Pack setup

How should I set up Flawlessly Optimized for players and a server?

Use 1.2.3 for 1.21.1 (Sodium 0.5.11 Latest) 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 1.2.3 for 1.21.1 (Sodium 0.5.11 Latest)
Dedicated server setup Match 1.2.3 for 1.21.1 (Sodium 0.5.11 Latest)
Pack loader Fabric 0.16.10

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.

Plan the server requirements Read the Minecraft installation guide
Referenced mods 47
Client only 36
Server only 1
Not labelled 10

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 Flawlessly Optimized?

1.2.3 for 1.21.1 (Sodium 0.5.11 Latest). Change the pack release and its contents or setup may change too.

47 mods in this pack file

The selected pack release is 1.2.3 for 1.21.1 (Sodium 0.5.11 Latest). That file is for Minecraft 1.21.1 with Fabric 0.16.10. It contains 47 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.

  • x: MAJOR version (1.21 was 1.y.z, 1.22 was 2.y.z)
  • y: MINOR version (Big updates - Mod addition/removal)
  • z: PATCH version (Small changes - Micro Config Update,Mod Updates)
  • pre-release: For untested,breaking changes,not ready for use versions (Values: alpha,beta)
  • the MC version taken is the minor release the version of Flawlessly Optimized is for.

x.y.z is reset to x.0.0 for every new MC release as different MC versions are very likely to have different mod sets available for them.
