First release of Vulkan will go live on PC in patch 4.3. To launch Rainbow Six Siege on Vulkan, please select the appropriate play button when launching the game on PC. You will be able to select either DirectX 11 or Vulkan on your launchers.
WHY VULKANThe Vulkan API provides advantages over DirectX 11 that can help Rainbow Six Siege improve performance on a number of levels.
In brief, the Vulkan API will enable us to make improvements on workload through Dynamic Texture Indexing to reduce CPU cost, and Dynamic Resolution and AsyncCompute to reduce GPU cost. These features are already used on consoles, and the Vulkan API will allow us to do the same for PC. By combining all these features, we can optimize both the GPU and CPU cost of rendering.
