About this Modpack

Sulfur: making your game run as fast, smooth, and stable as possible on the NeoForge loader. Every component in this pack is focused strictly on optimization, reducing stutter and improving resource handling, and keeping performance consistent in all situations.

The pack avoids unnecessary Quality of Life features, prioritizing instead the technical improvements that truly matter for responsiveness and frame stability. By stripping away the fluff, Sulfur significantly decreases memory usage while aggressively improving both FPS and TPS. It remains a lightweight and efficient foundation where every configuration is tuned so the game loads faster, runs smoother, and stays stable even in demanding environments.

Frequently Asked Questions

Sulfur 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 8 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 Sulfur server really need?

Minimum 6 GB, recommended 8 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 €12/month).

Can I add custom mods to Sulfur without conflicts?

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

Sulfur server lagging – performance tips

1) Increase RAM to 8 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.
