AMD kicks off the new week with a fresh driver. The firm's Radeon Software Adrenalin 2020 Edition 21.2.3 release can be downloaded over here. It adds support for DIRT 5 Energy Content Pack and has some bug fixes -- including patches for two HDMI-related bugs.
Support For
  • DIRT 5™ Energy Content Pack

    Fixed Issues
  • HDMI Audio Devices may fail to install on Radeon RX 400 and Radeon RX 500 series graphics products.
  • Hot plugging HDMI TV displays in multi monitor system configurations may sometimes cause a system crash or hang.
  • An application crash or hang may occur in Substance Painter™ on Radeon RX 6000 series graphics products.
  • A system crash or hang may occur on the HP Reverb G2™ when connected to Radeon RX 6900 series graphics products.
  • Radeon Software may sometimes fail to gather the latest available Radeon Software versions when performing or checking for updates.

    Known Issues
  • 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. A temporary workaround is to disconnect the headset before install.
  • AMD is currently investigating end user reports that Radeon Software may sometimes have higher than expected CPU utilization, even when a system is at idle. Users who are experiencing this issue are encouraged to file a bug report in Radeon Software.
  • 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.
