<para>
|
|
Vulkan is a low-level, low-overhead cross-platform API and
|
|
open standard for 3D graphics and computing. It was intended
|
|
to address the shortcomings of OpenGL, and allow developers
|
|
more control over the GPU.

|
Thus, when well optimized, applications written with Vulkan
|
|
in mind perform better than those written in OpenGL. Most
|
|
Windows games are written in DirectX. DXVK, which is
|
|
part of <application>Steam</application>'s Proton and
|
|
<application>Wine</application>, converts DirectX instructions
|
|
to Vulkan calls and has very little overhead. It performs almost
|
|
as good as on Windows, whereas converting the DirectX instructions
|
|
to OpenGL calls has much more overhead.

<para>
|
|
Unlike OpenGL where it had two options to get the libraries
|
|
and possibly cause confusing and extra thought, the Vulkan
|
|
library is supplied directly from KhronosGroup.
