WARNING FOR VULKAN API/MOD
Vulkan may be incompatible with some mods and systems, if the the system was released in 2016 or before. If you want great performance but more compatiblilty, use our Sodium version instead of our Vulkan version for 1.21.5 to 26.1.2! Sodium now support Vulkan starting 26.2!

Answers For The Concerns That May Occur

Simple Questions

  1. Will this improve FPS massively?
    Yes, NanoFabric is focused on massively improving performance, from doing stability increase to FPS increase. For Low to High end PC's users to enjoy. And even for people who can't use Nvidium, the performance will be 2 to 5 times more!

  2. Will it update to the newest version?
    Yes. I'll try and make NanoFabric update to the newest version of Minecraft for you to play.

  3. Will it have Iris?
    Depends on Minecraft version, from 1.21.5 to 26.1.2 you will have Iris to use Shaders but because they won't work with Vulkan API for 26.2+, we will no longer add them to the modpack list.

  4. Is it like those other Optimization modpacks?
    Pretty much... yeah, what am I going to argue? We all do the same purpose by fixing Minecrafts bad performance. We all use the default mods, the only difference we could say is that we focus to be close AS MUCH to vanilla Minecraft while giving best performance.

Safety Questions

  1. Is this safe to use?
    Yes, all of these mods was tested and reviewed to see if its safe or not, if they weren't safe, then they would be removed and will never be added to NanoFabric even if they claimed that they stopped, they already broke our trust.

  2. Will it work with other mods?
    Depends what version you use. Vulkan verions in my Modpack could cause crashes or glitches, as it changes the API from OpenGL to an API not support by Minecraft, while with Sodium was made to give great performance and better compability because it keeps the API Minecraft uses which is OpenGL, by not including Vulkan.

  3. Will this break Multiplayer servers?
    No, neither Vulkan nor Sodium will break your multiplayer servers.

Vanilla Minecraft Concern Questions

  1. Will it kill the vanilla feeling?
    No, NanoFabric was made to make the vanilla Minecraft intact and will NOT remove the vanilla feel but instead, just performance to make it feel smoother.

  2. Will this change gameplay or add new features?
    No, like before this is just a performance modpack that will NOT ADD any new mechanics nor items in Minecraft, this was only made for you to enjoy the performance and game on vanilla Minecraft.

Other Possible Questions

  1. Do I need to configure anything?
    No, it was made to be ready out of the box, but you can change it in your needs for performance.

  2. Can I add/remove mods in the Modpack?
    Absolutely, you may add/remove any mods you want in NanoFabric, from what you want and need for your Minecraft worlds but if you remove/swap some performance mod it may decrease your FPS or stability.

Warning:

This is those stereotypical modpacks that gives "FPS Boost", this is my fault at that time as I didn't realize it was already a plague at that time. If you are not interested, please look other cool and better projects.

Frequently Asked Questions

NanoFabric 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 NanoFabric 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 NanoFabric without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.3). 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.

NanoFabric 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.
