Intel demonstrated the capabilities of the Vulkan API at the recent SIGGRAPH 2015 event. This weekend it made a video available featuring its Stardust graphics demo running on a Windows machine powered by an Intel quad-core processor, comparing the performance when switching from OpenGL to Vulkan APIs. The new API made quite a difference. Vulkan was announced in March this year.
