundation, you don't have to credit me or ask for permission.
This modpack aims to include every optimization used in large modpacks. If you think something is missing or can be improved, please let me know.
