The "Not Enough VRAM" error in Stalker 2: Heart of Chernobyl typically occurs when your graphics card lacks sufficient video memory to handle the game's settings or assets. Here are some steps to address and resolve the issue


1. Lower In-Game Graphics Settings
Reducing the graphical load on your GPU can prevent VRAM-related errors:- Resolution: Lower the game resolution (e.g., from 4K to 1080p).
- Texture Quality: Set textures to "Low" or "Medium," as high-resolution textures consume significant VRAM.
- Ray Tracing: Disable Ray Tracing, as it demands additional VRAM.
- Anti-Aliasing: Reduce or turn off anti-aliasing.
- Shadow Quality: Set shadow quality to "Low" or "Medium."
- View Distance: Reduce the draw distance.
2. Use DLSS/FSR (If Supported)
- DLSS (NVIDIA) or FSR (AMD) upscales the game from a lower resolution, reducing the load on your GPU and VRAM while maintaining visual quality.
- Enable this feature from the game’s graphics menu if available.
3. Adjust Launch Options
Some launch options can help optimize VRAM usage:- Open the game launcher (Steam or Epic Games).
- Go to the launch options section.
- Add the following commands (adjust according to your VRAM):
Diff
Copy code
<span>-dx12 -low -heap size <value></span><br>
Replace <value> with half of your system RAM in kilobytes (e.g., -heap size 8388608 for 16GB of RAM).
4. Update Your Graphics Drivers
Outdated drivers can lead to VRAM errors:- Update your GPU drivers from the official sites:
- NVIDIA
- AMD
- Use a clean installation to ensure there are no lingering issues.
5. Free Up VRAM Resources
Ensure your GPU's VRAM isn't being used by background applications:- Close unnecessary applications that might be consuming VRAM (e.g., Chrome, video editing software).
- Disable overlays from apps like Steam, Discord, or GeForce Experience.
- Check Task Manager for GPU memory usage and end high VRAM-consuming tasks.
6. Optimize Windows Settings
- Set the Game to High Performance:
- Go to Windows Settings > System > Display > Graphics Settings.
- Add Stalker 2 and set it to High Performance.
- Disable Background Processes:
- Use Task Manager to stop unnecessary programs.
- Disable GPU Hardware Acceleration in applications like Discord or browsers.
7. Increase Virtual Memory
If your system is low on available memory:- Open Control Panel > System > Advanced System Settings > Performance > Advanced > Virtual Memory.
- Set a custom size:
- Initial Size: 1.5x your RAM (e.g., 24GB for 16GB RAM).
- Maximum Size: 3x your RAM.
- Restart your PC after applying the changes.
8. Check Hardware Requirements
Ensure your GPU meets the game's VRAM requirements:- Minimum: 4GB VRAM.
- Recommended: 6GB-8GB VRAM or more for higher settings.
9. Update or Reinstall the Game
Sometimes the issue lies in corrupted game files:- Verify the game’s integrity through Steam or Epic Games Launcher.
- Update the game to the latest patch.
