AMD has released the Radeon Software Adrenalin 21.3.1 WHQL drivers. These drivers are identical in every way to the 21.3.1 beta drivers from March 18; except with WHQL signing. So, you get “DOOM Eternal: The Ancient Gods Part Two” optimization, support for the recently debuted Radeon RX 6700 series graphics cards, a performance stress test included inside the Performance tab of Radeon Software; four new Vulkan API extensions, and capability updates to Radeon Anti-Lag and Radeon Boost; which now come with support for DirectX 12 and VRS, respectively. The lists of fixed and known issues remain identical, too.
The Radeon Software Adrenalin 21.3.1 WHQL drivers are available online at the AMD driver download page.
