The Khronos Group, an open consortium of industry-leading companies dedicated to creating advanced interoperability standards, has announced the release of Vulkan 1.4, the latest version of its cross-platform 3D graphics and compute API. Vulkan 1.4 integrates and mandates support for many proven features into its core specification, expanding the functionality that is consistently available to developers, greatly simplifying application development and deployment across multiple platforms.

The Vulkan 1.4 specification consolidates numerous previously optional extensions, features, and increased minimum hardware limits, many of which were defined in the Vulkan Roadmap 2022 and 2024 milestones and associated profiles, including:

• Streaming Transfers: Vulkan 1.4 imposes new implementation requirements to ensure portable, cross-platform applications can stream large quantities of data to a device while simultaneously rendering at full performance.
• Previously optional extensions and features critical to emerging high-performance applications are now mandatory in Vulkan 1.4, ensuring their reliable availability across multiple platforms. These include push descriptors, dynamic rendering local reads, and scalar block layouts.
• Maintenance extensions up to and including VK_KHR_maintenance6 are now part of the core Vulkan 1.4 specification.
• 8K rendering with up to eight separate render targets is now guaranteed to be supported, along with several other limit increases.
