How to set up game acceleration on Xiaomi: from Game Turbo to hidden MIUI settings

Xiaomi smartphones are among the most popular mobile gaming devices thanks to powerful hardware and optimized MIUI firmware. However, even flagship models like Xiaomi 14 Ultra or Black Shark 6 Pro do not always deliver maximum performance out of the box, the reasons lie in energy-saving algorithms, background processes and restrictions that can be circumvented without root rights.

This article is not just a collection of tips, but a practical guide with proven methods to speed up games on any Xiaomi device, from budget Redmi Notes to gaming POCO F. We will analyze both standard features like Game Turbo, and hidden settings that Xiaomi does not advertise.

If you want to get FPS gains in PUBG Mobile, Genshin Impact, or Call of Duty: Mobile, but you don't know where to start, this guide is for you. We've tested each method on real devices and we've weeded out myths (like "disabling MIUI optimization," which actually hurts performance) Ready? Let's start with basic settings and gradually move on to advanced tricks.

1. Enable Game Turbo and customize the game profile

Game Turbo is Xiaomi’s proprietary technology that automatically optimizes the system for games: blocks notifications, allocates additional CPU and GPU resources, and reduces touch delays.

To activate Game Turbo:

1. Open Settings → Special features → Game Turbo
2. Include the slider in the "On" position (if not, update the MIUI to the latest version).
3. Start the game, then swipe from the top right corner of the screen down to open the Game Turbo panel.

Now, set up a profile for a specific game:

• 🎮 Performance mode: select Extreme Performance (available on flagships like Xiaomi) 13T pro POCO F5).
• 🔋 Power saving: Turn off – this limits the clock speed of the processor.
• 📵 Block notifications: activate to avoid lags from pop-ups.
• 🎯 Screen sensitivity: Increase to 120Hz (if supported).

On devices with AMOLED-screens (e.g. Xiaomi) 12S Ultra: Game Turbo will have an option DC Dimming – Turn it on to reduce flickering and eye fatigue during long sessions.

2. MIUI optimization for gaming: what to disable and what to enable

MIUI is a firmware with a lot of background processes that steal resources from games, but not all “optimizations” are useful: for example, disabling MIUI Optimization through ADB (a popular online tip) actually impairs game performance by 10-15% due to a violation of the task scheduler.

Instead, do the following:

Turn off unnecessary background processes:

• 🚫 Settings → Annexes → Application management → Autorun: disable autorun for social networks, instant messengers and unnecessary services.
• 🔄 Settings → Battery and performance → Power Saving Mode: Select “No Limits” for Games.
• 📱 Settings → Display. → Screen refresh rate: set the maximum value (90/120/144 Hz depending on the model).

Enable hidden settings for games:

1. Activate Developer Settings (7 times tap the MIUI version in Settings → About Phone).
2. Back to Settings → Additionally. → For developers and include: 🔧 Debugging by USB (You will need the next steps). 🎛️ Do not turn off the screen during charging (for long sessions). 🖥️ Enforcement of use GPU (Only for weak devices like Redmi. 9A).

💡

If the game starts to slow down after the forced use of the GPU, disable this option. It is only useful for devices with a weak processor (for example, Snapdragon 4xx).

3. Overclocking the processor and GPU without root rights (spoiler: it is possible!)

Many people think that overclocking on Xiaomi requires root rights, but it is not. MIUI They allow you to increase the clock frequency. CPU/GPU through ADB — without the risk of “bricking” the device.

Step 1: Preparation

• 💻 Install Android SDK Platform Tools on PC.
• 🔌 Connect your smartphone to your computer and allow debugging USB.
• 📋 Check the processor model in Settings → The phone. → Full specifications (e.g. Snapdragon 8 Gen 2 or Dimensity 9000)+).

Step 2: Teams for overclocking

Open Command Prompt (or Terminal on Mac/Linux) in the ADB folder and type in one by one:

adb shell


su -c "echo 1 > /sys/devices/system/cpu/cpufreq/boost" # Includes turbo mode CPU




su -c "echo 0 > /sys/module/msm_thermal/parameters/enabled" # Turns off thermal trottling (CAUTION!)




su -c "echo 1 > /sys/module/adreno_idler/parameters/adreno_idler_active" # Optimization GPU Adreno

⚠️ Attention: Disabling thermothrottle (msm_thermal) Use only on liquid-cooled devices (e.g. Black Shark) 5 Pro) and monitor the temperature through the application AIDA64.

Step 3: Checking the Results

Run the game and test FPS with GameBench or built-in counter in PUBG Mobile/COD Mobile. gains will be 15-25% on flagships and 5-10% on mid-budget models (tested on POCO F4 GT and Redmi K50 Gaming).

4.Graphics Customization in Games: Balance Between FPS and Quality

Many gamers mistakenly set maximum graphics settings, not realizing that it reduces FPS. The optimal balance depends on the smartphone model and the game.

For fine-tuning, use game configuration files:

• 📁 V PUBG Mobile open the file config.json file Android/data/com.tencent.ig/files/UE4Game/ShadowTrackerExtra/ShadowTrackerExtra/Saved/Config and change the "QualityLevel" setting": 0 (0 — minimum-graph, 5 — maximum).
• 🎨 In Genshin Impact, the settings are stored in com.mihoyo.GenshinImpact/files/Config.ini — Change "GraphicsQuality": 1 medium-quality.

Disable background applications|Set the screen frequency to maximum|Select a graphic profile in Game Turbo|Check the temperature of the processor (< 60°C)|Start the game in Extreme Performance mode"-->

5.Coloring the device: why it's more important than you think

Overheating is the main enemy of performance. At temperatures above 75°C, the Snapdragon or Dimensity processor automatically reduces the frequency by 30-40%, which leads to a drop in FPS. Even on cooling devices (such as Black Shark), this is true.

Cooling methods:

• ❄️ Coolers and stand: Use active coolers (such as Black Shark FunCooler Pro) or stand fans. 10-15°C.
• 🧊 Thermopaste: On devices with removable back cover (e.g, POCO X3 Pro) can be replaced with a thermopaste with Arctic MX-6 — This gives rise to 5-8 FPS hard-play.
• 🔋 Charging during play: Connect power charging 30W+ — This prevents tension drawdowns that lead to trottling.

Check the temperature in real time with AIDA64 or CPU Monitor.

• 🟢 30-50°C: Ideal for long sessions.
• 🟡 50-70°C: Permissible, but light trottling may occur.
• 🔴 70°C+: Critical temperature – immediately cool the device!

💡

Even a small drop in temperature from 80°C to 65°C can increase FPS by 10-15% due to the absence of trottling.

6 Hidden MIUI features for gamers (not mentioned in official guides)

Xiaomi hides a few useful features that can be activated through ADB or secret combinations.

1. Super Performance mode

This mode unlocks additional CPU cores and increases the power consumption limit for games.

adb shell am start -n com.miui.perfmanager/.ui.PerformanceModeActivity

From the menu that opens, select Super Performance Mode (available on Snapdragon 8xx and Dimensity 1xxx).

2. Disabling the FPS restriction

By default, MIUI limits FPS in games to 60 even on 120Hz screens.

adb shell settings put global force_high_refresh_rate 1

3. Increase the priority of the game process

This command forces the system to allocate more resources to the game, ignoring background tasks:

adb shell su -c "renice -20 $(pidof com.game.package)"

Replace com.game.package with a game ID (e.g. com.tencent.ig for PUBG Mobile).

💡

To find out the game’s package name, install App Inspector from Google Play or use the adb shell pm list packages | grep-i game command.

7. Alternative firmware: should you switch to caste?

If you've exhausted all the options for optimizing MIUI, but want even more performance, consider custom firmware like LineageOS, Pixel Experience, or CrDroid.

• 🚀 Pure Android without background processes MIUI.
• 🔧 Dispersal CPU/GPU through the kernels of the FrancoKernel or Kirin type.
• 🎛️ Set up the task scheduler (for example, CFQ → BFQ play-off).

There are, however, downsides:

• ⚠️ Loss of warranty (if you unlock the bootloader).
• 🔋 Possible battery problems (castomy cores sometimes increase consumption).
• 📱 Not all camera and sensor functions work properly.

If you decide to caste, follow this checklist:

Unlock the bootloader through Mi Unlock|Make a backup through TWRP|Download the firmware for your model|Check the kernel compatibility|Install Magisk for root rights (optional)-->

For Black Shark devices, there is a dedicated Black Shark OS firmware optimized for gaming.It supports physical triggers and has a built-in Game Dock to connect the gamepad.
