About this Modpack

Optimised Timely — OpTimatic

OpTimatic is a QOL-focused Minecraft modpack built to improve the overall gameplay experience through carefully selected quality-of-life and optimization mods.

The pack focuses primarily on usability improvements that make Minecraft smoother and more convenient to play, while still including performance optimizations to help the game run more efficiently. The goal is not to heavily modify Minecraft, but to refine the experience with tools and improvements that feel natural to use.

OpTimatic is a client-side modpack, meaning it does not change vanilla gameplay or server mechanics. You can join most vanilla or modded servers normally without requiring the server to install the pack.

The name OpTimatic comes from Optimised and Timely, reflecting the core philosophy behind the pack:

Optimised — a collection of mods chosen to improve stability, usability, and performance.
Timely — kept up-to-date with the latest Minecraft versions whenever possible.

Because OpTimatic includes many quality-of-life features alongside optimization improvements, it is best suited for players with a moderately capable system rather than extremely low-end hardware.

If your main goal is maximum FPS and the lightest possible setup, you may want to try the lighter version of the pack instead: OpTimatic-Lite

The goal is simple: provide a modern, convenient Minecraft client that improves the way the game feels to play while keeping the core vanilla experience intact.

Frequently Asked Questions

OpTimatic server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a OpTimatic server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 8 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €8/month).

Can I add custom mods to OpTimatic without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.11). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

OpTimatic server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
