Pack setup
How should I set up Optimally Optimized MC for players and a server?
Use Optimally Optimized MC v2.5 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.
Client instance Install Optimally Optimized MC v2.5
Dedicated server setup Match Optimally Optimized MC v2.5
Pack loader Fabric 0.20.0
A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.
Referenced mods 29
Client only 16
Server only 2
Not labelled 11
These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.
What are the server requirements for Optimally Optimized MC?
Optimally Optimized MC v2.5. Change the pack release and its contents or setup may change too.
The selected pack release is Optimally Optimized MC v2.5. That file is for Minecraft 1.21 with Fabric 0.20.0. It contains 29 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.
About this project
What kind of pack is Optimally Optimized MC?
Optimally Optimized MC
Optimally Optimized MC is a lightweight, performance-first Fabric modpack built for one specific purpose: to maximize your frame rates and obliterate micro-stutters while keeping the vanilla Minecraft experience completely untouched.
Instead of just throwing random mods together and hoping for the best, this pack focuses on a carefully balanced setup that addresses the deepest bottlenecks in the modern Minecraft engine. It runs incredibly well on everything from low-end office laptops to high-end gaming rigs running heavy shader packs.
