About this Modpack

Welcome to FPS+

This is 'FPS+', a modpack I put together to make Minecraft as smooth as possible.

Please do NOT redistribute.

Vanilla VS FPS+

Between Vanilla and FPS+, FPS+ has a higher increase in FPS than Vanilla by 187% on Maximum settings.

It should be noted that the FPS shown in Gallery would often fluctuate on both versions, and the highest results could only be achieved by standing perfectly still.

I have an RTX 3050 Laptop 8GB RAM Intel Core 5

Essentially if your system is better than mine, your system should run this the same/better.

IMPORTANT:

A mod in this modpack known as Nvidium is INCOMPATIBLE with Shaders, but Shaders are still safe to use as Nvidium will simply disable itself. Shaders were not tested for this pack.

CREDIT:

This modpack uses a fork of Nvidium for the latest version.

How to Set Up a FPS+ Server

Order Server

Open the modpack browser in the dashboard, search for "FPS+" and click "Install". The fabric loader and Minecraft 1.21.11 are configured automatically.

Start Server & Play

Start the server – all mods are loaded automatically. Share the server IP with friends and play together!

Frequently Asked Questions

FPS+ 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 FPS+ 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 FPS+ 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.

FPS+ 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.
