How to Fix Subnautica Crashes on PC

Development

Subnautica is an immersive open-world survival game set in an alien underwater world. While its beauty and depth (pun intended) have earned it a dedicated fanbase, some players on PC have encountered frustrating crashes that disrupt gameplay. If you’re struggling with Subnautica crashing frequently, you’re not alone—and fortunately, there are proven steps you can take to stabilize the game. In this article, we will walk you through common causes and effective solutions to help you get back to exploring the depths safely.

1. Check the Minimum System Requirements

Before troubleshooting game-specific settings, it’s essential to ensure your PC meets the game’s hardware requirements. Subnautica is graphically demanding and requires a modern setup to run reliably.

  • OS: Windows 7 64-bit or later
  • Processor: Intel Haswell 2 cores / 4 threads @ 2.5GHz or equivalent
  • Memory: 8 GB RAM
  • Graphics: Intel HD 4600 or better, capable of running DirectX 11
  • DirectX: Version 11

If your system falls below these specifications, consider upgrading your hardware or lowering in-game graphics settings.

2. Update Graphics Drivers

Outdated or corrupted graphics drivers are one of the most common causes of crashes in modern games. Ensure that your graphics drivers are up to date.

Follow these steps based on your GPU:

After updating, restart your PC and try launching Subnautica again.

3. Verify Integrity of Game Files

Corrupted or missing game files can lead to persistent crashes. Steam offers a built-in tool to verify and repair these files.

To verify game integrity on Steam:

  1. Open Steam and navigate to your Library.
  2. Right-click on Subnautica and select Properties.
  3. Go to the Installed Files tab.
  4. Click on Verify integrity of game files.

This process may take several minutes. If any files are missing or corrupted, Steam will re-download them automatically.

4. Lower In-Game Graphics Settings

Subnautica’s high-resolution textures and real-time water rendering can tax even strong PCs under certain scenarios. If the game crashes during graphically intensive scenes or load screens, consider reducing visual fidelity to improve stability.

Settings to adjust for better stability:

  • Resolution: Lower the in-game resolution
  • Anti-Aliasing: Set to off or low
  • Shadow Detail: Set to low
  • Water Quality: Medium or low

Apply changes and restart the game to test performance improvements.

5. Disable Background Programs
