About this Modpack

A significantly optimized Minecraft modpack is a curated collection of performance-focused mods designed to dramatically boost your Frame Rate Per Second (FPS) and reduce lag, making the game much smoother, especially on older hardware. Instead of just one big mod, these packs bundle things like Sodium (for rendering optimization), Lithium (for game logic/server-side improvements) and etc together,This mode essentially replace the need for just OptiFine, offering superior performance while keeping the core vanilla look.The goal is to let you play Minecraft comfortably without feeling like you're running it on a "toaster."

Frequently Asked Questions

significantly optimized 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 significantly optimized 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 significantly optimized 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.
