AMD has uploaded its Radeon Adrenalin 2020 21.6.1 video card driver. There are some big changes here, especially in terms of compatibility.

Older GPUs and Windows 8.1 no longer supported

This is the first AMD video card driver that exclusively supports Windows 10 (64-bit). AMD no longer supports Windows 8.1 or earlier versions of Windows.

Furthermore, big cuts have been made to the number of supported video cards. Starting with version 21.6.1, AMD is no longer supporting a bunch of older models, only the Radeon RX 400 series and newer are supported. This means you will need the 21.5.2 driver for older models, including the Radeon HD 7000, Radeon HD 8000, Radeon 200, and Radeon 300 series. The newest cards that are on the chopping block date back to late 2015.

NVIDIA recently announced it would end Kepler support with the R470 driver branch.

FSR launches

The 21.6.1 release introduces support for the Radeon RX 6800M laptop GPU and is the first to support AMD FidelityFX Super Resolution (FSR). There is not a lot of information on AMD's website yet. A leak from a week ago indicated there would be seven games with FSR support at launch. Do note that FSR support also requires a video game patch. FSR is a new technique from AMD that promises to increase the framerate via upscaling technology. It's similar to NVIDIA's DLSS technology, but without machine learning.


Support For
  • AMD Radeon™ RX 6800M Graphics
  • Dungeons & Dragons: Dark Alliance™
  • AMD FidelityFX Super Resolution (FSR) support for select titles.

    Fixed Issues
  • Radeon FreeSync™ may intermittently become locked while on desktop after performing task switching between extended and primary displays upon closing a game, causing poor performance or stuttering.
  • Anno 1800™ may crash upon launching this game when running DirectX®12.
  • AMD cleanup utility may clean up chipset/RAID installer related folders/registries from the system.
  • Some Radeon Graphics products may experience lower than expected performance in Destiny 2™ when compared to previous Radeon Software versions.
  • Upon joining the AMD User Experience Program, the AMD User Experience Program Master service may have higher than expected CPU utilization.
  • Enabling Ray Tracing while running Ring of Elysium™ on DirectX®12 may cause this game to crash.

    Known Issues
  • 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 error 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.
