The Khronos Vulkan SC Working Group, in collaboration with RasterGrid, today released the Vulkan SC 1.0.21 SDK. This new SDK provides a unified installer for both Linux and Windows platforms, streamlining the development process for Vulkan Safety-Critical applications. Previously, developers needed to install and configure each component separately. The SDK now integrates essential tools such as the Vulkan SC Loader, an emulation driver stack, validation layers, device simulation layers, and pipeline cache utilities into a single package. It also includes CMake and Pipeline Cache Compiler integration, with options for automatic environment setup and compiler discovery during installation. The installers are available on GitHub, aiming to simplify the initial setup and configuration for developers working with Vulkan SC.
