About this Modpack

Withered Utils is a optimization modpack that doesn't change vanilla content and adds many useful tools.

26.1.2 alpha will be available soon.

It lets you play on any server thanks to ViaFabricPlus but beware of the servers rules, some of the mods features might be considered cheating.

Performance

It includes the usual performance mods you can find on modrinth's first page but also less known ones like Better Block Entities.

On a gaming laptop with a Ryzen 5 7535HS and a RTX 3050 4GB it gets 300-350 FPS without shaders and 80 FPS with BSL at medium setting (16 chunks).
Nvidium 1.21.10 is from drouarb/nvidium.

Also works on Mobile Launchers; a GalaxyA14 using MobileGlues with ANGLE as OpenGL ES Driver gets stable 60 FPS without shaders (8 chunks).

Frequently Asked Questions

Withered Utils 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 Withered Utils 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 Withered Utils 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.

Withered Utils 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.
