AMD today has released its new Radeon Software version 21.6.2 display driver. The update is the second driver of this month and the major highlight of this release brings optimization for Doom Eternal that recently gained ray-tracing (RTX) and DLSS features and is available today. The driver also adds several new Vulkan extensions. They are:

• 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.

As usual, the driver brings a few fixes for bugs which are listed below:

• 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.

There are also several issues, both new and some old, that remain unresolved:

• 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.

• 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.

The AMD Link for Windows issue still remains:

• Intermittent grey frame corruption might be observed when streaming with HEVC on certain configurations via an Internet connection. A workaround is to use the AVC encoding setting instead.

With its previous release version 21.6.1, AMD dropped support for pre-Windows 10 systems and pre-Polaris graphics cards, and the new 21.6.2 is no exception. So for those with a compatible system who wish to update to this driver, you can find the download link on the official release notes page.

For owners of Nvidia GPUs, a Game Ready GeForce driver for Doom Eternal RTX update was already released last week, which you can find here.
