How to speed up games on Xiaomi: from overclocking GPU pre-subtly MIUI

Xiaomi smartphones are among the most popular mobile gaming devices due to the price/performance ratio, but even flagship models like Xiaomi 14 Ultra or Black Shark 5 Pro eventually begin to slow down in modern games like Genshin Impact, PUBG Mobile or Call of Duty: Mobile.The reasons are diverse, from overheating of the processor to unoptimized background processes. MIUI.

In this article, we will discuss 10 Proven ways to speed up games on Xiaomi, including hidden developer settings, overclocking the graphics accelerator, cooling optimization, and even hardware tricks for models with Snapdragon 8 Gen 2 or Dimensity 9000+. All methods tested on current firmware MIUI 14/15 HyperOS and are compatible with most devices from budget Redmi 10C top-end POCO F6 Pro.

Important: Some methods require unlocking the bootloader or root rights — we've marked them with special warnings, starting with the safest ways (cleaning the cache, adjusting the graphics) and then moving on to "heavy artillery."

1. Activation of Game Turbo Mode and Hidden Settings MIUI

Xiaomi’s Game Turbo utility is the first tool to optimize games, which automatically blocks notifications, limits background processes, and even allows you to record the clock speed of the processor, but most users use only 30% of its capabilities.

To enable the advanced Game Turbo settings:

1. Open Settings → Special features → Game Turbo
2. Activate the switch and add the game to the list through the button +.
3. In the game menu, tap on the icon. ⚙️ → Additional settings.
4. Turn it on: 🔄 Optimization FPS (frame-rate) 📵 Blocking tactile recoil (saving charge) 🔋 Performance mode (priority for the game) 🎮 Display FPS (monitor)

For models on HyperOS (such as Xiaomi 14) the path is slightly different: Settings → Annexes → Game Turbo → Game settings. It also features the Adaptive Synchronization option, which dynamically adjusts screen resolution to save resources.

💡

If your game is not listed in Game Turbo, add it manually through Other Games. → Select a file APK. It works even for emulators like this. PPSSPP ordolphin.

2.Acceleration GPU through the engineering menu (without root)

Many do not know that on Xiaomi smartphones with Qualcomm processors (Snapdragon) 778G+, 8 Gen 1/2) You can manually increase the clock speed of the Adreno graphics accelerator through a hidden engineering menu. FPS on 10–25% in games, but increases the heat.

Instructions for MIUI 14/15:

1. Open the phone app and enter the combination: ##4636##
2. Go to the tab Information about the phone.
3. Tap 5-7 times on the item OpenGL version ES, until the menu comes out. GPU Renderer.
4. Choose Force. GPU Rendering and setting the Enabled value.
5. Go back and go to Settings. GPU (It can be called Adreno Config).
6. Increase the parameter. GPU Clock Speed at 10-15% of the standard value (for example, from 650 MHz to 720 MHz).

Hardware techniques

To replace the heat paste with POCO F4 GT or Redmi K50 Gaming will be required:

1. Remove the back cover (use suction cups and plastic shoulder blades).
2. Disconnect the battery line (required!).
3. Remove the old paste with alcohol and cotton swabs.
4. Apply the new paste with a thin layer (a drop the size of a rice grain).

System cleanup: cache, background processes and “garbage» MIUI

MIUI It is known for the fact that over time “clog” the system with unnecessary processes, especially on budget models like Redmi. 9A or POCO M4 Even after the game is closed, the background services of com.miui.daemon or com.xiaomi.gamecenter can consume up to 15% CPU.

Cleaning checklist:

For deep cleaning:

1. Install. SD Maid (requires root) and run the scan on: 🗑️ Residual files (residues after deleting games) 📁 Empty folders (remains after updates) 🔄 Systemic debris (logs and dumps) MIUI)

Mi Cloud Sync

Settings → Xiaomi account

ADB

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


adb shell pm disable-user --user 0 com.xiaomi.ab

HyperOS has a new feature called Smart Cleanup, which automatically closes the background processes when you start the game. → Battery and productivity → Game mode.

5. Customization of graphics in games: the balance between FPS quality

Many players mistakenly twist all the graphics settings to the maximum, not realizing that it reduces the speed of the game. FPS. For example, in Genshin Impact, switch from 60. FPS 30 FPS Ultra graphics gives a smoother picture than Medium by 60 FPS drawdown.

The best settings for popular games:

For Unreal Engine games 4/5 (For example, Fortnite or Diablo Immortal, add a line to the config file:

r.MobileContentScaleFactor=0.8

This will reduce the render resolution by 20%, but will increase the FPS 30-40%. The configuration file is usually on the path:

/Android/data/{name game package}/files/UE4Game/...

💡

On Xiaomi with 120Hz screens (for example, POCO F5 Pro) force 90 Hz or 120 Hz in the display settings – this reduces input lag by 10-15 ms.

6. Use of custom cores and firmware (for advanced)

If standard methods do not help, there is a custom core firmware or transition to AOSP-It's a firmware (like Pixel Experience or LineageOS:

• 🚀 No trottling (kernels like Kirisakura or Perseus disable restrictions) MIUI).
• 🔧 Extended control over GPU (Configure governors through Kernel Adiutor).
• 🗑️ Clean Android without Xiaomi background processes.

Instructions for installing a custom core on Xiaomi 11T Pro (Snapdragon 888):

1. Unlock the bootloader through the Mi Unlock Tool (you will have to wait 7 days).
2. Install. TWRP For your model (download on twrp.me).
3. Download the kernel (e.g. StableKernel for Snapdragon 888) with XDA.
4. Boot in. TWRP (Power + Vol Up and stitch ZIP-kernel.
5. Sweep through Magisk to save root.

⚠️ Attention: On Xiaomi 12S Ultra and newer with Snapdragon 8+ Gen 1 custom cores can break the camera because of the closed source Leica drivers. TWRP → Backup!

Critical information: On devices with HyperOS (for example, Xiaomi 14), the custom core firmware can block access to banking applications (Sberbank, Tinkoff) due to the SafetyNet trigger.

7 Hardware upgrades: what really helps?

If software is exhausted, iron modification is left, and not all upgrades are equally useful — some (for example, replacing the battery with a more capacious one) can even worsen performance due to weight gain and heat.

Effective upgrades:

• 🔋 Battery replacement: Old battery with capacity below 80% of nominal reduces performance by 15-20% (MIUI limit CPU Replacement cost: 1,500-4,000 ₽.
• 🪛 Installation SSD-On a model with a microSD connector (for example, Redmi Note 11 Pro)+) You can connect the Portable SSD through USB-C Reading speed will go from 100 MB/s (eMMC) to 500.+ MB/s (NVMe).
• 📶 Antenna booster: For online gaming (e.g, PUBG Apex Legends Mobile is a weak signal. 4G/5G Adds lag. Amplifiers like Xiaomi WiFi Repeater Pro (2 000 ₽) ping down 20–50 miss.

Useless upgrades (don’t waste money):

• ❌ Increase RAM via swap file (on Xiaomi it doesn’t work due to restrictions) MIUI).
• ❌ Replace the screen with 144 Hz (if the motherboard does not support high frequency).
• ❌ Installation of additional coolers without thermal paste (effect is minimal).

8.Alternative methods: from emulators to cloud gaming

If your Xiaomi still doesn’t pull on modern games, consider alternatives:

Cloud gaming:

• 🎮 Xiaomi Game Cloud (beta for HyperOS) - streaming games from Xiaomi servers. Requires stable Internet (50)+ Mbit/s).
• 🖥️ NVIDIA GeForce NOW Xbox Cloud Gaming – Supports Fortnite, Cyberpunk 2077 and more AAA-They even work for Redmi. 8A.

PC game emulators:

• 🖥️ Exagear (emulator) x86 for ARM) — It allows you to play old games like Half-Life 2 or GTA San Andreas on Xiaomi. Requires root.
• 🎮 Wine for Android – to run World of Warcraft or League of Legends (only on flagships with 8)+ GB RAM).

The "Easy Game" mode in MIUI:

Starting with MIUI 14, Game Turbo introduced the "Light Mode" mode, which:

• Reduces the resolution of the render by 2 times (for example, with 1080p before 540p).
• Disables all post-effects (fog, shadows, reflections).
• Fixing. FPS level 30 for stability.

Included in Game Turbo Settings → Optimization → Easy play mode, suitable for weak devices like Redmi 9C or POCO M3.

💡

Cloud Gaming is the Best Option for Snapdragon Devices 6xx Or Helio Gxx, even Redmi. 7A Cyberpunk 2077 will be pulled through GeForce NOW well-connected.
