About this Modpack

INFO

This modpack is made to boost your fps, so you can use it to boost your fps. The only mod that doesn't contribute to more fps or is dependency is iris shaders. This pack is client side, but some of its mods will work on the server side as well. Use this if you want better performance in minecraft. It also contains a shader and a nice texture pack. You can use this as a base for your modpack. More mc versions will be added in the future.

PERFORMANCE

This modpack boosts the performance by a ton. In a big storage room, my fps without any mods was 200-300(with default settings and 16 chunks). With the modpack it increased by ~640%, going to around 1700-1950 fps. Because I have a decent pc, I can use shaders, and with shaders my pc gets around 120-180 fps with 12 chunks and 80-110 with 16 chunks(with complementary unbound ultra preset).
Without the modpack here I get 314 fps:

How to Set Up a FPS++ Server

1

2

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 €5.2/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 (1.21.8). 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.
