How To Fix Black Myth: Wukong Out of Video Memory Error on PC

Black Myth: Wukong has shot to the top of the charts pretty fast and has an overwhelmingly positive rating on Steam (at the time of writing) But it isn't completely flawless with some optimisation issues and errors popping up here and there. The most common being an "Out of Video Memory" which claims there is a memory issue, even on devices running RTX 4090s and bucket loads of RAM. There are a few potential solutions getting around though that help.

How To Fix Black Myth: Wukong Out of Video Memory Error on PC

We will ultimately be waiting for an official patch that solves this issue properly there are a few steps you can take to solve this issue without waiting. Most of which are basic checks and reconfigurations, so work your way through the list and see what works. Before doing so though, make sure that you have the latest BIOS installed on your computer. Especially if you are using an Intel CPU.

It is a Long Shot but Clean install your GPU Drivers with DDU.

Instead of the standard driver uninstallation method via the Control Panel, try using Display Driver Uninstaller (DDU).

• Download Display Driver Uninstaller

• Download the latest graphics drivers for your hardware, then disable your Internet connection.

• Open it then select the option to remove GeForce Experience (GFE) if prompted. (Remove the AMD software if you are using AMD)

• After the process is complete, restart your computer.

• Reinstall your graphics drivers, ensuring your internet connection is re-established to prevent Windows from automatically installing generic drivers.

• After reinstalling your drivers, re-download GeForce Experience and update your drivers as needed. If the issue persists, repeat the process.

Disable Fullscreen Optimizations for Black Myth: Wukong

Windows applies fullscreen optimizations to most games and applications, which can sometimes cause issues, including the "out of video memory" error in Black Myth: Wukong. Disabling fullscreen optimizations might help resolve this issue. Here's how:

• Open your Steam library and right-click on Black Myth: Wukong.
• Select Manage > Browse local files.
• In the game’s directory, right-click on the game’s executable file and select Properties.
• Go to the Compatibility tab.
• Check the box next to Disable Fullscreen Optimizations.
• Click Apply and OK.

Now, launch Black Myth: Wukong again to see if the error is resolved.

Run Black Myth: Wukong at a Lower Rendering Resolution

The resolution of your game directly impacts VRAM usage. Higher resolutions require more VRAM, which can lead to the "out of video memory" error if your GPU doesn't have enough VRAM or if there’s a memory leak. Try lowering the rendering resolution to fix this issue:

• Method 1: Change the game’s resolution. For example, if you’re running the game at 1440p, try lowering it to 1080p.
• Method 2: Adjust the resolution scale slider within the game settings, which reduces rendering resolution while maintaining your native display resolution.

By reducing the resolution or resolution scale, you should lower VRAM usage and potentially fix the error.

Enable Sysmem Fallback Policy

This error is common in games running on Unreal Engine 5. Nvidia provides a “Sysmem Fallback Policy” option in its Control Panel that can help alleviate this issue. Follow these steps to enable it:

• Open the Nvidia Control Panel.
• Navigate to Manage 3D Settings > Program Settings.
• Select Black Myth: Wukong from the drop-down menu.
• Find the CUDA – Sysmem Fallback Policy option.
• Choose Prefer Sysmem Fallback.
• Apply the changes.

Restart the game to see if the “out of video memory” error is fixed.

Disable CPU Overclock or Undervolt CPU

Issues with Intel’s 13th and 14th-generation CPUs have been known to cause the “out of video memory” error in Black Myth: Wukong. If you’re using one of these CPUs, try undervolting it as a workaround:

• Using Intel Extreme Tuning Utility:

  • Download and open Intel’s Extreme Tuning Utility.
  • Lower the Performance Core ratio to 53 or 54 to fix the error.

• Using Windows Power Efficiency Mode:

  • Open Windows Settings.
  • Go to System > Power.
  • Select Best Power Efficiency under Power Mode.

Also if you've overclocked your CPU, revert to default clock settings to avoid the error.

Use Recommended GPU and Memory Clocks

Graphics cards from third-party manufacturers often come factory overclocked, which might cause the game to crash. You can revert to Nvidia’s recommended settings by enabling Debug Mode:

• Open the Nvidia Control Panel.
• Go to Help.
• Check the Debug Mode option.

This setting will force your GPU to use Nvidia’s default GPU and memory clocks, potentially fixing the issue.

Increase Black Myth: Wukong’s Shader Cache Size

Unreal Engine games often rely on shader caches for rendering. Increasing the shader cache size can help if the default size is insufficient, potentially causing the "out of video memory" error:

• Open the Nvidia Control Panel.
• Navigate to Manage 3D Settings > Global Settings.
• Scroll down to Shader Cache Size.
• Select 10 GB and apply the changes.

Delete DirectX Shader Cache

Corrupted DirectX shader caches, often due to Windows updates, can lead to the "out of video memory" error. To resolve this:

• Open Windows Settings.
• Go to System > Storage > Temporary Files.
• Check DirectX Shader Cache and click Remove Files.

This will delete the cache, which will be regenerated when you launch the game.

Increase Virtual Memory Size

Insufficient virtual memory can cause Black Myth: Wukong to crash. Increase the virtual memory size as follows:

• Open Windows Settings and navigate to About > Advanced System Settings.
• Under Performance, click Settings.
• Go to the Advanced tab and click on Change under Virtual Memory.
• Uncheck Automatically manage paging file size for all drives.
• Select a drive with at least 32 GB of free space.
• Choose Custom size and set the Initial size to 16,384 MB and the Maximum size to 32,768 MB.
• Click OK and restart your PC.
