Before using Raven Client, learn how to configure it below!

Guide

First of all, do not disable/delete any mods. They are all required, but can be turned off if you follow the steps below.

  • Run Minecraft
  • Click Mods
  • Hover over ModSets
  • Click the Configure icon
  • Disable/enable any features you want from there.

Note: if you disable or delete any mods, you won't be able to open the 'ModSets' configuration menu. If you want a mod to be able to be toggled, request a feature here.

What is this?

Raven Client is built directly off of my modpack OptiFine for Fabric. It includes extra features that are essential for gameplay such as low fire, low shield, no darkness, connecting to any server version, and so much more!

Why Raven Client instead of others?

Raven Client is modular. This means that it is VERY customizable. Only essential mods are enabled by default, and the more game-changing ones are left disabled. This allows for a wide range of playstyles, from a beginner to Minecraft, to a long time player, to someone switching clients!
Raven Client is also extremely performance focused. When using Raven Client, I get over 2x the FPS than when using OptiFine!

Here is how many FPS I get using OptiFine:

Frequently Asked Questions

Raven Client 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 Raven Client 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 Raven Client without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.4). 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.

Raven Client 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.
