About this Modpack

A new minecraft 1.21 modpack designed for maximum performance.
Onyx is a work-in-progress (not really it already works great) Optimization and Visual Improvement modpack using all the new and best mods for amazingly high fps with or without shaders. On average, with my testing across 3 systems; a random laptop that barely runs windows 10, a windows 11 pc with a ryzen 5 2600 and a gtx 1070 ti, and a windows 11 pc with a ryzen 5 8400f and an rtx 5050, i get 2-3X the performace with shaders, and almost 5x (6x on the best pc) the fps without shaders. of course thats not all, as the tps is also important. in which i consistantly get around 60% lower mspt across all systems. this modpack also beats lunar client and feather client by around 20% each while being easy to install and add to.
(it beat feather by 30% in some cases like singleplayer but in multiplayer only 20%. however; thats still very good).

also comes with controlify for controller support :3

summary: install my modpack its good :)

How to Set Up a Onyx Server

Order Server

Choose at least 4 GB RAM (6 GB recommended for Onyx). Based on player count: per 8 players.

Install Modpack in Dashboard

Open the modpack browser in the dashboard, search for "Onyx" and click "Install". The fabric loader and Minecraft 1.21.11 are configured automatically.

Start Server & Play

Start the server – all mods are loaded automatically. Share the server IP with friends and play together!

Frequently Asked Questions

Onyx 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 Onyx 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 Onyx 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.

Onyx 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.
