Information

EssentiallyOptimal adds many mods I reccomend, like Sodium and Essential Mod. This mod is for people who are tired of vanilla or experience too much lag, and want something new and smooth, which this Modpack has!

Technical

Iris shaders ONLY. Do not update Iris or Sodium- doing so will cause the game to crash. If you insist on updating Iris or Sodium, please remove Immersive Portals.

Fabric ONLY- no NeoForge, Quilt, or straightup Forge.

Legal and revenue

EssentiallyOptimal is liscenced under the MIT Liscense, which can be reviewed here.

How to Set Up a EssentiallyOptimal Server

Order Server

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

Install Modpack in Dashboard

Open the modpack browser in the dashboard, search for "EssentiallyOptimal" and click "Install". The fabric loader and Minecraft 1.21.1 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

EssentiallyOptimal 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 EssentiallyOptimal 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 EssentiallyOptimal 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.

EssentiallyOptimal 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.
