About this Modpack

Notice: I lost motivation to maintain this modpack. I might continue it at some point but for now I would recommend Fabulously Optimized instead as it does the same thing but better.

A simple, performant optifine replacement modpack designed with performance and compatibility in mind.

Missing animated, connected, and custom item textures.

What does it do?

Serotonin attempts to replace as many optifine features as possible while having better performance than vanilla or with optifine. It also tries to add small features that could be useful without being overpowered or cheaty, much like optifine used to.

Why should I download it?

Serotonin is aimed to be familiar to optifine and vanilla players in a way that few other modpacks are, and is preconfigured to nearly replicate optifine's default settings. It also improves performance more than optifine and on par with other modpacks that do similar things.*

Overall, its your choice whether you use serotonin or not, because there are a lot of other good modpacks that do the same. I hope you can try it though, because I put a lot of effort into it!

*Not yet tested or confirmed, this claim is a estimate.

Frequently Asked Questions

[📦] Serotonin 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 [📦] Serotonin 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 [📦] Serotonin without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.20.4). 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.

[📦] Serotonin 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.
