If you enjoy playing PUBG Mobile or BGMI, you know how important smooth gameplay is. Imagine you’re in the final moments of a match, only a few opponents left, and suddenly your screen lags or the frame rate drops—you lose the fight in seconds. That can be really frustrating.
Many players want to know how they can make their game run better. In this guide, we’ll explain it in simple words: what affects performance, how you can improve it with safe methods, and what you should avoid to keep your account secure. By the end, you’ll have a clear idea of how to enjoy smoother, more stable matches without unnecessary risks.
What is a Config File in PUBG & BGMI?
A config file (short for configuration file) is a small file that stores custom game settings. Instead of using only the options shown inside the game, this file can adjust how the game looks and feels on your device.
Think of it like adjusting your TV picture settings. The TV comes with presets, but you can fine-tune brightness, contrast, or sharpness to suit your preference. In the same way, a config file lets you fine-tune PUBG or BGMI.
How it Works in the Game
When you launch PUBG or BGMI, the game reads different files to know how to run—this includes graphics, frame rates, textures, shadows, and more. A config file is just another way of telling the game, “Use these settings instead.”
Default Settings vs. Config File
The default settings are safe and work for everyone, but they can feel limited. For example, some phones may only show “High” graphics even if the device could handle more. A config file helps unlock more options, similar to revealing extra settings that aren’t normally visible.
Benefits of Using Config File
Better Graphics Performance
With the right config, you can boost your graphics to enjoy sharper visuals, richer colors, and more immersive gameplay.
Smooth Gameplay Experience
No one likes choppy frames when firing at enemies. Configs can unlock higher FPS like 60 or 90, making everything smoother and more responsive.
Unlocking Hidden Settings
Some configs let you enable Ultra HD or Extreme FPS that aren’t normally available on certain devices.
Saving Battery and Reducing Heating
Not every config is about high-end graphics. Some are designed for low-end phones, lowering textures and shadows to make the game run lighter. That means less heat, less battery drain, and more playtime.
Things You Need Before Applying Config File
Before jumping in, make sure you’re ready. Here’s what you need:
File Manager App
A good file manager is essential. It helps you access game folders and copy/paste files easily. Examples: ZArchiver, ES File Explorer.
PUBG or BGMI Updated Version (4.0)
Always check you’re on the latest version. Configs are version-specific, so using an old one might cause crashes.
Stable Internet Connection
You’ll need it for downloading the config file safely from trusted sources.
Backup of Original Files
Always keep a backup of your original game files. If something goes wrong, you can restore and play normally.
Step-by-Step Guide to Apply Config File in PUBG & BGMI 4.0
Alright, here’s the part you’ve been waiting for—the actual steps.
Step 1 – Download the Config File
Get the correct file for your version (PUBG or BGMI 4.0). Save it on your device.
Step 2 – Locate Game Folder
Open your file manager and navigate to:Android > Data > com.tencent.ig (for PUBG)
orAndroid > Data > com.pubg.imobile (for BGMI)
Step 3 – Copy and Paste the Config File
Inside the game folder, look for the “Files” or “UE4Game” folder. Paste the config file here, replacing the existing one if required.
Step 4 – Apply Permissions if Needed
Some configs may require you to set read/write permissions. Just ensure the file isn’t blocked by your device.
Step 5 – Restart the Game
Close the game if it’s running. Restart it, and your new settings should be active.
How to Check if Config File is Working
Signs That Config is Applied
- New graphics options available
- Game feels smoother than before
- FPS counter shows improvement
Checking FPS and Graphics
Turn on “Show FPS” in developer options or use in-game testing to confirm.
Cross-check with Default Settings
Compare before and after—if you see options like 90 FPS or HDR unlocked, it worked.
Alternatives to Config Files
GFX Tools
These apps let you adjust graphics without messing with files. They’re easier but may not unlock everything.
In-Game Settings Optimization
Simple but effective—adjust graphics, sensitivity, and controls inside the game itself.
Device-Level Optimization
Clear cache, close background apps, and use a gaming mode to boost performance.
Final Thoughts
Using a config file can make your PUBG or BGMI gameplay smoother and more enjoyable. It can help improve FPS, graphics, and overall performance, especially on devices with limited power.
Always be careful—only use safe and trusted sources, and keep a backup of your original files. Avoid anything that could give unfair advantages, because these games are meant to be enjoyed with skill and strategy.
If you want better performance with the 4.0 version, a good config file can make your gaming experience more fun and seamless.
