Quick answer
Which JS Performance Core release should I use?
beta file JS Performance Core 26.2-1.0.0
Game version 26.2
Loader Fabric 0.19.3
JS Performance Core 26.2-1.0.0 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. 15 mods in this pack file.
Pack setup
How should I set up JS Performance Core for players and a server?
Use JS Performance Core 26.2-1.0.0 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 JS Performance Core 26.2-1.0.0
Dedicated server setup Match JS Performance Core 26.2-1.0.0
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 15
Client only 8
Server only 0
Not labelled 7
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 JS Performance Core?
JS Performance Core 26.2-1.0.0. Change the pack release and its contents or setup may change too.
The selected pack release is JS Performance Core 26.2-1.0.0. That file is for Minecraft 26.2 with Fabric 0.19.3. It contains 15 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 JS Performance Core?
JS Performance Core
This modpack aims to make Minecraft playable again on "potato" computers. It contains only the bare minimum required for performance. Because of this, you won't find mods like Iris here. If you are looking for "Quality of Life" modpacks, I don't have any yet—but they are coming soon!
Features
- Maximum Optimization: Built on the latest Fabric loader with essential mods like Sodium, Lithium, and FerriteCore.
- Smart Culling: Aggressive culling of hidden objects and particles to save GPU resources.
- Vanilla-Friendly: No gameplay changes. It’s the Minecraft you know, just much faster.
- Lean & Clean: No Iris or shaders are included by default to keep the pack as lightweight as possible.
