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).

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:

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:

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:

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:

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:

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:

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:

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:
