About this Modpack

🪶LightlyOptimized • Modpack

This is a simple and lightweight modpack, allowing you to optimize and run Minecraft on old or low-end computers without lag! With the support of shaders and a supply of optimization, it satisfies RAM Usage and CPU, typically by lowering them, boosting the FPS substantially. This is highly-configurable, flexible, and seamless.

It is also satisfactory to use RTX shaders on high-end computers. The purpose of the modpack is to bring a spotlight on its appealing appearance, balancing its performance.

⚠️ Critical Information

If you want the leaves to look like other modpacks, disable Cull Leaves pack.
Cull Leaves make it look like OptiFine Smart Leaves.
This modpack also has MoreCulling so disabling cull leaves will enable this.
Both mods have same performance just different look.

❓Why this and not optifine

Optifine has got very outdated tweaks and it breaks with some modern mods. Also it doesnt improve frame rate much in modern computers.

How much RAM does a Lightly 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 Lightly 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.
