AMD Radeon 21.3.1 driver adds support for RX 6700 XT, Boost and Anti-lag on DX12, plus more

Almost a month after its previous graphics driver release, AMD is back today with a brand new version of its Adrenalin suite. Radeon Software 21.3.1 driver is adding support for the red team's latest Radeon RX 6700 XT graphics launch, the new Doom Eternal expansion, and Radeon Boost and Anti-Lag on DirectX12, and more.

Those who are keen on jumping into id Software's DOOM Eternal: The Ancient Gods - Part Two expansion later today will want to install this driver for the best experience, though AMD didn't elaborate on what exactly are the benefits this time.

Two existing software technologies of AMD - Anti-Lag and Radeon Boost (with Variable Rate Shading for select titles) - have also received updates with this driver to support DirectX 12 for lower latency and higher frame rates in games using the graphics API. Moreover, the driver now carries a built-in stress test for easier performance tuning. There is also support for several new Vulkan extensions, with more details available on the release notes page here.

The fixed issues are as follows:

  • Radeon Software may sometimes have higher than expected CPU utilization, even when a system is at idle.
  • A system hang or crash may be experienced when upgrading Radeon Software while an Oculus VR headset is connected to your system on Radeon GCN graphics products.
  • Minecraft DXR may exhibit corrupted or missing textures when ray tracing is enabled on Radeon RX 6000 series graphics products.
  • An application crash may occur in Call of Duty: Modern Warfare when ray tracing is enabled on Radeon RX 6000 series graphics products.
  • Lighting fails to render correctly on Radeon RX 6800 series graphics products in Star Citizen.
  • A black screen may occur when enabling and disabling Enhanced Sync while vsync is enabled in some Vulkan API games.
  • A black screen or system hang may occur on Hybrid Graphics systems for some Vulkan API games when Enhanced Sync is enabled.
  • Bethesda launcher may experience an application crash on startup when launching some games.
  • Users may be unable to create a new scene in the Radeon Software Streaming tab on first launch or after a settings factory reset.
  • Game specific performance tuning profiles may fail to load when a global performance tuning profile has been created or set.
  • Disabling HDCP support and performing a factory reset and/or system restart may sometimes trigger a system crash or hang on boot.
  • Epic Games social overlay or launcher may exhibit color corruption.
  • Xuan-Yuan Sword VII may experience an application crash with DirectX®12 ray tracing enabled on Radeon RX 6000 series graphics.
  • Color corruption may be experienced in Cyberpunk 2077 when Radeon Boost is enabled.
  • Display flicker or corruption may occur on high refresh rate/resolution multi-monitor system configurations on Radeon RX Vega series graphics.
  • Audio loss or cutout may intermittently occur on some TV displays when Windows audio is set to use 5.1 or 7.1 speaker configurations.

Here are the known issues:

  • The start and cancel buttons in the performance tuning stress test may disappear when Radeon Software is resized to be small.
  • On a limited number of displays, the preferred desktop resolution in Windows may change when the display is power cycled.
  • Enabling vsync in Rocket League and setting the game to use borderless fullscreen may cause stuttering or ghosting.
  • Radeon RX 400 and 500 series graphics products may experience a TDR during extended periods of video playback.
  • Brightness flickering may intermittently occur in some games or applications when Radeon FreeSync is enabled, and the game is set to use borderless fullscreen.
  • 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.

The Radeon Software Adrenalin 2020 Edition 21.3.1 driver is now available for download in the optional section in the Radeon Software app on Windows. Download links can also be found on the aforementioned release notes page.
