To increase your game FPS and overall performance in PUBG Mobile, you can try tweaking the configuration file. Here are some general tips to improve performance:
1. Open the config file in a text editor (e.g., Notepad).
2. Look for settings related to graphics quality, resolution, and effects.
3. Lower the graphics quality to the lowest settings for better performance.
4. Reduce the resolution to a lower value to improve FPS.
5. Disable unnecessary effects like shadows, reflections, and anti-aliasing.
6. Adjust the frame rate settings to prioritize performance over visual quality.
7. Save the changes and restart the game to apply the new settings.
Please note that modifying the config file can affect the visual quality of the game, so it's essential to find a balance between performance and graphics. Experiment with different settings to see what works best for your device.
