The world of Teyvat is incredibly beautiful, but it is this beauty that becomes the main enemy for owners of mid-range and budget smartphones. Genshin Impact is one of the most demanding mobile games on the market, and even last year’s flagships sometimes cannot provide stable 60 frames per second without overheating. If you experience freezes, a drop in FPS, or strong body heating while exploring locations like Fontaine or Natlan, it means that the system does not have enough resources to render complex graphics in real time.
There are many myths that the only solution is to buy a new device with a top processor Snapdragon 8 Gen 3 or Dimensity 9300. In fact, competent software optimization can work wonders. The right combination of in-game settings, Android system parameters and third-party utilities can increase the smoothness of gameplay by 30-40% even on older devices. In this material, we will analyze the technical aspects of the game engine and give specific instructions on how to “survive” in low frame rates.
Before taking radical measures like resetting settings or installing custom kernels, it is necessary to eliminate trivial configuration errors. Often, users set the maximum rendering resolution without understanding how this affects the load on the GPU. Let's start by analyzing what exactly is eating up your performance and move on to step-by-step settings.
Optimal graphics settings within the game
The most obvious, but often ignored stage is the internal settings menu Genshin Impact. The developers have provided flexible tools that allow you to disable resource-intensive effects individually. Many players make the mistake of selecting the “Low” preset, but leaving certain “heavy” features enabled, which negate the entire optimization. The key parameter here is not the overall quality, but specific items that affect the load on the video processor.
Pay special attention to the “Shadows” parameter. Real-time dynamic shadows require enormous computing power. If your goal is maximum FPS, and not an ideal picture for screenshots, this item must be disabled completely or set to minimum. The same goes for anti-aliasing: enabling MSAA x2 or x4 creates additional load, which on smartphone screens with high DPI (pixel density) is often invisible to the eye, but is critical for the processor.
⚠️ Attention: Do not set the frame rate to “60 FPS” if your battery is worn out or the device is prone to throttling. It is better to select “30 FPS” or “Energy Saving” to ensure stability without sudden drops of up to 15 frames during battle.
It is also worth experimenting with the quality of character shadows and post-processing. These effects add a “cinematic” feel, but in dynamic combat they only interfere with the view and load the system. Disabling volumetric fog and water reflections in the graphics settings can give a performance increase of up to 5-7 frames per second in open locations. Remember that each slider in the menu is a separate algorithm that your phone must calculate 60 times per second.
Use the "Reset Settings" function in the graphics menu before manual tuning to ensure that any hidden settings have not previously been changed by third-party apps.
- 📉 Shadow quality: Set to "Very Low" or "Off" for maximum gains FPS.
- 🌊 Reflections: Turn off reflections of water and the environment, they are the least noticeable in battle.
- ⚡ Frame rate: Choose the value that your phone holds stable 100% of the time, and not the one it only reaches in the menu.
- 👤 Shadows characters: System optimization and game mode Modern Android shells, such as Samsung, Xiaomi or Oppo, have built-in game centers. These system add-ons are not just marketing - they actually reallocate processor resources, giving priority to the active game window. Activating the game mode often allows you to block background notifications and prevent the game from minimizing when there is an incoming call, which saves resources on re-loading textures. Reducing this parameter has little effect on the visuals, but relieves the CPU during massive battles.
System optimization and game mode
Modern Android skins such as OneUI from Samsung, MIUI/HyperOS from Xiaomi or ColorOS from Oppo, have built-in gaming centers. These system add-ons are not just marketing - they actually reallocate processor resources, giving priority to the active game window. Activating game mode often allows you to block background notifications and prevent the game from minimizing when there is an incoming call, which saves resources on re-loading textures.
In the battery settings, you need to find a specific application Genshin Impact and change the power saving mode to “No restrictions” or “High performance”. By default, the system tries to limit the processor frequency to save battery, which leads to micro-lag. By allowing the game to consume more power, you remove the artificial limits imposed by the operating system. However, be prepared for the fact that battery consumption will increase in proportion to the increase in performance.
Don't forget about the Do Not Disturb function. The vibration motor and sound notifications consume input controller resources and can cause short-term input lags. The game center of most smartphones has an option to lock the brightness and navigation buttons, which also prevents accidental minimization. If you have a phone with a high screen refresh rate (90 Hz or 120 Hz), try to force the system screen settings to set 60 Hz for the game, since the Genshin engine still does not support the values, and the system will waste resources on rendering extra frames of the interface.
Game mode of a smartphone is not just blocking calls, it is a system priority that prevents the OS from “putting to sleep” the processor cores during the game.
Cleaning RAM and cache
Genshin Impact is known for its “voracious” appetite for RAM. Over time, temporary files, error logs, and old resources accumulate in the game cache, which may conflict with new updates. Regularly clearing the cache through the app settings is a safe procedure that does not delete your progress (since it is stored on the server), but frees up space for quickly loading new textures.
Before starting the game, it is recommended to close all background applications. Browsers with dozens of tabs, social networks and instant messengers take up valuable megabytes of RAM. If your smartphone has 4 GB or 6 GB of RAM, the system may begin to actively use the swap file on the internal storage, the speed of which is significantly lower than the speed of the RAM. This leads to noticeable stuttering when switching between characters or loading new zones.
Settings → Applications → Genshin Impact → Storage → Clear cacheThere is a myth that memory cleaning apps (“process killers”) are useful. In fact, aggressively terminating processes can be harmful. The Android system itself manages memory efficiently, and third-party utilities often simply restart services, creating additional load on the processor. It is better to use the built-in cleaning tools that smartphone manufacturers offer in the device maintenance menu.
☑️ Preparing memory before the session
Temperature and throttling management
Throttling - This is a mechanism to protect the processor from overheating, in which the system forcibly reduces the clock frequency of the cores. As soon as the temperature reaches a critical point (usually about 45-50 degrees on the case), the FPS in the game can drop from 60 to 20 in a matter of seconds. This is the main reason why the game starts out cheerful, and after 15 minutes turns into a slideshow. Heat control is often more effective than any software setting.
Remove the case while gaming. Thick silicone or leather cases work like a thermos, preventing heat from dissipating into the environment. Play indoors with good ventilation or under air conditioning. Direct sunlight hitting the screen will heat up the device faster than the processor, so avoid playing outside in hot weather. Physical cooling is the most effective method of maintaining high frame rates over a long distance.
⚠️ Attention: Never put your smartphone in the refrigerator or freezer to cool it! A sudden temperature change will cause condensation inside the case, which will lead to an irreversible short circuit and damage to the motherboard.
For enthusiasts, there are active cooling systems - coolers with a fan or Peltier elements, which are mounted on the back cover of the smartphone. Devices such as Black Shark or Flydigiare able to remove heat more efficiently than passive dissipation. Using a cooler allows the processor to maintain maximum frequencies (the so-called “boost”) much longer without throttling. This is especially true for owners of processors Snapdragon 888 and 8 Gen 1who are known for their hot temperament.
Why does the phone heat up in Genshin?
The game uses complex shaders, dynamic lighting and constantly loads huge textures of the open world, forcing both the CPU and GPU at its limit at the same time.
Advanced methods: Resolution and scaling
If the standard settings are not enough, you can resort to more radical methods of changing the rendering resolution. Some game centers (for example, Game Turbo Xiaomi) have a function to lower the game resolution. Reducing the resolution from native (eg 2400x1080) to 1600x720 significantly reduces the number of pixels the graphics card needs to render in each frame. The picture will become more “soapy”, but the increase in FPS will be colossal.
For users with superuser rights (Root), there are opportunities to edit the game configuration files, but this is a risky path that can lead to account blocking by anti-cheat. We do not recommend accessing files GraphicsQuality.xml manually if you are not sure of your actions. It is safer to use the built-in scaling functions that some launchers or game shells offer.
| Parameter | Impact on FPS | Impact on quality | Recommendation |
|---|---|---|---|
| Shadows | High (+++) | Medium | Off |
| Smoothing | Medium (++) | Low (on small screens) | Off |
| Volumetric fog | Medium (++) | High | Low |
| Render resolution | Critical (++++) | Critical (blur) | Only for weak PCs/Phones |
It is also worth mentioning the DLSS function or analogues upscaling, but on mobile devices they are still poorly implemented or absent. Instead, some processors MediaTek have proprietary image enhancement technologies that you can try enabling in the display settings, although their effectiveness in games varies from model to model.
If you are using a third-party launcher, make sure that it does not consume a lot of resources on its own. The manufacturer's standard launcher is often better optimized for specific hardware components of the device.
Updating drivers and game versions
Processor manufacturers regularly release GPU driver updates through the Google Play Store (section "Updates for system components" or a separate application Game Driver). These updates contain optimizations for specific popular games, including Genshin Impact. Check for graphics driver updates, as this may fix rendering issues and improve stability without changing settings.
The game itself is also receiving patches that can either improve or degrade optimization. Before major updates, developers often conduct tests on various devices. If after the update the game starts to slow down more, try clearing the cache again, as new files may have appeared “crookedly” on top of old ones. As a last resort, completely reinstalling the game can solve the problem of data fragmentation on the drive.
⚠️ Attention: The settings interface and the names of the items may differ depending on the version of the game and region. If you do not find any item, check the official message from the developers about the latest changes in patch notes.
Make sure that at least 10-15% of the space is free on the internal drive. SSD and flash memory in smartphones work slower when they are full. This affects the loading speed of textures and can cause microfreezes when the game tries to read data from the disk. Regularly delete unnecessary videos and photos, transferring them to your computer or to the cloud.
Timely updating graphics drivers through the Play Market can give a free performance boost that many users are not even aware of.
Frequently asked questions (FAQ)
Will installation help? “pure” Android or custom firmware?
In theory, custom firmware without unnecessary software (bloatware) can free up some RAM and reduce the background load on the processor. However, on modern smartphones the difference will be minimal (1-3 FPS), and the risk of bricking the device or losing the warranty is very high. This is rarely a justified decision for playing Genshin.
Why does the game slow down even at low settings?
There may be several reasons: overheating and throttling, full phone memory, background processes (antiviruses, synchronization) or outdated GPU drivers. It is also possible that a particular location (for example, a city with a large number of NPCs) is simply too difficult for your hardware, regardless of the settings.
Is it safe to use applications for overclocking the processor (GPU Overclock)?
Strongly not recommended. Forced overclocking without proper cooling will lead to instant overheating, rapid battery wear and possible processor failure. Anti-cheat games can also regard interference in system files as cheating and block the account.
Does Internet speed affect the FPS in the game?
No, Internet speed only affects the delay in data transfer (ping) and the speed of loading resources. Low FPS is a problem with your phone's CPU and GPU power. However, with a very poor connection, teleportation lags may occur, which are visually similar to graphics brakes.
Is it worth disabling animations in the developer settings?
Disabling window animations (scale_window_animation) can make the system interface more responsive, but this has virtually no effect on the rendering of the game inside the window. This is more of a cosmetic measure for the overall feeling of smartphone performance, rather than a real boost for the game engine.
