# Lag or low FPS: what to do?

***

### 🧠 Step 1 – Close unnecessary programs

First, close all software you don’t use while you play:

* Browsers (Chrome, Firefox, etc.)
* Discord (if you don’t need voice)
* OBS, Spotify, Steam, etc.

> 💡 The fewer programs your PC has open, the easier Minecraft runs.

***

### ⚙️ Step 2 – Lower graphics settings

Open **Options → Video**, then change these settings:

| Setting                  | Recommendation |
| ------------------------ | -------------- |
| Render distance          | 6 to 10 chunks |
| Graphics                 | “Fast”         |
| Antialiasing (Smoothing) | Off            |
| Shadows                  | Off            |
| Particle settings        | Minimum        |
| Smooth lighting          | Off            |
| VSync                    | Off            |
| Clouds                   | Off            |

> 🧩 These settings have a huge impact on performance!

### 🧱 Step 3 – Install an optimization mod

For version **1.21.4**, the best mods are:

* [**Sodium**](https://modrinth.com/mod/sodium) → massively improves FPS
* [**Lithium**](https://modrinth.com/mod/lithium) → optimizes game calculations
* [**Iris**](https://modrinth.com/mod/iris) *(optional)* → allows using optimized shaders

> ⚠️ These mods require **Fabric Loader** (to install from [fabricmc.net](https://fabricmc.net/)).

### 🔋 Step 4 – Allocate more RAM to Minecraft

1. Open your **launcher**
2. Go to the **profile options**
3. Find the setting **Memory (RAM)**
4. Set between **3 and 6 GB** if your PC allows it

> 🚫 Don’t allocate all your RAM, leave at least 2 GB free for Windows.

***

### 🌐 Step 5 – Check your Internet connection

A good **ping** is essential to avoid lag:

* Avoid unstable Wi‑Fi → prefer an Ethernet cable
* Close downloads or background videos
* Restart your router if necessary

***

### 🧹 Step 6 – Other helpful tips

* Update **Java** to the latest version (17 or higher).
* Update your **graphics drivers**.
* Restart your PC regularly.
* If you use a **custom launcher**, make sure it’s up to date.

***
