About this Modpack

I was sick of all the optimisation Modpacks I found including non-optimisation-based, intrusive mods, so I took it into my own hands and created a modpack that improves and optimises the game without adding any intrusive features

Optimisations include:

All compatible sodium mods
Iris
client-side Noteblocks to remove lag when listening to Noteblock music (especially useful on large servers)
Bad optimisations to optimise non-visual related features
Chunky for better chunk management
Entity culling
Fast quit
Dynamic FPS so AFKing won't eat your resources
Noisium for better terrain gen
Server ping fix
No texture pack reload screen
Optimised player rendering (especially useful on large servers)
Render distance beyond that of the server
Asynchronous pack scan for faster texture management
and much, much more

Frequently Asked Questions

OnlyOptimisations 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 OnlyOptimisations 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 OnlyOptimisations without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.1). 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.

OnlyOptimisations 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.
