About this Modpack

Triple your FPS with Mostly Optimized!

Here's what it does:

Mostly Optimized attempts to make minecraft be less laggy, have higher FPS, reduce lag spikes, load chunks faster, create worlds faster, and replacate every feature from Optifine. Some of those features are shaders, zooming, dynamic lighting, removing fog, fullbright, custom entity models, custom capes, higher render distance, better grass, randomized textures, Configurable animations and details, connected textures, and more, so if a resource pack or a mod says it requires Optifine to work you can get it working in Mostly Optimized! I also included some mods I personaly use but I tryed not to change to many vanilla mechanics, and if you don't like a certain feature in this modpack feel free to add or disable any mod/resource/data/shader pack you want to have the experience you want! . Thank you to Fabulously Optimized and Vanilla Perfected for the inspiration!

Frequently Asked Questions

Mostly Optimized (FABRIC) 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 Mostly Optimized (FABRIC) 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 Mostly Optimized (FABRIC) without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.1). 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.

Mostly Optimized (FABRIC) 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.
