About this Modpack

shaders

Functionality

The modpack aims to include the maximum possible performance, by utilizing all compatible performance mods for minecraft 1.21. I have been researching the mods since 1.21's relase and many of the core mods for this project are discontiniued, for this reason, I do not plan on updating it to future versions anytime soon.

What features does it add

It adds proximity chat for supported servers, capes being visible and ~59x more performance.

My experience

This is the modpack I personally use for 1.21 and it got me from 95fps in vanilla to 5593fps with it.

Why you should download it

This is the very best performance improvement minecraft can have and is very difficult to beat.
If you ever wanted to run high end shaders on potato hardware, with this modpack - you can! (not recommended) If you cant even run minecraft on 10 fps on your pc, with this modpack, you can crank the settings up and outclass some high end computers in performance.

the catch

If you decide to use shaders with this modpack, you will soon relise why I do not recommend always using them with the modpack.

Shaders often break the 3d render of the game in such a way where it ghosts a white model of where you look.
More often you will encounter how shaders cause the skybox to render of the wrong size, causing a white cube around the camera.

These bugs happen because of distant horizons.

You also get some artifacts in more distant chunks, this happens because the modpack uses 4 renderers in the backend.

Updates

This modpack will most likeley not be updated for future versions of minecraft for these reasons:

Some mods are discontiniued
Some mods are incompatible in other versions
Some mods are exclusive
Some mods break in other versions
Some mods require libraries that are incompatible
Some mods skip versions

Install Modpack in Dashboard

Start Server & Play

Start the server – all mods are loaded automatically. Share the server IP with friends and play together!

Frequently Asked Questions

Tren 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 Tren 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 Tren without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21). 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.

Tren 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.
