AMD Radeon 19.6.2 driver brings in further Vulkan extensions support

Following AMD's previous graphics driver that landed during E3 week with Xbox Game Pass for PC support, today the red team delivered its Radeon Software Adrenalin 2019 Edition 19.6.2 driver.

Just as with the previous release, AMD hasn't detailed any specific games that have received optimizations with this driver, but support for a number of Vulkan API Extensions, including a couple that improves HDR support, has landed with it alongside bug fixes.

Here are the Vulkan extensions arriving with the driver, as well as AMD's descriptions of them:

  • VK_EXT_host_query_reset
    • Allows resets of queries from the host, rather than on the GPU.
  • VK_EXT_full_screen_exclusive
    • Gives applications explicit control over exclusive full-screen modes (this is for instance useful for HDR support).
  • VK_AMD_display_native_hdr
    • Exposes FreeSync2 capabilities for improved HDR support.
  • VK_EXT_separate_stencil_usage
    • Separates the usage flags for depth/stencil aspects of a depth/stencil image making it possible to restrict/expand the usage relative to the depth aspect.
  • VK_KHR_uniform_buffer_standard_layout
    • Provides more flexible alignment for uniform buffers, enabling among other things, the usage of std430 layouts in Vulkan.

And here are aforementioned bug fixes of this driver and the known issues to keep an eye out for:

Fixed Issues

  • Wireless VR may experience performance drops across multiple game titles on some Radeon RX 400 and Radeon RX 500 series graphics products.
  • Performance Metrics Overlay may fail to enable or may be disabled when toggling Radeon Overlay while in game.
  • A TDR may occur when exiting some gaming applications that are using DirectX®12 API when multiple displays are connected and in clone mode.
  • Microsoft® PIX tool may fail when a GPU is connected using AMD XConnect™ Technology.
  • Crackdown™3 may experience an application or game hang on Radeon R7 370 series graphics products.

Known Issues

  • Radeon ReLive streaming and uploading of videos and other content to Facebook™ is currently unavailable.
  • ASUS TUF Gaming FX505 may experience discrete GPU connection issues with devices disappearing from device manager when the system is idle.
  • Performance Metrics Overlay and Radeon WattMan gauges may experience inaccurate fluctuating readings on AMD Radeon VII.
  • ACER Swift 3 with AMD Ryzen Processor may experience system instability when upgrading to Radeon Software Adrenalin 2019 Edition 19.6.2 using the Custom Clean Installation option.
  • Graphics driver may not uninstall correctly when using the express uninstall option on some Ryzen APUs.

Radeon Software Adrenalin 2019 Edition 19.6.2 driver is now available as an optional upgrade straight through the Radeon Settings app on Windows. AMD users can also head over to the driver's release notes page to grab separate download links.
