List of Performance Mods

Below you'll find a helpful list of mods sorted by 4 categories: Lag Diagnosing Mods, Tick and Backend Performance Mods, Client and Graphical Mods, and Rendering Overhauls. For more information on which you need and what kind of lag you are experiencing, check out our lag article here.

Lag Diagnosing Mods

These mods are great at finding sources of server/TPS lag. The mod name of each is linked to support articles that explain how to use them.

Tick and Backend Performance Mods

Tick and backend performance mods are mods that improve the overall performance of modpacks or servers. They are usually installable on both client and server, or sometimes just the server. They help improve the TPS. These are often good for server-side lag and some client-side lag.

Client and Graphical Performance Mods

All mods in this list are client-only. Client and graphical performance mods help improve your FPS, improve load times, or help cut down on memory usage on your local game on your computer, but cannot be installed on a server.

Rendering and Lighting Overhauls

All mods in this list are client-only. Rendering and lighting overhaul mods are complete revamps of Minecraft's rendering. Most of them add many extra graphics settings and drastically improve FPS. Plus, many of them allow for the use of shaderpacks. Two rendering overhauls cannot be used together, the same as two lighting engine overhauls. Make sure to read the curseforge description page for compatibility notes and instructions!
