Nefix Optimized
An OPTIMIZED mod pack that will increase PERFORMANCE and FPS even on the WEAKEST devices, as well as simplify and improve your gaming experience
Quick answer
Which Nefix Optimized release should I use?
Nefix Optimized is a complete pack release for 26.2 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. 38 mods in this pack file.
Pack setup
How should I set up Nefix Optimized for players and a server?
Use Nefix Optimized 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 Nefix Optimized?
Nefix Optimized. Change the pack release and its contents or setup may change too.
The selected pack release is Nefix Optimized. That file is for Minecraft 26.2 with Fabric 0.19.3. It contains 38 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.
About this project
What kind of pack is Nefix Optimized?

How does this mod pack work?
This mod pack works very simply. From my own experience, I’ve tested many popular mod packs for optimization, and in many of them I noticed a major problem: CONFLICTS BETWEEN CERTAIN MODS AND SODIUM
Such a conflict can lead to a significant drop in FPS, since the same options—such as those in the popular Sodium base mod and the More Culling mod—overlap and perform the same optimization functions, which can cause FPS to drop. but in my mod pack, I’ve checked all the technical aspects of the mods to ensure that each one performs its specific function without causing conflicts.
And to my surprise, it turned out to be very lightweight—even I wouldn’t have expected that, given that I was adding 20–30 mods for the same function.
Start of installation

Additions
In addition to all of the above, I’ve also saved my settings so you don’t have to spend a lot of time configuring them when you first launch the game.
So you don’t have to go through all the hassle of testing this modpack as if you were just starting your workday hoping to earn more, I’ve included the results of my independent tests of vanilla graphics, as well as a number of popular shaders, on a fairly underpowered device (full specifications are listed below the text with FPS metrics)
↓BELOW ARE THE RESULTS OF MY SIMPLE INDEPENDENT TESTS↓ 8 chunks
| Pure vanilla Minecraft | Minecraft with sodium | Minecraft with my modpack |
|---|---|---|
| 350-450FPS | 500-600FPS | 600-800+FPS |
↓Shader tests with my mod pack↓ 16 chunks
| Shader name | Graphics preset | FPS result |
|---|---|---|
| AstraLex Shader | High | 75 |
| Solas Shader | Ultra | 60 |
| Photon Shaders | Ultra | 90 |
| Bliss Shader | High | 110 |
| BSL Shader | Ultra | 105 |
| Complementary Reimagined | High | 100 |
| Complementary Unbound | High | 95 |
| Rethinking Voxels | Ultra | 50 |
| MakeUp Ultra Fast 9 | High | 145 |
| Fantasy Reimagined | High | 105 |
| Fantasy Unbound | High | 90 |
| E-LITE shaders 5 | Max | 140 |
| Nostalgia Shader | High | 80 |
| Spooklementary | High | 85 |
| Super Duper Vanilla | Ultra | 140 |
| Visual Vibrance | High | 155 |
| VTXS Shader | Ultra | 65 |
Don’t panic if you notice a big difference in FPS between the vanilla graphics and the shaders—this is because I’m testing this on my laptop. If you have a desktop PC, you’ll get much better performance with the shaders. Also, keep in mind that the graphics card in my laptop is much weaker than an RX 580
In addition to this text result of my tests, you can also go to the "gallery" section and see all the simple tests there
↓My device specifications↓
- CPU - Intel core i5 11400H
- GPU - Nvidia RTX 3050 mobile
- MEM - 16GB DDR4 3200mhz
- SSD - WDC PC SN540
- OS - Windows 11 pro
If your results don't match mine, then idk what could be weaker than the 3050 for laptops frr
All my tests are not a serious confirmation that your FPS will always be as stated in the test, since all my tests are quite simple with a favorable scenario
