AMD introduces ray tracing support in open source Vulkan graphics drivers for RDNA 2 GPUs in Linux

Over the past week, the AMD Vulkan graphics driver, AMDVLK GPU UnlockedIncreased 64-bit ray tracing support for Radeon RX 6000 GPUs. This includes both desktop/mobile GPUs and APUs that use the RDNA 2 graphics architecture. It will now support all AMD Vulkan drivers across all platforms, such as Mesa3D RADV and AMDVLK GPUOpen and AMDGPU-PRO Device ray tracing.

AMDVLK GPUOpen, AMD’s open source Vulkan driver, supports hardware ray tracing for RDNA 2 GPUs in Linux

The GPU is included in the new updates ray tracing Library, or GPURT, which will consist of the Bounding Volume Hierarchy (BVH), building and sort processing found in ray tracing using shaders such as HLSL. This library will allow the standard library to start more standardization and improve graphics rendering. The new library will also be compatible with DirectX 12 DXR.

GPU ray tracing (GPURT) library as “a static (delivery source) library that provides ray tracing-related functionality for AMD drivers that support DXR (DirectX 12) and the VulkanĀ® RT API.” The library was built on the company’s Platform Abstraction Library (PAL).

The GPURT library uses the C++ interface as its basis. The public interface is divided into multiple header files based on their dependencies and usage. Users interested in full information on the RDNA 2 GPU Ray Tracing Library (GPURT), along with chassis details, can learn more on the official GitHub page.

Here is information on the latest update for AMDVLK GPUOpen v-2022.Q3.4:

New features and improvement

  • Add 64-bit ray tracing support for Navi2x
  • Update Vulkan headers to 1.3.225
  • Performance tuning for games: World War Z, Ashes Of The Singularity

Fix the problem

  • CTS failed for the new version in dEQP-VK.api.copy_and_blit..resolve_image.whole_copy_before_resolving_transfer.
  • CTS warning in dEQP-VK.pipeline.creation_cache_control. *
  • VulkanInfo crashes with pipeline cache disabled
  • RGP Test Kit Fails on the RX 6800
  • Firefox corruption on Ubuntu 22.04

Users who are interested in installing the latest version of AMDVLK GPUOpen v-2022.Q3.4 can find installation instructions over here. As with installing any new software, hardware, or drivers, users should back up any relevant data so they don’t lose essential files during updates.
