AMD today released the latest version of the Radeon Software Adrenalin drivers. Version 21.6.2 beta comes with support for real-time raytracing in "DOOM Eternal," the first game to implement Vulkan RT. The drivers also add support for a handful new Vulkan API extensions, including "VK_EXT_custom_border_color," "VK_KHR_shader_subgroup_uniform_control_flow," and "VK_EXT_color_write_enable." Among the handful issues fixed are visual artifacts on "MechWarrior 5 : Mercenaries" in DirectX 11 mode, on Radeon RX 6000 series; the "Error 184" message when running AMD's auto-detect and install drivers mode on Windows 7; and an application freeze noticed with Adobe Substance 3D Painter on some RX 6000 series graphics products.

Support For

• DOOM Eternal next-gen update
• Vulkan raytracing

Added Vulkan Support

• VK_EXT_custom_border_color: This extension allows applications to specify a custom border color for when the sampler address mode VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_BORDER is used.
• VK_KHR_shader_subgroup_uniform_control_flow: This extension exposes the availability of the SPV_KHR_subgroup_uniform_control_flow SPIR-V extension for shader modules use. The SPIR-V extension provides stronger guarantees that diverged subgroups will reconverge.
• VK_EXT_color_write_enable: This extension allows applications to selectively enable and disable writes to output color attachments via a pipeline dynamic state. This has the potential to reduce pipeline counts for increased efficiency.

Fixed Issues

• While playing MechWarrior 5 : Mercenaries on DirectX 11, visual artifacts may be observed on some AMD Radeon graphics products such as Radeon RX 6000 series graphics products.
• An error message - Error 184 - may be received after running the AMD Auto-Detect and Install Updates utility program on Windows 7 based systems.
• Adobe Substance 3D Painter may freeze while running this application on some AMD Radeon graphics products such as Radeon RX 6900.

Known Issues

• Some users may experience elevated memory usage by AMD User Experience Program. A temporary workaround is to opt-out of the AMD User Experience Program. Learn more from AMD here on how to opt out of the program.
• Resident Evil Village may experience an intermittent application hang or TDR on AMD Radeon VII graphics products in the first mission of the game.
• Enhanced Sync may cause a black screen to occur when enabled on some games and system configurations. Any users who may be experiencing issues with Enhanced Sync enabled should disable it as a temporary workaround.
• Connecting two displays with large differences in resolution/refresh rates may cause flickering on Radeon RX Vega series graphics products.
• An Oculus service error may be received on Radeon RX 5000 & 6000 series graphics products which prevents the Oculus Link setup software from running.
• Radeon performance metrics and logging features may intermittently report extremely high and incorrect memory clock values.
• If Ryzen Master is not detected in Adrenalin software after installation, a system restart may be required.
• If Blue or Black screen is observed in mobile systems, temporarily disable Enhanced sign-in
• A driver mismatch error may appear when two versions of Radeon software (Windows Store & AMD Support versions) are installed on your system. As a temporary workaround, launch the Windows Store version of Radeon software.
• AMD is investigating an issue that may cause a small impact to battery life on AMD Ryzen 5000 notebooks.
• A Blue or Black screen may be observed after updating to the latest Radeon Software. A workaround is to disable core isolation.
• AMD is investigating a D3 code that may be seen in some motherboard after updating to the latest Radeon Software.
• Lower than expected performance may be observed on select AMD Athlon mobile systems.
