Why is your Xiaomi “slowing down” in games, even though the iron is powerful?
Have you ever noticed that even on the flagship Xiaomi 13 Ultra or POCO F5 models, some games don’t run as smoothly as expected? Lags, FPS drawdowns, unstable frame rates may all be due not to a “weak” processor, but to software constraints. This is where Game Driver comes on the scene, a little-known but critical feature of MIUI that manages the allocation of system resources during gaming sessions.
Many users mistakenly believe that to improve performance in games, it is enough to turn on “gamer mode” in the settings or install an overclocking app. However, Game Driver works at a deeper level - it interacts directly with the Android kernel and GPU drivers (Adreno or Mali), optimizing their work for specific games. Without the right configuration of this feature, even the Snapdragon 8 Gen 3 will not reach 100% of its potential.
In this article, we will discuss:
- 🔍 What is Game Driver and how it differs from the standard game mode in the game MIUI.
- ⚙️ Where is this feature in settings (and why is it often hidden).
- 📊 How to check if your smartphone supports Game Driver and which version.
- 🎮 Step-by-step instructions for setting up for maximum FPS Genshin Impact, Call of Duty Mobile and other games.
- ⚠️ Risks and side effects: overheating, battery discharge and possible bugs.
Game Driver vs Game Turbo: What's the Difference?
Many people confuse Game Driver with the usual Game Turbo, the proprietary game mode from Xiaomi.
| Characteristics | Game Turbo (MIUI) | Game Driver |
|---|---|---|
| Level of work | Appendix (over-the-top) | Core driver (low-level) |
| What's optimized | Notifications, brightness, tactile response | GPU/CPU frequency, task scheduler, frame buffer |
| Impact on FPS | Indirect (reduces interface lags) | Direct (increases staff stability) |
| Availability | On all devices with MIUI | Only on flagships (Snapdragon 8xx, Dimensity 9000+) |
| Setting up | Through the Game Mode menu | By means of hidden parameters or ADB |
Game Turbo is an add-on on Android that blocks notifications, turns off autobrightness and adds virtual triggers. It's useful, but it doesn't touch the hardware. Game Driver works at the GPU driver level, changing:
- 🔄 Task Planner: Prioritizes gameplay over backgrounds.
- 🖥️ Frame buffer: reduces delays between rendering and screening.
- 🔥 Clock frequencies: accelerating GPU/CPU limitlessly TDP (overheating).
- 📶 Network Packages: Optimizes Ping in Online Games.
Important: Game Driver is automatically activated only for pre-installed games (such as PUBG Mobile or Honor of Kings).
How to check if your Xiaomi Game Driver is supported
Not all Xiaomi devices have this feature, here’s how to find out if you have it on your smartphone:
- Open the Settings. → About the phone and check out the CPU model.Game Driver is only available on chips: 🔹 Qualcomm Snapdragon 8xx (865, 870, 888, 8 Gen 1/2/3) 🔹 MediaTek Dimensity 9000/9200 🔹 Google Tensor (in some models for the Indian market)
Install the Device Info app HW and find the Kernel section → GPU Driver. If there's a line in there. mi_gpu_perf or game_driver — function maintained.
Try entering the command in the engineering menu:
##4636## → Battery Information → Check "Game Driver Status"If there is a field, your phone is compatible.
List of officially supported models (as of 2026):
- 📱 Xiaomi 12/12S/12T/13/13 Pro/13 Ultra/14
- 📱 POCO F4/F5/F6 Pro, POCO X6 Pro
- 📱 Redmi K50/K60 Pro, Redmi Note 12 Turbo
- 📱 Black Shark 5/5 Pro/6/6 Pro (special firmware)
Complete list of unofficially supported devices
Note: On devices with Snapdragon 6xx or Helio Gxx processors, attempting to activate Game Driver via ADB may result in:
- ⚠️ Permanent system rebuttals.
- ⚠️ Artifacts of graphics ("teared" textures).
- ⚠️ Update block MIUI.
Game Driver turn-based setup for maximum FPS
If your device supports the function, follow this instruction. Before you start, make a backup of data - incorrect settings can lead to a system reset.

Charge your phone to 50%+
Install ADB-computer-driver
Download Platform Tools from Google

Method 1: Hidden MIUI Menu (without ADB)
- Open the Phone app and type in ##6484## If the code didn't work, try ##4636## → Battery Information → Game Driver Settings.
- In the Game Driver menu, select: 🔘 Enable Game Driver – Enable Game Driver. 🔘 GPU Render Mode → Performance (for maximum performance) FPS). 🔘 CPU Governor → Performance or Ondemand (for balance). 🔘 Frame Rate Control → Unlocked (unlocks the restriction of personnel).
Save the settings and restart the phone.
Method 2: ADB (for experienced users)
If there is no hidden menu, use the ADB commands:
- Connect your phone to your PC, enable USB Debugging (Settings → About Phone → MIUI Version → 7 times press to unlock the developer options).
- Open the command line in the folder with Platform Tools and type: adb shell su setprop debug.gamedriver.enable 1 setprop debug.gpu.perf 1 setprop debug.cpu.perf 1
- To apply settings for a particular game (e.g. Genshin Impact): setprop debug.gamedriver.package com.mihoyo.GenshinImpact setprop debug.gpu.fps 120
Game Driver Alternatives: What to Do If There Is No Function
If your Xiaomi doesn’t support Game Driver, there are a few ways to improve gaming performance:
- GFX Tools: Apps like the GFX Tool for PUBG or Game Guardian allow you to manually set resolution, FPS and graphical settings. Risk: can lead to a ban in online games.
- Castom cores: firmware like Perseus Kernel or FrancoKernel are optimized for gaming. Require an unlocked bootloader.
- Cooling: Physical temperature reduction (such as Black Shark FunCooler Pro) can increase FPS by 5-10% by preventing trottling.
- MIUI Optimization: Turn off unnecessary background processes through Settings → Applications → Autostart and Battery → Performance Mode.
Comparison of alternatives:
| Method | FPS growth | Risks. | Difficulty |
|---|---|---|---|
| GFX Tools | 5-15% | Ban in games | Low. |
| Castomic nucleus | 10-25% | Brick, loss of warranty | Tall. |
| Cooling | 3-10% | No. | Medium |
| MIUI Optimization | 2-8% | No. | Low. |
