Lower the Settings
This is the most straightforward yet effective advice. Although the game has high system requirements, it can run adequately on budget gaming PCs. Plus, this is the simplest optimization method as it requires no additional editing or installation.
Below are the best settings to find a balance between performance and graphics:
- Screen Mode: Choose "Exclusive Fullscreen" for more stable FPS.
- Display Resolution: Set your monitor's native resolution to avoid distortions and reduce GPU load.

- Field of View (FOV): Higher values heavily load the system. Find a compromise for smooth gameplay.
- Vertical Sync and Frame Rate: Disable both features for an immediate performance boost.
- Textures: Set to "High" for GPUs with 8GB VRAM or less, and "Ultra" for more powerful systems.
- Reflections and Shadows: These are the most resource-intensive settings. Set them to "Low" or "Medium."
- Global Illumination and Fog: Choose "Medium" and "High" respectively to maintain atmosphere without sacrificing FPS.
- Scaling Method: DLSS (NVIDIA) or FSR (AMD) provide the greatest FPS increase.
- Blur and Sharpness: Disable blur and set sharpness to around 30%.

These are the best performance settings for most PCs without top-tier components. Such adjustments will reduce system load while preserving the essence of Stalker’s world. Adjust each setting to match your hardware to achieve stable FPS and enjoy the game without annoying drops.
Edit Game Files
To achieve maximum performance in Stalker 2 on weaker machines, editing game files can help. This method disables graphical effects and optimizes game resources even when standard settings don't deliver the desired results. Here's a detailed guide:
- Press WIN+R to open the "Run" window.
- Enter %localappdata% and press Enter.
- Navigate to the folder:
- For the WinGDK version: AppData\Local\Stalker2\Saved\Config\WinGDK
- For the Steam version: AppData\Local\Stalker2\Saved\Config\Windows
- Find the GameUserSettings.ini file and open it with a text editor like Notepad++ or the built-in Notepad.
- Add the following block of settings at the end of the file:
[/script/engine.engine]
bSmoothFrameRate=False
[SystemSettings]
r.DynamicGlobalIlluminationMethod=2
r.ContactShadows=0
r.Lumen.Reflections.Allow=0
r.Lumen.DiffuseIndirect.Allow=0
r.LumenScene.Lighting.AsyncCompute=1
r.MaterialQualityLevel=0
r.Nanite.MaxPixelsPerEdge=4
r.Shadow.CSM.MaxCascades=0
r.ShadowQuality=0
r.VolumetricCloud=0
r.Volumetricfog=0
r.Streaming.LimitPoolSizeToVRAM=1
r.AsyncCompute=1
r.UseAsyncShaderPrecompilation=1
r.Streaming.DefragDynamicBounds=1
r.Streaming.MaxTempMemoryAllowed=512
r.Streaming.PoolSize=6144
r.RenderTargetPoolMin=400
r.Streaming.FramesForFullUpdate=10
r.Streaming.Boost=1.0
s.AsyncLoadingThreadEnabled=1
s.AsyncLoadingUseTimeLimit=1
s.AsyncLoadingTimeLimit=5
s.MinBulkDataSizeForAsyncLoading=0
s.PriorityAsyncLoadingExtraTime=10
[/script/engine.renderersettings]
r.GraphicsAdapter=0
r.TextureStreaming=0
r.DepthOfFieldQuality=0
r.BloomQuality=0
r.FilmGrain=0
r.DisableDistortion=0
r.LensFlareQuality=0
r.Fog=0
r.OneFrameThreadLag=0
- Save the changes using the save button or the Ctrl+S shortcut. To reduce input lag:
- In the same folder, open the Input.ini file.
- Add the following block:
[Engine.InputSettings]
bEnableMouseSmoothing=False ; Disables mouse movement smoothing
bViewAccelerationEnabled=False ; Disables camera acceleration when moving the mouse
- Save the file.
These settings disable some graphical effects, which may degrade visual quality and cause artifacts. However, they significantly improve FPS stability, making them suitable for weaker systems.
