About this Modpack

Perfectly Optimized

Welcome to Perfectly Optimized, where I've made the most common versions of Minecraft run as good as possible. I've tested these with my friends who all run low-end PCs/Laptops, so hopefully these can help you out!

P.O is meant for anyone who want's a simple optimization pack, with a few of the small qualities of life. This will include all the optimizations, many different shaders to try, and basic mods for assisting in multiplayer & managing all your mod settings.

HEADS UP!

Absolutely NONE of the mods/shaders added in this modpack are mine, and are all listed and credited below this message. I have just put together all these into a modpack that runs well.

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 Perfectly Optimized (P.O) without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.10). 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.

Perfectly Optimized (P.O) 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.
