The MCC Island Optimised modpack is built to give a better experience for those who have a 🥔 Potato PC 🥔 including Quality of Life improvements and Optimisation mods!

Minecraft Java in itself is very unstable (FPS) so even if you have a good PC I still recommend you to use these optimisations and if you want to then use this modpack with Lunar Client to stabilise your game EVEN MORE!

Tested with an NVIDIA GeForce GTX 1650 in the most resource intensive space, the Main Lobby:

Vanilla MC (~68 FPS) MCC Island Optimised + Lunar Client + Turbo Entities (~158 FPS)

Frequently Asked Questions

MCC Island Optimised 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 MCC Island Optimised 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 MCC Island Optimised 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.

MCC Island Optimised 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.
