Source: Microsoft One of the big announcements coming from Game Stack Live is a new SDK for DirectX12, dubbed the 'Agility' SDK. With the new Agility SDK, Microsoft is aiming to solve a pain point for developers who say adopting new DirectX12 graphics features is cumbersome. With the Agility SDK, Microsoft will claim that the new features are easier to adopt, won't interrupt or impact existing games, and come with more reliable bug fixes. Microsoft will also demonstrate a range of existing and new DirectX 12 features. Essentially, the Agility SDK allows developers to light up new features for users with compatible systems, namely an updated version of Windows 10 or an Xbox Series S or Xbox Series X console, without impacting users who aren't on the "correct" operating system. The DX12 Agility SDK also comes with a new shader model, dubbed Shader Model 6.6.
