It's like Optifine, but with a little bit (actually, it's more than a bit) of Sodium and more optimization mods.

About this Modpack

Basically, it's a mix of Optifine and most of the modern optimization fabric mods, like Sodium and Lithium...

Also, most of the mods are client-side! (98% of them are client-side)

Also, you can replicate the trailer's graphics!
Aaaand, with the Nostalgic Tweaks (client-side) and the Golden Days Resource Pack (or the Programmer Art Ultimate), you can replicate the old and nostalgic graphic of Minecraft!
Infinite Delay Music!
The chat is more manageable!
Voice Chat! (if you got some friends, you can talk with the Proximity Chat Voice, which is cool, I think...?)

Thanks to all the modders and resource pack-ers!

Frequently Asked Questions

Opti-dium 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 Opti-dium 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 Opti-dium without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21). 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.

Opti-dium 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.
