# How Can I Improve Game Speed in AutoTrans?

This guide explains why AutoTrans can cause lag and how to improve performance during gameplay.

## Why does the game slow down and lag?

AutoTrans translates text in real-time as it appears on screen. The game must wait for each translation to complete before continuing. This causes lag or freezing, especially when:

* There is a lot of text on screen at once
* Menus or choice screens have many options
* The translation service response is slow
* The more text on screen = The longer the game waits = More lag

## Solutions to Improve Performance

#### **1. Use Translation Filters (Recommended)**

Prevent certain text from being translated to reduce processing time.

Go to [Translation Filters](/user-guide/autotrans/translation-settings.md) Settings and adjust Translation Filters to:

* Skip translating UI elements
* Translate only dialogue text

#### 2. Choose Faster Translation Services

Different translation services have different response speeds.

**Speed comparison (fastest to slowest):**

* **Google Lite** - Fastest option
* **Google Web** - Fast and reliable
* **DeepL API** - Fast with API key
* **DeepL Web** - Slower but higher quality

{% hint style="info" %}
**Recommendation:** Use Google Lite for games with heavy text. Switch to DeepL only if translation quality is more important than speed.
{% endhint %}

#### 3. Enable Translation Cache

Translation cache stores previous translations, so repeated text doesn't need to be translated again.

**Status:**

* Available from version **0.8.7**
* Enabled by default since **v0.8.9-beta**

#### 4. Reuse Translation Memory

If the game has been played before or has multiple versions, import the translation memory to avoid re-translating the same text.

**How to use:**

* **Export:** After playing, export the translation memory from AutoTrans
* **Save:** Keep the translation file for future use
* **Import:** When playing again or playing a similar version, import the translation memory

#### 5. Use Extract & Translate (Best for Performance)

For the smoothest experience, use Extract & Translate instead of real-time translation.\
Extract & Translate pre-translates all game text before playing, reducing lag during gameplay.
