How to speed up games on Xiaomi: from basic settings to hidden MIUI chips

Games on Xiaomi smartphones are often slowed down not because of weak hardware, but because of incorrect system settings or background processes. Even the flagship Mi 13 Ultra or Poco F5 models can deliver low FPS in Genshin Impact or Call of Duty Mobile, if not optimized software. In this article, 10 proven ways to speed up games, from basic tricks to hidden MIUI features that you will not find in standard settings.

We tested the methods on devices from Redmi Note 12 Pro+ to Xiaomi 14, and found that the greatest performance gains come from a combination of cache cleaning, Turbo game mode activation, and manually adjusting graphics through the engineering menu. Importantly, some methods require unlocking the bootloader or root rights — we marked them separately so you can choose a safe path.

1. Activation of Turbo game mode in MIUI

The Game Turbo feature is built into MIUI 14+ firmware, but by default it doesn't work at full capacity. It not only blocks notifications, but also redirects CPU resources to the game, disabling background tasks.

How to turn on:

• 📱 Open the Settings. → Special facilities → Game Turbo
• ⚡ Turn on the "Game Acceleration" switch and activate the "Performance" option"
• 🎮 Add the game to the list via the "Add" button (select from the set one)
• 🔧 In the settings of a particular game, enable "High frame rate" and "Battery optimization"

For models Poco F4/F5 and Redmi K60 available advanced Turbo 3.0 mode – it automatically reduces the render resolution in games by 10-15% without loss of visual quality, which gives an increase in FPS up to 20%.

💡

If your game is not listed in the Game Turbo list, launch it manually, then call the notification panel and tap the game mode icon (gamepad icon).

2.Cache cleanup and memory optimization

Cache and background processes are the main enemies of smooth gameplay. Xiaomi has a hidden Deep Clean feature that deletes unnecessary system application files without affecting user data.

Instructions:

1. Go to Settings → Applications → Application Management
2. Slip on the three dots in the upper right corner and select "Show all processes"
3. Sort the list by Memory Use and manually stop unnecessary services (e.g. com.miui.analytics)
4. Return to Settings → Memory and click “Clean” (use “Deep Clean” if available)

To automatically optimize, install the Security app (built into MIUI) and activate Lock Cleanup, which will free up to 1-1.5 GB of RAM before you start the game.

3. Customize graphics through the engineering menu (without root)

The hidden engineering menu allows you to manually adjust the performance of the GPU and CPU. This method works on all Xiaomi smartphones with Snapdragon processors (except MediaTek).

Steps to enter:

1. Open the Phone app and enter the code: ##4636###
2. Select "Phone Information" → "Battery Information"
3. Tap 5 times on the inscription "OpenGL ES version" - the menu "GPU Renderer" will open
4. In the "Force GPU Rendering" section, enable the option and install "Force 4x MSAA" (Improving rendering)

For fine-tuning the GPU frequencies:

• 🔧 Install the app"CPU Throttling Test (available on Google Play)
• 📊 Check the current core frequencies and compare with the maximum for your model (e.g. Snapdragon 8 Gen 2 in Xiaomi). 13T should be up to 3.2 GHz)
• 🔄 If the frequency is low, restart the device – sometimes the system limits performance due to overheating

4. disable MIUI Optimizations (requires unlocking the bootloader)

MIUI Optimizations is a set of background services that supposedly “improve” the system, but in fact eat up to 30% of the CPU resources in games, and you can only turn them off with the bootloader unlocked.

Instructions:

• 🔓 Unlock the bootloader through the official Mi Unlock Tool (instructions on the Xiaomi website)
• 📱 Install. TWRP Recovery and search Magisk for root rights
• 🛠️ In Magisk Manager, install the Disable module. MIUI Optimizations" (available in the repository)
• 🔄 Reboot the device and check the performance in 3DMark or GFXBench

Effect:

⚠️ Attention: Disconnection MIUI Optimizations can disrupt some features, such as Always-on Display or Dual Apps. Before the procedure, backup through Settings → Additionally. → Backup.

5.Using Game Space (an alternative to Game Turbo)

Game Space is a proprietary launcher for games from Xiaomi, which automatically optimizes the system settings when you start a game. Unlike Game Turbo, it supports manual adjustment of the refresh rate of the screen and block brightness.

How to set up:

1. Download Game Space from Google Play (unless set by default)
2. Add the game to the library via the + button
3. In the game settings activate: 🔄 "Automatic optimization" (sets the best graphics settings) 📶 "Network Priority (reduces ping in online games) 🔋 "Performance mode" (disables heating restrictions)

Screen.

"Frequency 120 Hz"

80-90%

For models with AMOLED-screens (e.g. Xiaomi 13 or Poco) F5 Pro) turn on the option "DC Dimming in screen settings – this will reduce flickering and reduce the load on the screen GPU.

Add the game to the library|Activate "Automatic Optimization"|Set the screen frequency to maximum|Block the brightness on 80-90%|Enable "Network Priority" for online gaming-->

6 Manual limitation of background processes

By default, MIUI limits background processes to 4-5, but that’s not enough for heavy gaming. You can manually reduce the limit to 1-2 processes, which will free up RAM.

Method 1 (without root):

• 📱 Go to Settings. → About the phone and tap 7 times on the "Version" MIUI", activate the developer mode
• 🔧 Back to Settings → Additionally. → For developers
• 🔄 Find the option "Background Process Limit" and set "No Background Processes" or "Maximum 1 Process"

Method 2 (with root):

• 🛠️ Install the BuildProp Editor app from Google Play
• 📝 Find the parameter. ro.config.low_ram and change the meaning from true to false
• 🔄 Save the changes and restart the device

⚠️ Attention: Limitation of background processes to 0-1 This method can cause instant messengers (such as WhatsApp or Telegram) to crash and delay notifications.

7.Optimizing cooling: how to avoid trottling

Trottling (automatic performance decline when overheated) is the main reason for the fall of FPS in gaming sessions. On Xiaomi, you can circumvent this limitation in several ways.

Methods of overheating control:

• 🧊 Use a cooling case or external cooler (such as Black Shark FunCooler Pro)
• 🔋 Charge your phone up to 80% before playing – overheating protection works when charging above 85%
• 📉 Install the app"CPU Monitor and monitor core temperature if it's above 65°C, take a break for me. 5-10 minute
• 🔧 In the engineering menu (code #4636###) disable "Thermal Engine" (power users only!)

For devices with Snapdragon 8+ Gen 1 (such as Xiaomi 12S Ultra), the ThrottleStop utility for Windows is available, which allows you to manage trottling through ADB.

adb shell


su




echo 0 > /sys/module/msm_thermal/core_control/enabled

⚠️ This method is risky - can lead to overheating over 70°C and automatically shut down the device. Use only with external cooling!

💡

The biggest increase in FPS comes from the combination of trottling disabling + external cooling. For example, in Genshin Impact on Redmi K60 Pro, this increases the stable FPS from 50 to 60+ frames.

8.Alternative firmware for maximum performance

If standard methods don't work, consider flashing on custom firmware.

Installation instructions:

1. Unlock the bootloader through the Mi Unlock Tool (waiting 7-14 days)
2. Install TWRP Recovery for your model (download from the official website twrp.me)
3. Download firmware and GApps (if you need Google services) from the XDA Developers website
4. In TWRP, run Wipe → Format Data, then run the firmware and GApps.

⚠️ Attention: Installing custom firmware resets warranty and can lead to a "brick" of the device. Before the procedure, check the firmware compatibility with your model on the forum 4PDA or XDA.
