About this Modpack

Welcome to THE optimization mod for minecraft 1.21.1.

This minecraft mod is the culmination of my research and constant tweaking to make the most optimized version of minecraft you can play, while also improving the default visuals like the fog, clouds, water, particle effects, render distance, and so on.

Here's the frame rates that I normally get when sitting still, at 32 render distance.

Here's my specs if you want to know

i7-7700HQ, GTX 1050TI, 24GB of ram, out of which I only use 4 for MC, and an HDD that I have at most seen running at 10MB/s.

Note that this is just the beta. Expect a lot of changes, things added and removed between versions, crashes, and bugs at every step. I tried to minimize them to a minimum, but there's so much I can see on my own. So if you find anything, tell me, including criticisms.

Frequently Asked Questions

Crownium 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 Crownium 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 Crownium without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.1). 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.

Crownium 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.
