About this Modpack

StupiClient

is a Modpack for everyone who wants to have the best possible performance in Minecraft. It was mainly intended for the "StupiCraft" my own SMP-Server where I play with my friends. But they wanted me to upload "StupiClient" because they really liked it and so I did.

The modpack is recommended for everyone, who wants to have a nice experience in Minecraft. You will get some features like shaders and zoom. Redstone will be much easier because of veryiose tweaks. You can sort chests and everything with only one click.

One of the big advantages of the Modpack is that it is fram a small developer and receives a lot of love.

The big Mods

Sodium - The fastest and most compatible rendering optimization mod for Minecraft
tweakeroo - Various client-side tweaks, such as hand restock, hotbar swap/cycle, flexible/fast block placement etc.
Iris - A modern shader pack loader for Minecraft intended to be compatible with existing OptiFine shader packs
CraftPresence - Completely Customize the way others see you play in Discord!
Nvidium - Fast nvidia only rendering engine for sodium (Not updated anymore)

Frequently Asked Questions

StupiClient 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 StupiClient 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 StupiClient without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.11). 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.

StupiClient 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.
