If you’re excited to play Vampire: The Masquerade – Bloodlines 2 but the game keeps crashing with a “LowLevelFatalError” or “An Unreal process has crashed: UE-Bloodlines2” message — don’t worry. You’re not alone. This issue is quite common among PC players, and the good news is, it can be fixed with a few detailed steps.

In this article, we’ll cover every possible solution — from skipping the Paradox launcher to reinstalling drivers and adjusting your system settings — with clear explanations for why each step works.

Fix Vampire: The Masquerade – Bloodlines 2 Fatal Error (LowLevelFatalError / Unreal Process Crash) 🧛‍♂️

Understanding the “LowLevelFatalError” in Unreal Engine Games

Before we dive into the fixes, let’s understand what’s happening.
A LowLevelFatalError is an Unreal Engine crash triggered when the engine fails to access graphics, memory, or configuration data correctly. It’s not specific to Bloodlines 2 — similar crashes have occurred in other Unreal-based games like ARK: Survival Evolved, Fortnite, and Squad.

Common causes include:

  • Corrupted or missing game files
  • Conflicting display or GPU drivers
  • Paradox launcher startup issues
  • Incompatible display mode (fullscreen/windowed)
  • Missing Microsoft Visual C++ runtime files
  • Antivirus blocking the game executable

Now that we understand the roots, let’s go step by step through every possible solution.


1. Run the Game from Installation Folder

The first fix is simple — bypass Steam’s launcher and directly run the executable file.

Steps:

  1. Open Steam.
  2. Right-click Vampire: The Masquerade – Bloodlines 2Manage → Browse local files.
  3. Double-click the .exe file in the Binaries → Win64 folder to launch the game directly.

If it doesn’t open:

  • Right-click the .exe file → Properties → Compatibility.
  • Check Run this program as an administrator.
  • Also try enabling Disable fullscreen optimizations and test.
  • If it still fails, try compatibility mode with Windows 8 or Windows 7.

If you can launch it directly, the problem likely lies in Steam or Paradox’s launcher.


2. Skip the Paradox Launcher

Many players found that skipping the Paradox Launcher helps the game start instantly without crashes.

How to Skip:

  1. Go to your installation folder again and copy the path: C:\Program Files (x86)\Steam\steamapps\common\Bloodlines2\Binaries\Win64
  2. Copy the exact name of the game executable (e.g., Bloodlines2-Win64-Shipping.exe).
  3. Combine the two with a backward slash and add quotes around it, like this: "C:\Program Files (x86)\Steam\steamapps\common\Bloodlines2\Binaries\Win64\Bloodlines2-Win64-Shipping.exe" %command%
  4. In Steam → Properties → Launch Options, paste this line.

This forces Steam to launch the game directly, skipping the Paradox Launcher entirely.


3. Install or Repair Microsoft Visual C++ Redistributables

Unreal Engine games require these runtime components to work properly. Missing or broken files can cause fatal errors.

Steps:

  1. Go to the official Microsoft Visual C++ Redistributables page.
  2. Download both versions:
    • x86 (vc_redist.x86.exe)
    • x64 (vc_redist.x64.exe)
  3. Run both installers.
    • If you see Repair, click it.
    • If you see Install, proceed.
  4. Restart your PC after installation (this step is essential).

After the restart, launch the game again and test.


4. Try Launch Options: DX11 or DX12

Unreal Engine supports multiple DirectX versions. Some users report better stability with DX11, others with DX12.

  1. Open Steam → right-click Bloodlines 2Properties → Launch Options.
  2. Type one of the following: -dx11 or -dx12
  3. Launch the game and see if the crash stops.

If one doesn’t work, try the other. You can remove the command afterward if both fail.


5. Rename the Config Folder

Sometimes the game’s saved settings get corrupted, causing startup failures. You can regenerate a clean config.

  1. Press Windows + E to open File Explorer.
  2. Go to: C:\Users\<YourUsername>\AppData\Local\Bloodlines2\Saved\Config (If AppData is hidden, enable “Hidden items” from the View tab.)
  3. Rename the folder from Config to Config.old.
  4. Restart the game — it will recreate fresh configuration files automatically.

6. Allow the Game in Windows Security and Firewall

Your antivirus or Windows Defender might be blocking the executable.

For Windows Security:

  1. Open Settings → Privacy & Security → Windows Security → Virus & Threat Protection.
  2. Scroll down → Manage Ransomware Protection → Allow an app through Controlled Folder Access.
  3. Add both .exe files (main and Win64 versions) from the game’s directory.

For Firewall:

  1. Go to Control Panel → System and Security → Windows Defender Firewall → Allow an app through Firewall.
  2. Click Change settings → Allow another app → Browse, and add both .exe files.

If you use third-party antivirus (Avast, Bitdefender, Norton, McAfee, etc.), whitelist the same executables there as well.


7. Perform a Clean Installation of Graphics Drivers

Outdated or corrupted drivers are the most common reason for Unreal Engine crashes.

For NVIDIA users:

  1. Visit NVIDIA Drivers.
  2. Select your GPU and operating system.
  3. Download and run the installer.
  4. Choose Custom Installation and check Perform a Clean Installation.
  5. Restart your PC after installation.

For AMD users:

  1. Visit AMD Drivers and Support.
  2. Select your GPU, download, and run the driver setup.
  3. Choose Factory Reset (Clean Install) option.

After reboot, check if the game runs.


8. Run on Dedicated GPU (Disable Integrated GPU)

If you’re on a laptop or dual-GPU system, ensure the game uses your dedicated GPU.

  1. Type Graphics Settings in Windows search and open it.
  2. Click Browse and add your game’s .exe files.
  3. Select each → Options → High Performance → Save.

To disable the integrated GPU:

  1. Right-click Start → Device Manager → Display Adapters.
  2. Right-click your Intel GPUDisable device.
  3. Restart your system and test the game.

Re-enable it later for normal use.


9. Verify Integrity of Game Files

Steam can automatically fix missing or damaged files.

  1. Open Steam → right-click the game → Properties → Installed Files.
  2. Click Verify Integrity of Game Files.
  3. Wait until it finishes and restart your PC.

10. Manage Overlay and Overclocking Apps

Overlays can conflict with Unreal Engine.

Disable or close these:

  • Steam Overlay (in game’s Properties)
  • Discord Overlay (Settings → Game Overlay → Off)
  • NVIDIA GeForce Experience Overlay
  • MSI Afterburner, RivaTuner, or any GPU overclocking software

Make sure only Steam and the game are running before testing again.


11. Update Intel Drivers

If you have an Intel processor, use Intel’s official tool to keep system drivers updated.

  1. Visit Intel Driver & Support Assistant.

Some Unreal Engine games struggle with very high refresh rates (like 240Hz).

  1. Right-click on the desktop → Display Settings → Advanced Display.
  2. Change refresh rate to 60Hz or 120Hz.
  3. Launch the game and test.

15. Increase Virtual Memory

If you’re running low on physical RAM, increasing your paging file can prevent Unreal from crashing.

Steps:

  1. Type View Advanced System Settings and open it.
  2. Under Performance, click Settings → Advanced → Virtual Memory → Change.
  3. Uncheck “Automatically manage paging file size.”
  4. Choose the drive where the game is installed.
  5. Select Custom size and enter:
    • Initial size: 1.5 × RAM (in MB)
    • Maximum size: 3 × RAM (in MB)
      Example for 16GB RAM:
    • Initial: 24576
    • Maximum: 49152
  6. Click Set → OK → Apply → OK and restart.

If it causes instability, revert to System managed size later.
