About this Modpack

Overview

Client Optimized is a modpack that adds performance, visual, and client-side quality-of-life mods. It does not change gameplay mechanics.

Client-Side Behavior

Most included mods are fully client-side. A few are not strictly client-side, but they do not cause issues when hosting worlds or when vanilla players connect.

Quality of Life Features

The pack includes small interface and usability adjustments that operate only on the client and do not modify world data.

Multiplayer Compatibility

Players can join vanilla servers and most modded servers normally. Some servers may restrict specific features depending on their configuration.

Warnings

Some mods included in this pack may be detected or blocked by server anticheat systems. On certain servers, this can result in kicks, restrictions, or bans. Users should review server rules and allowed-mods lists before joining.

World Hosting

Worlds hosted with this modpack can be joined by vanilla clients without additional configuration.

Intent

The modpack compiles commonly used client-side performance, visual, and quality-of-life mods into one setup.

Frequently Asked Questions

Client 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 Client 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 Client Optimized without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.1.2). 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.

Client Optimized 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. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
