WelnoX
The best optimization modpack in the newest minecraft versions! With the best performance mods, you can get a high FPS!
Quick answer
Which WelnoX release should I use?
v26.07.31-26.1.2-vulkan is a complete pack release for 26.1.2 with Fabric 0.19.3. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 42 mods in this pack file.
Pack setup
How should I set up WelnoX for players and a server?
Use v26.07.31-26.1.2-vulkan as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.
A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.
These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.
What are the server requirements for WelnoX?
v26.07.31-26.1.2-vulkan. Change the pack release and its contents or setup may change too.
The selected pack release is v26.07.31-26.1.2-vulkan. That file is for Minecraft 26.1.2 with Fabric 0.19.3. It contains 42 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

🚀 Sodium vs Vulkan Version
After testing both versions, I personally prefer the Vulkan version.
Why? Because on my system, I get nearly 2× more FPS compared to the standard Sodium build.
That said, performance may vary depending on your hardware.
📝 Note: This is a matter of personal preference — some users may experience better results with Sodium. It's worth trying both to see what works best for you.
