About this Modpack

OptiPack

QOL Optimisation Pack

OptiPack has long been a private pack of mods I have collected for my friends, most of whom play Minecraft on computers with processing power rivaling that of a potato (looking at you Wulfian!)

It is a pack that has been fine-tuned to fit our play style. I started making the pack as I wanted my friends to use the Fabric mod launcher, but still have all the features of OptiFine, but overtime was expanded to have other mods that would improve our gameplay experience, and deal with common gripes and problems we would encounter with the base game.

Frequently Asked Questions

OptiPack 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 OptiPack 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 OptiPack without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.20.6). 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.

OptiPack 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.
