## What Are Fabulously Optimized and Simply Optimized?

Both Fabulously Optimized (FO) and Simply Optimized (SO) are Fabric-based modpacks designed to improve Minecraft’s performance without drifting far from the vanilla experience. They achieve this by bundling optimization mods like Sodium, Lithium, and Phosphor, but they differ in philosophy.

Fabulously Optimized aims to be a “plug-and-play” enhancement—it includes a curated set of quality-of-life mods (such as a minimap, zoom, and better crafting UIs) alongside performance boosts. Simply Optimized, in contrast, strips down to the bare essentials, focusing solely on FPS gains and stability. Both are lightweight enough to run on modest hardware, but SO typically edges ahead in raw frame rates due to fewer background features.

## Performance Comparison

Performance is the primary reason players seek out these packs. While exact FPS numbers depend on your hardware and settings, general observations show:

- **Fabulously Optimized** provides a significant boost over vanilla (often 2-3x on mid-range hardware) while keeping the game feeling complete. Additional mods like a dynamic light or first-person model will slightly lower FPS compared to a stripped-down pack.
- **Simply Optimized** sacrifices most non-essential features to maximize frames. It often runs 5-10% faster than FO on the same system because it only loads optimization modules and removes unnecessary code.

For players who need every last frame—such as PvP enthusiasts or those on very old PCs—Simply Optimized is the better choice. For everyday survival, FO’s extra polish may outweigh the small performance hit.

## Feature Set and Customization

Here’s a quick breakdown of what each pack includes out of the box:

| Feature | Fabulously Optimized | Simply Optimized |
|---------|----------------------|------------------|
| Performance mods (Sodium, Lithium, etc.) | ✅ | ✅ |
| Minimap / Waypoints | ✅ (Xaero’s Minimap) | ❌ |
| Zoom (Logical Zoom) | ✅ | ❌ (addable) |
| Better crafting (Roughly Enough Items) | ✅ (REI) | ❌ (addable) |
| Dynamic lighting (LambDynamicLights) | ✅ | ❌ |
| Lightweight texture fixes | ✅ (default) | ✅ (default) |
| Server compatibility | Full (vanilla) | Full (vanilla) |
| Mod loader | Fabric / Quilt | Fabric / Quilt |

Both packs allow you to add or remove mods manually, but FO comes pre-loaded with a “complete” vanilla+ experience, while SO gives you a clean slate to build upon.

## Ease of Installation and Updates

Both packs are available on Modrinth and CurseForge. Installation is straightforward via these launchers:

- **Fabulously Optimized** maintains an official CurseForge page and a separate Modrinth entry with regular updates for each Minecraft version.
- **Simply Optimized** is also updated frequently, but its smaller mod list means fewer update conflicts.

## Alternatives Worth Considering

If neither pack feels like the right fit, several other lightweight modpacks compete in this space:

- **Optimise+**: As described on Modrinth, “A Modpack designed to get the most juice out of your pc with the addition of not too many mods like other FPS modpacks out there.” It sits between FO and SO in terms of features.
- **Optimizium**: Another minimal pack aimed at low-end systems, often compared to SO but with a slightly different mod selection.
- **Faster Default**: Keeps all vanilla features intact while boosting performance, useful for players who dislike any changes.
- **Muoh Optimize X Vulkan**: Claims extreme FPS numbers (2500+) using Vulkan renderer, but requires compatible hardware.

## How to Decide: Fabulously Optimized vs Simply Optimized

- **Choose Fabulously Optimized** if you want a ready-to-play vanilla+ experience with minimap, zoom, recipe book, and other convenience mods without sacrificing too much performance. It’s ideal for survival players and builders.
- **Choose Simply Optimized** if your main goal is maximum frame rates on a low-end PC or for competitive PvP, and you don’t mind adding your own QoL mods later.
- **Consider alternatives** like Optimise+ if you want a middle ground or have specific hardware requirements.

Both packs respect vanilla gameplay and do not alter core mechanics, so you can play on any vanilla server without issues.
