About this Modpack

OptiPrime is a pre-configured client modpack built to reduce RAM consumption and increase framerates (FPS). It functions as an open-source alternative to OptiFine.

Functional Features

Pre-assembled: A ready-to-use mod list. Requires no manual searching or testing of individual mods.
Resource Management: Lowers memory allocation and stabilizes frametimes across different hardware setups.
Open-Source Base: Compiled entirely from open-source projects, ensuring technical transparency and rapid updates.
Multi-Loader Support: Actively maintained for NeoForge, Fabric, Forge, and Quilt.

Technical Foundation

Performance is achieved through a specific set of mods (exact list varies by loader and game version):

Rendering: Sodium / Embeddium alters chunk rendering logic to increase FPS.
Memory: FerriteCore and ModernFix reduce RAM usage and patch vanilla memory leaks.
Culling: EntityCulling and MoreCulling skip the rendering of unseen entities and blocks to save CPU cycles.
Shaders: Iris / Oculus provide native compatibility for shader packs.

We maintain the modpack across the following game versions:

How to Set Up a OptiPrime Server

Order Server

Choose at least 4 GB RAM (6 GB recommended for OptiPrime). Based on player count: per 5 players.

Install Modpack in Dashboard

Open the modpack browser in the dashboard, search for "OptiPrime" and click "Install". The neoforge loader and Minecraft 26.1.2 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

OptiPrime server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong neoforge 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 OptiPrime server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 5 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 OptiPrime without conflicts?

Yes, but check compatibility: only use mods for the same loader (neoforge) and same Minecraft version (26.1.2). 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.

OptiPrime 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.
