Vulkan® OoORasterization

The Vulkan® out-of-order rasterization sample shows how to use the out-of-order rasterization extension

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® 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.


  • 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.
