AMD has released its new Radeon Adrenalin 19.6.2 driver which improves the support for the Vulkan API on Radeon GPUs.

Aside from the above mentioned improved Vulkan support, AMD Radeon Adrenalin 2019 Edition 19.6.2 also addresses various issues, including a timeout that occurred when exiting some gaming applications that are using DX12 when multiple displays are connected and in clone mode. In addition, the new driver fixes an issue that causes performance drops with Wireless VR across multiple game titles on some Radeon RX 400 and Radeon RX 500 GPUs.
