Gaining Extensions!
The Vulkan 1.2 specification was launched on January 15th, 2020, and integrates 23 proven extensions into the core Vulkan API, bringing significant developer-requested access to new hardware functionality, improved application performance, and enhanced API usability.
In October 2020, the Vulkan Working Group released the VK_KHR_fragment_shading_rate extension, which provides a new, flexible technique to control the fragment shading rate, enabling developers to perform shading at a lower resolution than the render targets. This fine level of control allows developers to focus shading resources where they are needed, which ultimately increases rendering performance and quality.
