Quick answer

Which Hardly optimised release should I use?

Updated 9 months ago
alpha file Hardly optimised 0.1.5
Game version 1.21.10
Loader Fabric 0.17.2

Hardly optimised 0.1.5 is a complete pack release for 1.21.10 with Fabric 0.17.2. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 19 mods in this pack file.

Pack setup

How should I set up Hardly optimised for players and a server?

Use Hardly optimised 0.1.5 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 Hardly optimised 0.1.5
Dedicated server setup Match Hardly optimised 0.1.5
Pack loader Fabric 0.17.2

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 19
Client only 4
Server only 0
Not labelled 15

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 Hardly optimised?

Hardly optimised 0.1.5. Change the pack release and its contents or setup may change too.

19 mods in this pack file

The selected pack release is Hardly optimised 0.1.5. That file is for Minecraft 1.21.10 with Fabric 0.17.2. It contains 19 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 Hardly optimised?

🚀 Hardly Optimised

The definitive Fabric performance pack for 1.16.5 → 1.21.x

Tested on i5-4570/4GB DDR3/Tiny11 - No theoretical benchmarks!

⚠️ Critical Warning: Minecraft 1.21.5-1.21.7 Unsupported

All versions between 1.21.5 and 1.21.7 suffer from severe Intel GPU freezes (Mojang-confirmed bug).

  • ❌ No longer supported in this modpack
  • ❌ No stability fixes will be backported
  • ✅ Upgrade to 1.21.8 immediately for crash fixes

This is not optional if you use:

  • Intel UHD
  • Any integrated GPU
  • Low-end systems

Continuing to use 1.21.5-1.21.7 may corrupt worlds during freezes.

  • Storage: DRAM-less SATA SSD
