How to Remove Games Acceleration on Xiaomi: A Complete Guide for Gamers

Xiaomi smartphones have long proven to be great mobile gaming devices thanks to powerful hardware and optimized software. However, many users face the unpleasant problem of artificially accelerating games, when the game begins to “slow down” or “accelerate” for no apparent reason. This is due to the built-in Game Turbo feature, which tries to “optimize” performance, but often only spoils the gaming experience.

In this article, we’ll look at 5 proven ways to completely disable the acceleration of games on Xiaomi, Redmi and POCO, including hidden MIUI settings, changing configuration files, and even manually managing FPS. You’ll learn why this happens, how to check current settings and what to do if standard methods don’t help, and how to avoid typical errors that can lead to system failures.

Important: all instructions are relevant for MIUI 14/15 and models 2022-2026 (including Xiaomi 13/14, Redmi Note 12, POCO F5). If you have older firmware, some points may differ - check the version in Settings → About phone.

Why Games Are Accelerating on Xiaomi: The Main Reasons

The artificial acceleration (or, conversely, slowing down) of games on Xiaomi is not a bug, but a feature of the system, the manufacturer has built several mechanisms that automatically adjust the performance of games:

• 🔄 Game Turbo – a proprietary optimization mode that forcibly limits FPS It's a quick rendering, or it's a quick rendering, based on the game's "analysis," and it often doesn't work properly, especially in online shooters like this. PUBG Mobile or Call of Duty: Mobile.
• ⚡ Adaptive screen refresh rate – if the game does not support high FPS, The system can artificially "fit" the frames, which leads to jerks.
• 📉 Thermal trottling - when the processor overheats MIUI It automatically reduces performance, which causes lags, and in some cases, it manifests as an "acceleration" of animations.
• 🤖 Battery optimization – background processes limit resources for gaming, leading to unstable gaming FPS.

The most common problem is Game Turbo, which is enabled by default on all Xiaomi devices and actively interferes with the work of games, even if you did not start it. For example, in Genshin Impact or Honor of Kings, it can force graphics to be reduced or combat animations to speed up, which interferes with normal gameplay.

⚠️ Warning: If after the acceleration is turned off, the game starts to warm up or discharge the battery quickly, this means that the processor is running at full power without restrictions. FPS (below).

Method 1: Disable Game Turbo via MIUI settings

The easiest and safest method is to deactivate the Game Turbo in standard settings, which is suitable for most models and does not require superuser rights.

Instructions:

1. Open Settings → Applications → Application Management.
2. In the search box, enter Game Turbo (or Game mode on Russian firmware).
3. Click on the app, then select Disable (or Remove Updates if the Disable button is inactive).
4. Confirm the action and restart the phone.

If there is no option to disable, try an alternative path:

1. Go to Settings → Special Opportunities → System Acceleration.
2. Turn off the game optimization slider (or game boost).
3. Save the changes and check the game.

On some Xiaomi firmware (e.g. MIUI Global), the Game Turbo can be built into the Security App.

• Open Security → Acceleration → Game mode.
• Turn off all options related to game optimization.

Method 2: Manual FPS Limitation through Developer Options

If disabling Game Turbo didn’t help, the problem may lie in an unstable FPS, in which case manually adjusting the frame rate through the developer mode will help.

How to turn on Developer Options:

1. Go to Settings. → The phone.
2. Click on the MIUI version 7 times in a row (you will be notified “You became a developer”).
3. Return to the main settings menu and open Additional → for developers.

Now, let's set up FPS:

1. In Developer Options, look for FPS (or Window animation scale) restriction.
2. Set Off for Force GPU rendering (if you have an option).
3. Find Force 4x MSAA and disable it (this can cause lags in some games).
4. If there is a Force peak refresh rate, set it to Standard (or select a fixed value, such as 60 Hz).

For advanced users: if the game supports high FPS (for example, 120 Hz in Call of Duty: Mobile), but the system limits it, you can try to force the maximum refresh rate of the screen:

adb shell settings put global peak_refresh_rate 120

This command must be entered through ADB (for more information about ADB configuration, see the next section).

⚠️ Attention: Compulsory inclusion of high FPS If you don't play, you can overheat and discharge your battery faster.

💡

If after the changes in Developer Options, the games started to slow down, return all settings to the default state and try another way.

Method 3: Change configuration files (for advanced ones)

If standard methods fail, you can manually edit the system files that optimize games, which requires root rights or access through ADB.

Important: Incorrect editing of system files can cause malfunctions in the phone.

Instructions for ADB (without root):

1. Connect your phone to your PC and enable USB Debugging in Developer Options.
2. Open the command prompt (or Terminal on Mac/Linux) and type:

adb shell


su




mount -o rw,remount /system

1. Now edit the file. /system/etc/game_config.xml (or /vendor/etc/game_config.xml new-fixed):

adb pull /system/etc/game_config.xml

Open the downloaded file in any text editor and find lines with:

<game name="com.pubg.imobile">


<fps limit="60"/>




</game>

Delete or comment on (<!--- -->) all FPS restrictions, then save the file and download back:

adb push game_config.xml /system/etc/


adb shell chmod 644 /system/etc/game_config.xml




adb shell reboot

For root-enabled devices, you can use applications like Root Explorer or FX File Explorer to edit files:

• 📁 Move to the /system/etc/ or /vendor/etc/.
• 🔍 Find the files. game_config.xml, game_optimize.xml or perf_config.xml.
• ✏️ Edit or delete them (pre-made backup!).
• 🔄 Reboot the phone.

Method 4: Using third-party utilities to manage FPS

If you don’t want to dig into system files, you can use third-party applications to control FPS. They allow you to capture frame rates, disable MIUI optimizations, and even monitor the temperature of the processor.

Top.-3 Applications for controlling the acceleration of games:

Example of settings in Game Optimizer:

1. Install the application and provide all necessary permissions.
2. In the main menu, select Game Boost Settings.
3. Turn off the MIUI Game Turbo and Auto FPS Optimization options.
4. In Manual FPS Control, set the desired value (e.g. 60 FPS or Unlimited).
5. Add the game to the exclusion list if it is not automatically determined.

For Kernel Adiutor (with root only):

1. Go to the CPU section.
2. Turn off Thermal Throttling or set higher temperature thresholds.
3. In the GPU section, set a fixed frequency (e.g., 650 MHz for stable FPS).

⚠️ Note: Apps like Kernel Adiutor can cancel the warranty if the manufacturer detects traces of root access.

Method 5: Reset graphics settings via ADB (Universal Method)

If none of the above works, then there is “heavy artillery” – resetting all graphics settings through ADB. This method works on all Xiaomi devices regardless of the model and version of MIUI.

What you need:

• 🖥️ Computer with installed ADB and Fastboot.
• 📱 Included Debugging by USB phone-on.
• 🔌 Cable USB (preferably original).

Step-by-step:

1. Connect your phone to your PC and open the command line in the folder with ADB.
2. Enter a command to check the connection:

adb devices

If the device is displayed, continue:

1. Reset all MIUI optimizations for games:

adb shell settings put global hidden_api_policy 1


adb shell pm disable-user --user 0 com.miui.gameturbo




adb shell pm clear com.miui.gameturbo

1. Reboot the phone:

adb reboot

After the reboot, all Game Turbo settings will be reset and forced optimizations disabled. If you want to return everything back, use:

adb shell pm enable com.miui.gameturbo

This method is the only way to completely remove Game Turbo traces on MIUI 14+ firmware without root permissions, but once the system is updated, the settings may reset and the procedure will have to be repeated.

What do you do if nothing helps?

If you’ve tried all the ways, but the games are still speeding up or slowing down, the problem may be deeper:

• 🔥 Overheating of the processor – check the temperature through AIDA64 or CPU Monitor, if it's over 60°C, use a cooling stand.
• 🔋 Battery wear - if the battery is discharged too quickly, the system may artificially limit performance.Check battery health in Settings → Battery → Battery status.
• 🛠️ Firmware problems – if you have custom firmware (like LineageOS or Pixel Experience), some optimizations MIUI They may not work properly. Try to reflash the device to the official one. MIUI.
• 🎮 Game limitations – some games (like Free Fire) have built-in limits FPS In this case, only a modified version will help. APK (But it violates the rules of services like Google Play).

If you suspect that the problem is iron, try:

1. Test the phone on benchmarks (3DMark, Geekbench) – if the results are well below average for your model, there may be hardware malfunctions.
2. Reset your phone to factory settings (Settings → Additional → Recovery and Reset).
3. Contact the Xiaomi Service Center if the warranty is still valid.

💡

If games are only accelerated in certain scenes (like shooting PUBG), the problem is most likely to be optimizing the specific game: try changing the graphical settings inside the game itself or use modified configs.
