Runtime Libraries 1.0.39.1 — Vulkan
The (specifically version 1.0.39.1) are the execution files required by games and software to communicate with your graphics hardware using the Vulkan API. Without these libraries installed, any game built to run on Vulkan will fail to launch or experience major performance issues. How Did It Get on Your Computer?
It serves as a communication layer between a game or application and the computer's graphics hardware. Unlike older APIs like OpenGL, Vulkan allows for better CPU/GPU balance, potentially increasing performance in supported games.
Compared to older APIs like OpenGL or even DirectX 11, Vulkan offers two major advantages: Vulkan Runtime Libraries 1.0.39.1
In many cases, particularly with NVIDIA drivers, this installation occurs automatically, even if you choose a "custom" installation, providing no option to deselect it. Because the installation happens in the background as part of a routine driver update, you likely never saw a pop-up notification or a dedicated installation wizard, leading to the understandable surprise when you later discovered it in your list of programs.
The Vulkan runtime libraries are digitally signed by The Khronos Group or by the GPU vendor (NVIDIA/AMD). You can verify this by: The (specifically version 1
Yes. Is it a virus? No (though you should verify the file location). Can I uninstall it? You shouldn't; it is required for modern PC gaming and graphics performance.
Uninstalling this program will not harm your operating system, but it will break functionality for any video games, emulators, or professional rendering engines that rely on the Vulkan API. Games like Doom , No Man's Sky , Baldur's Gate 3 , and various Nintendo Switch or PlayStation emulators utilize Vulkan heavily. It serves as a communication layer between a
Keeping 1.0.39.1 is perfectly fine for running older Vulkan-enabled games. Troubleshooting: How to Update or Reinstall
When a game or application wants to use Vulkan, it loads this DLL, which then:
Like any piece of complex software, the Vulkan Runtime Libraries are versioned. The version number 1.0.39.1 is a specific build from the development cycle of the Vulkan API. To understand its place in history, it’s helpful to know a few key dates:
