JEO(Just Enough Optimisations) is a modpack focused on pure performance.
It adds no custom content, it just
makes sure that you get no lag and high FPS.
For modpack developers: You can use JEO as a base for your modpacks, to improve your performance. I only ask that you provide a link back to this page if you go on and publish your modpack.
