Simple uPack
The simplified version of uPack by CtrlUser.
About this Modpack
This mod pack is a cut down version of my other mod pack, uPack.
This version focuses much more on performance, but still has some QoL features.
Suited for low-end devices.
Server Usage:
THIS MOD PACK MAY NOT BE ALLOWED ON SOME SERVERS, DUE TO MODS LIKE "GammaUtils". PLEASE CONSULT WITH STAFF ON THE SERVER YOU'RE TRYING TO PLAY TO SEE IF THESE MODS ARE ALLOWED! I'LL NOT BE RESPONSIBLE FOR ANY BANS HANDED OUT BY USING THIS MODPACK!
Features present:
OptiFine Resource Pack Support
Fast World Quitting
Optimizations ranging from NBT handling to world rendering, and more!
Joining servers with different versions
Singleplayer Server (world) optimization
8-bit resource packs
Extra features for Sodium
Memory Optimizations
Handling Cullings effectively
Reducing FPS when not needed, eg. having the game minimized.
Faster mathematical functions.
Particle improvements.
Detailed Block Viewer
Features Removed:
Shader Support.
Many QoL mods.
Dark Mode.
Optimizations that have effects on uncommon elements.
Darker Loading Screen.
Dynamic Lighting.
Voice Chat.
Redstone QoL.
... and much more!
As mentioned earlier, devices not being able to run "uPack" smoothly due to it being heavy, should run this one much smoother. Essential QoLs (in my opinion) have stayed in this pack.
As always, please support the developers/creators of the mods and resource packs, not me!

Frequently Asked Questions
Simple uPack 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 Simple uPack 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 Simple uPack 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.
Simple uPack 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.
