Quick answer

Which Optim release should I use?

Updated last month
Latest stable file v1.15.0
Game version 26.2
Loader Fabric 0.19.3

v1.15.0 is a complete pack release for 26.2 with Fabric 0.19.3. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 68 mods in this pack file.

Pack setup

How should I set up Optim for players and a server?

Use v1.15.0 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 v1.15.0
Dedicated server setup Match v1.15.0
Pack loader Fabric 0.19.3

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 68
Client only 51
Server only 0
Not labelled 17

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 Optim?

v1.15.0. Change the pack release and its contents or setup may change too.

68 mods in this pack file

The selected pack release is v1.15.0. That file is for Minecraft 26.2 with Fabric 0.19.3. It contains 68 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.

Optim is a Fabric modpack that aims to provide maximum performance with some common quality-of-life modifications to the game. It is a highly opinionated selection of mods I intentionally handpicked to share my improved experience with the wider Minecraft community.


🌟 Features

Main Features

  • Vanilla Parity - Doesn't add any new content to the game as it aims to be compatible with all Vanilla servers.
  • Optifine Parity - Replacements for most Optifine features like Shaders, CEM, CIT, Animated & Connected Textures, Capes, Dynamic Lighting and Custom Sky Boxes.
  • Regularly Updated - Actively maintained and updated to newer Minecraft versions.
  • Optimized - Strives to provide the best possible performance while still having all the bells and whistles.

Other Features

  • Replay Mod - The best way to record and capture replays.
  • Roughly Enough Items - The go-to mod for browsing receipes.
  • Auth Me - Has your client been launched for too long? Use the authenticate button in the server list. No need to restart.
  • Improved Third Person - Minecraft's third-person mode is old and clunky, the new one allows you to turn the camera without turning your character.
  • 3D-Skin-Layers - Makes skins look fabolous by improving rendering of the 3D layer.
  • Wavey Capes - Capes now blow beautifully in the wind.
