This is the question many people ask themselves when they meet Vulkan RT in their programs.

At first glance, it looks almost like a virus.

But don’t worry about it. It’s not dangerous.

Vulkan RunTime Libraries, also known as Vulkan Runtime Libraries or VulkanRT, is installed by graphics card manufacturers such as NVIDIA, Intel or AMD when your video driver is last updated. It is not malware or viruses, but a 3D graphics and computer API from the Khronos group.

The objective is to reduce overhead costs, control the GPU more directly and reduce CPU usage. You can compare it to Direct3D and Mantle if it helps you understand. Some mentioned that it may be necessary in new games (e. g. Steam) or graphic applications.

Since it is an application for cross-platform 3D graphics, it can be useful for playing games or interactive multimedia applications. However, if you have no use for the application, you can uninstall it from the Control Panel, that’s how it works here:

What is the relationship with Vulkan runtime libraries?

If you are not sure if you have Vulkan Run Time Libraries installed on your computer, do the following

  • Hold down the Windows key and press R
  • Enter appwiz.cpl and press Enter.
  • Scroll down and search for a program called Vulkan RunTime Libraries.

You can also search for Vulkan runtime libraries under Settings > Applications.

Some Windows 10 users have reported that after removing the Vulkan Run-Time Libraries, Windows Defender no longer displays notification of malware attacks. There is no link between Vulkan and the win32/subtab!blnk virus.

Should I remove Vulkan?

If you have installed Vulkan on your computer, you are probably a PC player. Since it is only downloaded with the latest graphics card drivers, you will not get Vulkan if you use built-in graphics for basic PC tasks.

If you find it, it means that the Vulkan runtime libraries are still present and if not, you must install it. Sometimes, Windows Defender or an antivirus can mark Vulkan as a threat, but this is not the case. So don’t take it off.
