How to increase FPS in games on Xiaomi: from MIUI settings to hidden chips

Xiaomi, Redmi and POCO have long been popular with gamers with powerful hardware at an affordable price. But even flagship models like the Xiaomi 14 Ultra or POCO F6 Pro sometimes give off unstable FPS in games — especially in heavy projects like Genshin Impact, Call of Duty Mobile or PUBG New State.

In this article, we’ll look at 10 proven ways to boost FPS on any Xiaomi device, from the budget Redmi Note 12 to the top-end Black Shark 6 Pro. All methods work without root rights and do not violate warranty. Importantly, some tricks require accuracy, because they affect hidden MIUI or HyperOS settings. If you’re a beginner, start with the simplest steps and gradually move to advanced ones.

Before you start optimizing, check the current FPS in the game. Use the built-in frame counter (if any) or third-party utilities like GameBench or FPS Meter. Write down the before and after scores so you can see the difference. Also pay attention to thermotrottling: if the smartphone overheats, the FPS will sag regardless of the settings, in which case you first solve the cooling problem (which we will also discuss below).

1. Enable performance mode in MIUI Game Turbo

MIUI Game Turbo (or HyperOS Game Center in the new firmware) is a built-in game accelerator from Xiaomi that optimizes system resources for games. By default, it works in a balanced mode, but it can be switched to maximum performance.

How to activate:

• 🎮 Open the Settings. → Special facilities → Game Turbo (or Settings) → Annexes → Game Center in HyperOS).
• 🔧 Select the game from the list (or add it manually).
• ⚡ Switch to Performance or Extreme Performance (on some models).
• 📊 Enable the “Improving” option FPS» and "Picture Optimization" (if any).

On HyperOS devices (such as Xiaomi 14 or Redmi K70), the path may be different: Settings → Display → Game Center. This menu also allows you to turn off notifications and background processes while playing, which will give an additional +5-10 FPS.

⚠️ Warning: Extreme Performance mode increases the load on the processor and battery. Use it only when connected to charging, otherwise the battery will go down 2-3 times faster.

2. disable MIUI Optimization (hidden setting)

One of the most effective but little-known features is disabling MIUI Optimization, which is responsible for “improving” the interface, but in practice often limits performance in games, especially on devices with Snapdragon 8 Gen 1/2. After it is turned off, FPS can grow by 15-25% (tests on POCO F5 and Redmi K60 Pro showed an increase from 45 to 58 FPS in Genshin Impact on medium settings).

How to turn it off:

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find the option “Disable MIUI Optimization” (or MIUI Optimization in English firmware) and deactivate it.
4. Reset the device.

After that, the game can run longer for 2-3 seconds, but stability is not limited. FPS It will improve significantly on some models (e.g. Xiaomi). 12T) This option is hidden - then you will have to use it. ADB-team:

adb shell settings put global miui_optimization_disabled 1

⚠️ Note: HyperOS devices (e.g. Xiaomi 14) may not have this option. Don't try to change system files manually, it will cause firmware to crash.

3.Tune the resolution and frequency of the screen refresh

Many users are unaware that screen resolution and refresh rate directly affect FPS. For example, in Call of Duty Mobile at 1920×1080 and 120Hz, the FPS will be lower than at 1600×720 and 60Hz. The optimal balance depends on the smartphone model and the game.

Recommendations for settings:

How to change the settings:

• 📱 B Settings → The display set a minimum refresh rate (e.g. 60 Hz instead of 120 Hz).
• 🎮 In the game settings, select the resolution below (but not below). 1280×720, Otherwise, the picture will be too blurry).
• 🔄 Enable adaptive frequency if supported (e.g. on Xiaomi 14C) LTPO-display).

💡

On devices with AMOLED-Include a dark theme in the game with screens (for example, Xiaomi 13 Ultra) – this will reduce the load on the game. GPU And add 2-5. FPS.

4. Clear background processes and cache

Background apps and cache can steal up to 30% of CPU resources, which is critical for heavy gaming, especially on devices with 6-8 GB of RAM (for example, Redmi Note 11 Pro+ or POCO X5 Pro), and regular cleaning gives an increase in FPS by 10-15 frames.

What needs to be done:

• 🧹 Clear the game's cache: Settings → Annexes → [Game] → Warehouse → Clear the cache.
• 🚫 Turn off autoloading of unnecessary apps: Settings → Annexes → Autoboot.
• 🔄 Use the built-in Optimizer (Security) → Optimization) to clean RAM before playing.
• 📦 Remove unused apps (especially heavy ones like Facebook or TikTok).

For deep cleaning can be used ADB-commands (connection to the PC is required):

adb shell pm trim-caches -1


adb shell cmd activity clear-top

⚠️ Note: Do not clear the cache of system applications (e.g. com.miui.home) – this may cause interface failures.

💡

Clearing the cache before each game session gives a steady boost to FPS, but don’t get carried away – frequent cleaning can slow down the launch of applications.

5. Use Game Space (for POCO and Black Shark devices)

The POCO and Black Shark lineups have a unique Game Space feature, similar to Game Turbo, but with advanced settings for gamers, where you can not only optimize FPS, but also adjust tactile returns, backlighting and even limit notifications from specific applications.

How to set up Game Space:

1. Open Game Space (the icon on the desktop or in the app menu).
2. Add the game to the list (click + in the upper right corner).
3. Select the “Performance” or “Extreme” profile.
4. Activate options: 🔋 «Ignore battery restriction (for maximum power). 📵 «Block notifications (so that nothing is distracting). 🎯 «Sensor optimization” (reduces delays when touching).

The Black Shark 5/6 Pro has additional features:

• 🖥️ «Magical Display – Improves color reproduction in games.
• 🎮 «Shark Space – a separate game mode with button customization.
• ❄️ «Liquid cooling" - forced start of the fan (if any).

6. Optimize the graphics settings in games

Many games (such as PUBG Mobile, Free Fire, or Honor of Kings) have hidden graphics settings that can be tweaked to boost FPS. Often these options are hidden in configuration files or accessed through ADB.

General recommendations for setting up the graphics:

• 🌿 Set the Grass and Shadows to a minimum (this eats up the most resources).
• 🔮 Turn off the “Particle Effects” and “Motion Blurr».
• 🖼️ Use Balanced or Performance Preset (not «HDR» or "Ultra»).
• 📱 Turn on Adaptive Graphics (if any) – the game will automatically reduce the load when overheating.

For advanced users: some games (such as Genshin Impact) allow you to edit config files. Game\GenshinImpact_Data\StreamingAssets\Config\GraphicsSettings.json You can manually change the settings of ShadowQuality or AntiAliasing, but be careful, the wrong values can lead to the ruin of the game.

Example of a command for PUBG Mobile (sets maximum FPS):

adb shell setprop debug.hwui.render_dirty_regions false


adb shell setprop debug.egl.hw 1

7. Overheating problems? Cooling solutions

Overheating is the main enemy of high FPS. At temperatures above 45°C, the processor begins to trott (reduce the frequency), which leads to frame drawdowns. On the Snapdragon 8 Gen 1/2, this is especially critical - the chip can lose up to 40% of performance when overheated.

How to deal with heat:

• ❄️ Use a cooling case or external cooler (such as Black Shark FunCooler Pro).
• 🧊 Apply the heat paste (relevant to older models like this) POCO F1 or Redmi K20 Pro).
• 🔋 Play with less than 80% charge – the full battery warms up more.
• 🌡️ Install the app CPU Monitor or Cool Tool for Temperature Control.

On HyperOS devices (such as Xiaomi 14), there is a built-in Smart Cooling feature to activate it:

1. Go to Settings → Battery and Performance → Thermal Management.
2. Select the “Performance” or “Game” mode.
3. Enable the option of Active Cooling (if available).

⚠️ Warning: Do not use artisanal cooling methods such as refrigerator or ice, which can cause condensation and short circuits.

8. Update the firmware and GPU drivers

Often low FPS is associated with outdated GPU drivers. Xiaomi regularly releases updates for Adreno (in Snapdragon chips) and Mali (in MediaTek), which optimize the experience in games.

How to update drivers:

• 🔄 Check system updates: Settings → The phone. → Update MIUI.
• 📦 Install the latest Adreno drivers via Google Play Services (update automatically).
• 🔧 For MediaTek download GPU Driver Update from MIUI App Store.
• 🛠️ If FPS drops after the update – roll back to the previous firmware version (via Fastboot or Recovery).

On some models (such as the Redmi Note 12 Pro+ with the MediaTek Dimensity 1080), it helps to manually install custom drivers via Magisk. However, this requires an unlocked bootloader and can lead to a loss of warranty.

List of the latest driver versions for popular chips:

💡

Updating GPU drivers gives the greatest increase in FPS on new chips (for example, Snapdragon 8 Gen 3). On older processors (for example, Snapdragon 732G), the effect is minimal.
