How to Unlock 90 FPS and 120 FPS in Mobile Games: Ultimate Smooth Performance Guide
Introduction: If you are playing competitive battle royale games like PUBG Mobile, Free Fire, or Call of Duty: Mobile, screen responsiveness is everything. Running your game at standard 30 FPS or 60 FPS is fine for casual play, but if you want to spot enemies faster, reduce recoil control latency, and experience butter-smooth animations, you need to unlock 90 FPS or 120 FPS.
Many modern smartphones come with high refresh rate screens (90Hz, 120Hz, or even 144Hz), yet the games often limit the graphics settings to "Ultra" or "Extreme" (60 FPS). This happens due to official device optimization white-lists or battery conservation safety metrics. In this comprehensive guide, we will show you exactly how to break these limits and unlock maximum frame rates safely on your device.
1. Match Your Phone's Refresh Rate with Game Settings
The most common mistake gamers make is trying to run a game at 90 FPS while their phone's display settings are still locked at a standard 60Hz. If your screen refresh rate doesn't match your game's engine output, your device will discard the extra frames, causing micro-stutters.
How to fix it: Open your phone's Settings > Display > Refresh Rate (sometimes called Smooth Display).
Switch the setting from "Standard / 60Hz" to Maximum / 120Hz or "Dynamic". If your screen refresh rate is not set to high manually, your device hardware will block the game from rendering higher frame counts altogether.
2. Configure Graphics Tools Safely (GFX Tools)
For low-end or mid-range devices that don't natively show the "90 FPS" option in the game graphics panel, external optimization configuration files or trusted customizer tools can help unlock the hidden potential of the game engine.
The Safe Method: Download a highly-rated, updated GFX optimization tool from the official app store. Select your specific game version (Global, BGMI, or Free Fire).
Change the resolution to match your screen resolution, set the graphics quality to Smooth, and manually select 90 FPS or 120 FPS from the frame rate dropdown menu.
Pro Tip: Always keep the graphics style on "Classic" or "Colorful" and disable heavy shadows. This prevents the phone's GPU from overheating while rendering higher frame rates.
3. Clear Device Overheating and Thermal Throttling
Even if you manage to unlock 90 FPS initially, your phone might drop back down to 40 FPS or 60 FPS after just 10 minutes of intense combat. This drop is called thermal throttling. When the internal processor temperature crosses a safety threshold, the system automatically cuts down performance to cool the device.
The Action Plan: Never play graphic-intensive games while charging your phone, as charging generates massive secondary heat.
Remove thick protective plastic or rubber cases before launching the game to let the phone radiate heat efficiently. If you are serious about competitive gaming, investing in a small clip-on smartphone cooling fan can maintain stable frame rates for hours without drops.
4. Enable Developer Options Focus Settings
Android devices have hidden configurations meant for developers that can boost heavy 3D application performance by forcing the hardware to utilize all available graphic processing rendering cores.
The Tweak: Go to Settings > About Phone and tap on the Build Number seven times until it says "You are now a developer".
Go back to system settings, open Developer Options, and scroll down until you find Force 4x MSAA or Disable HW Overlays. Turning these options on forces your smartphone to run graphic components directly through the primary GPU, ensuring stable, high-tier frame deliveries during hectic gameplay close-fights.
