atom
lightweight optimization modpack with maximum output
Quick answer
Which atom release should I use?
atom 1.2.0 - Fabric is a complete pack release for 1.21.1 with Fabric 0.16.9. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 25 mods in this pack file.
Pack setup
How should I set up atom for players and a server?
Use atom 1.2.0 - Fabric 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.
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.
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 atom?
atom 1.2.0 - Fabric. Change the pack release and its contents or setup may change too.
The selected pack release is atom 1.2.0 - Fabric. That file is for Minecraft 1.21.1 with Fabric 0.16.9. It contains 25 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.

Tests
🖥️GPU - GeForce GTX 1050 🧮CPU - Intel(R) Core(TM) i5-7300HQ CPU @ 2.50GHz 2.50 GHz 📟RAM - 16GB
Known Problems/Incompatibilities🧱
well for now there's only one significant problem at the moment, and that's the Cyrillic support in ModernUI,
If you don't like the smooth font, you can disable it by going to Ctrl/⌘+K>Preferences>Text Layout>Default Font Behavior and set Keep All, but then the Cyrillic text will look like empty space, so the only way to fix it is as follows:
- stay with the smooth font
- disable the new text engine by going to Ctrl/⌘+K>Options>Extensions>Modern Text Engine and disabling it, but then things like emoji and markup won't work
