How to turn off the acceleration of games on Xiaomi Redmi Note 8 Pro: all ways

Xiaomi Redmi Note 8 Pro is one of the most popular smartphones for gamers thanks to the powerful MediaTek Helio G90T processor and Game Turbo technology. However, sometimes built-in game acceleration features can cause the opposite effect: overheating, slowing down or unstable frame rate. If you notice that the games on your device perform worse after MIUI updates or performance mode activation, perhaps the fault is automatic system optimizations.

In this article, we’ll look at how to completely disable the acceleration of games on the Redmi Note 8 Pro, including hidden MIUI settings, engineering menus, and even manual control of CPU clock speeds. You’ll learn what parameters affect performance, how to adjust them without risk to the device, and what to do if games start to work even worse after turning off the acceleration, and we’ll analyze when to turn off optimizations really is necessary and when to leave them on.

Why does the speeding up of games interfere?

The MIUI’s acceleration feature (including Game Turbo and Performance Mode) is designed to improve FPS and reduce delays.

• 🔥 Overheating of the processor due to forced acceleration of cores.
• 🐢 Trottling (automatic frequency reduction) with prolonged sessions.
• 🎮 Artifacts in graphics due to aggressive optimization GPU.
• 🔋 Accelerated battery discharge (up to 30% per hour of play).

This is especially true for the Redmi Note 8 Pro, where the MediaTek Helio G90T is prone to overheating under high loads.In some games (such as Genshin Impact or Call of Duty: Mobile), the system can artificially limit performance to avoid critical heating, which leads to jerks and FPS drops.

In addition, after the MIUI updates (especially on version 12.5+), the acceleration algorithms have become more aggressive, which sometimes conflicts with the settings of the games themselves. For example, PUBG Mobile can automatically lower the graphics settings even if you manually set Ultra HD + 60 FPS.

Method 1: Disable Game Turbo in MIUI settings

The easiest and safest method is to deactivate the built-in game accelerator through the standard menu, which does not require root rights and is suitable for most versions of MIUI.

1. Open the Settings. → Special facilities.
2. Go to Game Turbo (or Game Mode in older versions).
3. Turn off the Game Acceleration switch (could be called Performance Optimization).
4. In the additional settings (⚙️ In addition) deactivate: 🔄 Automatic memory cleansing (can close the background processes of games). 📊 Monitoring FPS (Sometimes it creates additional stress). 🎧 Sound optimization (may conflict with game settings).

Please note that in some firmware, Game Turbo can automatically turn on when you start games. To avoid this, also turn off automatic game recognition in the mode settings.

⚠️ Note: Some custom firmware (e.g. Xiaomi.EU) may not have a Game Turbo section. In this case, use Method 3 (engineering menu).

Method 2: Manual performance control through “Developer Mode”

If you can't disable Game Turbo, you can manually limit the background and optimize the processor, and you can activate the developer mode:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version until the notification “You became a developer!” appears.
3. Back to Settings → Additionally. → For developers.

In the developer section, find and disable the following parameters:

Important: If your version of MIUI does not have the option “CPU Frequency Fixing”, do not turn it on through the engineering menu (Method 3) without understanding the consequences – this can lead to overheating!

💡

If the game starts slower after the changes, try to return the Background Process Limit settings to the default value (standard limit).

Method 3: Engineering menu (for power users)

The engineering menu (#4636##) allows you to fine-tune network, CPU and graphics settings, but the wrong actions here can cause failures, so follow the instructions carefully.

1. Open the Phone app and enter the combination: ##4636##.
2. Select the phone information (or Battery information) section.
3. Scroll down to the "CPU Usage" block.
4. Click on Menu (three dots in the top right corner) and select CPU Settings.

On the menu that opens:

• 🔧 Disable Auto Hotplug (if available) – this will prevent automatic shutdown of the processor cores.
• 📉 Install «CPU Governor" in ondemand or conservative mode (instead of performance).
• 🔄 Turn off the Thermal Engine (if any) – this will reduce the aggressiveness of trottling.

Warning: Changes to the engineering menu are not saved after the reboot. To fix the settings, use applications like Kernel Adiutor (root rights required).

Method 4: Use ADB-commands without root)

If standard methods don’t work, you can disable optimizations via Android Debug Bridge (ADB), which doesn’t require root rights, but requires a computer.

Steps:

1. Download and install ADB Tools on PC.
2. Enable USB debugging on your phone (Settings → About Phone → MIUI Version → 7 taps → For developers → USB debugging).
3. Connect the Redmi Note 8 Pro to your PC and open the command line in the folder with ADB.
4. Enter the commands in turn: adb shell pm disable-user --user 0 com.miui.gameturbo pm disable-user --user 0 com.xiaomi.glgm

These commands completely disable Game Turbo and related services. To get it back, use:

pm enable com.miui.gameturbo


pm enable com.xiaomi.glgm

⚠️ Note: On some firmware, disabling com.xiaomi.glgm may cause errors in the graphics accelerator. If after completing commands, the games stopped running, return the settings back.

Method 5: Installation of a custom core (for advanced)

If you’re willing to take drastic measures, you can install a custom core (like Perseus or FrancoKernel) that offers flexible CPU and GPU configuration.

• 🔓 Unlocked bootloader (unlocked bootloader).
• 🛠️ Established TWRP (custom recovery).
• 📱 Backup of data (risk of loss of information).

Advantages of the custom core:

• ⚡ Manual control of clock frequencies CPU/GPU.
• 🌡️ Adjusting the trottling thresholds (prevents overheating).
• 🎛️ Optimizing the task scheduler for games.

Among the popular cores for the Redmi Note 8 Pro stand out:

Important: Installing a custom core will void the warranty and may cause the device to break. Before you run the firmware, check the feedback on forums (such as 4PDA or XDA) and make sure the kernel is compatible with your version of MIUI.

💡

Castomic kernel is the last resort. If you're not sure about your skills, use Methods 1-4.

What if the game gets worse after the acceleration is turned off?

In some cases, disabling MIUI optimizations can lead to lower FPS or higher lags, because the system stops managing resources in the background.

1. Return Game Turbo settings. Enable Performance Optimization back, but only turn off automatic memory clearing and FPS monitoring.
2. Use third-party boosters. Apps like the GFX Tool or Game Booster 4x Faster let you manually adjust the graphics and performance for each game.
3. Limit background processes. In Settings → Apps → Autorun, disable autoruns for unnecessary applications (especially social networks and instant messengers).
4. Reset your graphics settings in the game. Sometimes games save optimized MIUI settings. Try resetting your graphics to standard values in the game menu.

If nothing helps, it may not be the acceleration problem, but the thermal paste or battery wear. On the Redmi Note 8 Pro, the thermopaste dries after 2-3 years of use, causing it to overheat even under standard settings, in which case it will require a replacement of the thermopaste.
