Deuterium is a basic modpack that uses Rubidium/Embeddium/Sodium as the main optimization mod, aiming to improve the vanilla survival experience without changing the game's mechanism. It has good scalability, and you can add your favorite mod to this modpack.

Performance

Due to the low compatibility of OptiFine, Deuterium uses Rubidium/Embeddium as the main performance mod and improves the fps while ensuring compatibility as much as possible

OptiFine parity

Supports most Optfine features.

FAQ

Q: What should I do if my game is in Chinese?
A: This is caused by the I18nUpdateMod, which automatically switches the game's language to Chinese upon launch. You can uninstall this mod to resolve this problem, Additionally, you may delete the resourcepack named Minecraft-Mod-Language-Modpack-Converted.zip if it is present.

If you find any bugs or incompatible, please submit them to https://github.com/Ginsway/Deuterium/issues, to help me improve the modpack.

Frequently Asked Questions

Most common causes: insufficient RAM or wrong forge 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 Deuterium 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 Deuterium without conflicts?

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

Deuterium 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.
