How to Enable 90 FPS in PUBG/BGMI on Low-End Phones (2025 Guide)

Competitive mobile gaming has evolved rapidly, making high refresh rates a necessity rather than a luxury for serious players. In titles like PUBG and BGMI, the difference between 60 FPS and 90 FPS can be the deciding factor in a close-range firefight. While modern flagship devices support these frame rates natively, many budget and mid-range users find their hardware artificially capped by developers to ensure stability. However, by understanding the technical limitations of budget devices and employing specific software optimizations, it is possible to bypass these locks. This guide explores the proven methods to enable 90 FPS PUBG BGMI on low-end phones, balancing raw performance with device safety to provide the smoothest possible battle royale experience.

Understanding the 90 FPS Advantage in Mobile Gaming

When you play PUBG 90 FPS low end phone, you are essentially increasing the frequency at which your screen updates its image. In a game where milliseconds matter, having a higher frame rate reduces input lag and provides a significant advantage in tracking moving targets. For low-end users, the transition to a higher frame rate often requires more than just a simple settings toggle; it requires a deep dive into how the game engine interacts with your mobile hardware.

Technical Note: Even if you unlock 90 FPS PUBG mobile through software, your physical screen hardware must support a 90Hz or higher refresh rate to see the visual benefit. However, the internal 90 FPS processing can still reduce touch latency on 60Hz screens.

How to Enable 90 FPS PUBG BGMI Safely

The most common method involves modifying the game's internal configuration files or using third-party tools. While these methods are effective, users must prioritize safety to avoid account bans. The 90 FPS config BGMI method is popular because it doesn't modify the game's binary code, only its performance parameters. This approach is generally safer than using illegal "mod apks" which often contain malware or triggers for anti-cheat systems.

Method 1: Utilizing Professional GFX Tools

A GFX tool acts as a bridge between the user and the hidden settings of the Unreal Engine 4. To enable 90 FPS PUBG BGMI using this method, you need to select a tool that is compatible with the latest game version (3.5+). Look for tools that offer "Zero Lag Mode" and "Hardware Acceleration."

Resolution Control

Lowering resolution to 960x540 can drastically improve the stability of high frame rates on budget CPUs.

FPS Selection

Always select the 90 FPS option while keeping graphics at "Smooth" to prevent thermal throttling.

Method 2: Manual Config File Modification

For those who prefer a manual approach to unlock 90 FPS PUBG mobile, editing the 'Active.sav' file is the gold standard. This file resides in the game's data folder. By using a Hex Editor, players can change the FPS index value. This method is highly effective for BGMI lag fix 90 FPS because it forces the game engine to prioritize frame delivery over visual fidelity.

"Optimizing for 90 FPS on a budget device is about managing heat as much as it is about software tweaks. Without proper cooling, your phone will throttle performance within minutes." — Mobile Hardware Specialist

Hardware Optimization for Low-End Devices

Software tweaks can only take you so far. To maintain a consistent 90 FPS, you must ensure your hardware environment is optimized. This includes clearing system cache, disabling background synchronization, and managing device temperature. A BGMI lag fix 90 FPS strategy must include thermal management, as heat is the primary enemy of sustained mobile performance.

Warning: Overclocking your GPU on low-end phones can cause permanent hardware damage. Always stick to software-level FPS unlocking and use external cooling fans if possible.

Step-by-Step Guide for 90 FPS Config BGMI

1. Download a verified 90 FPS config BGMI file from a reputable gaming community.
2. Locate your game data folder: Android/data/com.pubg.imobile/files/UE4Game/ShadowTrackerExtra/Saved/SaveGames.
3. Backup your original Active.sav file to a safe location.
4. Replace the original file with the downloaded config or edit the values at offset 0x30 to '06' using a hex editor.
5. Restart your device and launch the game to see the "90 FPS" option in settings.

Optimizing System Settings for Better Performance

Beyond the game files, your Android OS settings play a crucial role. Enable "Developer Options" and toggle "Force 4x MSAA" off, and ensure "Disable Hardware Overlays" is turned on. These settings help the GPU focus entirely on rendering game frames. If you want to play PUBG 90 FPS low end phone, ensuring your RAM is not clogged by social media apps is vital.

Pro Tip: Use the built-in "Game Mode" or "Game Turbo" feature found on Xiaomi, Realme, and Samsung devices to prioritize network data and CPU cycles for the game.

Addressing Potential Risks and Account Safety

When you attempt to enable 90 FPS PUBG BGMI, the biggest concern is the 10-year ban. To stay safe, never modify the 'paks' folder. Only modify the 'Saved' folder. The anti-cheat system usually scans for modifications in the core game assets. Configuration changes in the user-saved directory are generally overlooked as they fall under preference settings rather than cheating.

Common Issues and Troubleshooting

If you find that the 90 FPS option disappears after a game update, you will likely need to re-apply the 90 FPS config BGMI. Game updates often reset the local configuration files to default values. Additionally, if you experience screen flickering, revert your resolution settings to the native device default.

Frequently Asked Questions

Can any phone run 90 FPS in PUBG/BGMI?

While software can unlock 90 FPS PUBG mobile, the processor must be powerful enough to push those frames. Generally, Snapdragon 600-series and above or MediaTek Helio G85 and above are required for a playable experience.

Is using a GFX tool for 90 FPS bannable?

Using third-party tools always carries a minor risk. To minimize this, use tools that do not require root access and only modify the basic configuration files without touching the main game data.

Will 90 FPS drain my battery faster?

Yes, increasing the frame rate requires more processing power, which leads to higher battery consumption and heat generation. It is recommended to play while the device is at a healthy charge level.

What is the best 90 FPS config BGMI version?

The best version is always the one that matches your specific game version (e.g., v3.5). Using an outdated config can cause the game to crash or fail to load textures.

Key Takeaways

• 90 FPS provides a significant reduction in input latency for competitive advantage.
• Safety is paramount; only modify files in the "Saved" directory to avoid bans.
• Thermal management is essential for maintaining high frame rates on budget hardware.
• GFX tools are the most user-friendly way to unlock 90 FPS PUBG mobile.
• Hardware refresh rate (Hz) determines if you can actually see the 90 FPS rendered.

Conclusion

Enabling 90 FPS on a low-end device is a transformative experience for any PUBG or BGMI enthusiast.
