DOOM Vulkan Support: RX 480 Gets 27% Performance Boost
id Software has released a patch for DOOM that adds support for the Vulkan API on the PC. This means the title would be able to benefit from several great features of the API including Asynchronous Shaders, Shader Intrinsics, as well as Frame Flip Optimizations.
We know that DirectX 12 offers great benefits to gamers on Windows and Xbox but the fact is that majority of gamers are still running Windows 7, and DX12 is not compatible with Windows 7. In comparison, Vulkan API is a low-overhead API that is a descendant of AMD’s Mantle API, and works with Windows 7, 8.1, 10, and Linux.
Developed by the Khronos Group, Vulkan gives developers direct access to GPU resources, offering more efficient muti-threading capabilities while minimizing driver overhead. Since this is an open source API, many game devlopers are hoping the Vulkan support bandwagon, not to mention adopted by both AMD and Nvidia.
In case of DOOM, AMD internal testing shows that up to 27% performance gains were achieved when running Vulkan versus OpenGL on a Radeon RX 480 8GB reference card at 1080p, and up to 23% faster performance at 1440p.
To get the performance enhancements, you will need to download AMD Radeon Software Crimson Edition 16.7.2 drivers. NVIDIA GeForce owners need to be running GeForce 368-69 WHQL drivers however, keep in mind that Vulkan is currently not supported on Nvidia GPUs with 2GB RAM on Win 7.
To enable Vulkan in DOOM, simply head over to the advanced settings menu and switch the Graphics API from OpenGL to Vulkan and wait for changes to take effect. For more details, check out the Vulkan API FAQ over at Bethesda Forums.
