It’s built on top of the Anvil framework, which simplifies the development of Vulkan® applications. You can read more about Vulkan® on our dedicated page:

Vulkan®

Vulkan® gives software developers control over the performance, efficiency, and capabilities of AMD Radeon™ GPUs and multi-core CPUs.

On GCN GPUs supporting the extension, you can toggle between relaxed and strict rasterization orders by pressing the space key. The background color will also change to indicate a mode switch.

Requirements

• AMD Radeon™ GCN-based GPU (HD 7000 series or newer)
  • Or other Vulkan® compatible discrete GPU.
• Windows® 7 (SP1 with the Platform Update), Windows® 8.1, or Windows® 10
  • Or Linux (Ubuntu)
• Visual Studio® 2013 or Visual Studio® 2015
  • Or on Linux, anything supported by CMake that has a proper C++11 compiler.
• Graphics driver with Vulkan® support
  • For example, AMD Radeon™ Software Crimson Edition 16.5.2 or later.
• The Vulkan® SDK must be installed.
