AMD today released its first drivers to implement Microsoft's DirectX Agility SDK version 1.613, which introduces the new DirectX 12 Work Graphs 1.0 API. AMD has extensively worked on implementing the new technology, which among other things, significantly reduces the CPU's role in most common shader graphics workloads, and improve GPU shader thread saturation, as the GPU waits less on the CPU's share of shader workloads. The new AMD Software Adrenalin 23.40.14.01 drivers are off the main driver update channel, and is intended for developers and enthusiasts to start exploring GPU Work Graphs. GPU Upload Heaps, and certain features of Shader Model 6.8 on supported AMD Radeon GPUs. There are some known issues with the driver specific to AMD's implementation of GPU Work Graphs, and the latest version of the Agility SDK in general, which are listed below.
