About this Modpack

This is a modpack that adds only client-side mods that improve graphics, sound design, performance, and QoL.
It is meant to be a better way to play vanilla minecraft, not to make it too easy or to cheat.

Players using the Ultimate Client should still be able to join any vanilla servers!

This ModPack will come with shaders disabled out of the box; This is to increase compatability with weaker/mobile PCs.
You can always Toggle them on with [k].

Performance can be seen in the gallery, all screenshots taken with the same computer in the same world.
I recommend allocating at least 4GB (4096MB) of RAM to your instance

I have not had any issue playing on various servers with anticheat, but, while it is the intention, I cannot guarantee that this ModPack is fully multiplayer safe.

Frequently Asked Questions

Ultimate 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 8 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 Ultimate Client server really need?

Minimum 6 GB, recommended 8 GB for stable performance. per 5 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 €12/month).

Can I add custom mods to Ultimate Client 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.

Ultimate Client server lagging – performance tips

1) Increase RAM to 8 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.
