Pack setup

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

Use OptiPrime-NF08-26.1.2 [NeoForge] [26.1.2] 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.

Dedicated server setup Match OptiPrime-NF08-26.1.2 [NeoForge] [26.1.2]
Pack loader NeoForge 26.1.2.95

Plan the server requirements Read the Minecraft installation guide
Referenced mods 23
Client only 8
Server only 5
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 OptiPrime?

OptiPrime-NF08-26.1.2 [NeoForge] [26.1.2] on 26.1.2. The pack contents and setup notes below stay tied to that release.

23 mods in this pack file

The selected pack release is OptiPrime-NF08-26.1.2 [NeoForge] [26.1.2]. That file is for Minecraft 26.1.2 with NeoForge 26.1.2.95. It contains 23 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 OptiPrime?

OptiPrime is a pre-configured client modpack built to reduce RAM consumption and increase framerates (FPS). It functions as an open-source alternative to OptiFine.

Functional Features

  • Pre-assembled: A ready-to-use mod list. Requires no manual searching or testing of individual mods.
  • Resource Management: Lowers memory allocation and stabilizes frametimes across different hardware setups.
  • Open-Source Base: Compiled entirely from open-source projects, ensuring technical transparency and rapid updates.
  • Multi-Loader Support: Actively maintained for NeoForge, Fabric, Forge, and Quilt.

Technical Foundation

Performance is achieved through a specific set of mods (exact list varies by loader and game version):

  • Rendering: Sodium / Embeddium alters chunk rendering logic to increase FPS.
  • Memory: FerriteCore and ModernFix reduce RAM usage and patch vanilla memory leaks.
  • Culling: EntityCulling and MoreCulling skip the rendering of unseen entities and blocks to save CPU cycles.
  • Shaders: Iris / Oculus provide native compatibility for shader packs.

Version Support

We maintain the modpack across the following game versions:
