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

Khronos Streamlines Development and Deployment of GPU-Accelerated Applications with Vulkan 1.4

The Vulkan Working Group has released two important updates to the API and ecosystem: an entirely new Descriptor system and the Vulkan Roadmap 2026 Milestone.

This milestone raises the baseline feature support of Vulkan implementations as with prior milestones. In addition, this milestone makes guarantees about swapchain and presentation support for implementations.

The new VK_EXT_descriptor_heap extension represents a complete overhaul of the current Vulkan descriptor system, providing direct access to descriptor memory while preserving compatibility with legacy descriptor sets and other APIs.

This document outlines a proposal to make the management of descriptor memory more explicit, allowing descriptors to be present in buffer memory, allowing the data and memory to be managed alongside other buffer objects.

Khronos has released finalized extensions, collectively called ‘Vulkan Video’, for seamlessly integrating hardware-accelerated video compression and decompression into the Vulkan API. This API incorporates industry feedback and exposes core decode Vulkan Video functionality to provide fully accelerated H.264 and H.265 decode.

Vulkan Video adheres to the Vulkan philosophy of providing applications flexible, fine-grained control over scheduling, synchronization, and memory allocation. By leveraging the existing Vulkan API framework, the Vulkan Video extensions enable efficient, low-latency, low-overhead use of processing resources for accelerated video processing.

With the release of Vulkan 1.3.274, Khronos has finalized the extensions to enable encoding of H.264 and H.265 video streams.

Khronos Releases AV1 Decode in Vulkan Video with SDK Support for H.264/H.265 Encode

The newly released VK_KHR_synchronization2 extension brings extensive improvements to Vulkan queue submission, events, and pipeline barriers to significantly improve API usability for developers.

The goal of this article is to help developers easily understand and not be intimidated or confused by one of the toughest aspects of Vulkan: Synchronization.

See this chapter in the Vulkan Guide for an overview of the latest Vulkan synchronization capabilities

See the details of VK_KHR_synchronization2 in the Vulkan specification

Demonstrates the use of the reworked synchronization api introduced with VK_KHR_synchronization2. This sample uses the new extension to streamline memory barriers used for compute and graphics work submissions.

Khronos® has released the final versions of the set of Vulkan®, GLSL and SPIR-V extension specifications that seamlessly integrate ray tracing into the existing Vulkan framework.

For an overview of Ray Tracing in Vulkan, check out this chapter in the Vulkan Guide

Start with the Ray Traversal and Ray Tracing sections of the Vulkan Spec for more details

Render a basic scene using the official cross-vendor ray tracing extension. Shows how to setup all data structures required for ray tracing

The new timeline semaphore synchronization API defines a primitive containing a superset of both the original VkSemaphore and VkFence primitives while simultaneously eliminating many of the most painful limitations of the previous APIs

See detials for Timeline Semaphore in the Vulkan Specification

Demonstrates various use cases which are enabled with timeline semaphores. The sample implements "Game of Life" using out-of-order signal and wait, multiple waits on same semaphore in different queues, waiting and signalling semaphore on host.

The VK_KHR_fragment_shading_rate extension provides a new, flexible technique to control the fragment shading rate, enabling developers to perform shading at a lower resolution than the render targets.

See detials for VK_KHR_fragment_shading_rate in the Vulkan Specification

Uses a special framebuffer attachment to control fragment shading rates for different framebuffer regions. This allows explicit control over the number of fragment shader invocations for each pixel covered by a fragment

Android is enabling a host of useful new Vulkan extensions for mobile. These new extensions are set to improve the state of graphics APIs for modern applications, enabling new use cases and changing how developers can design graphics renderers going forward.

See details for Descriptor Indexing in the Vulkan Specification

Demonstrates how to use descriptor indexing to enable update-after-bind and non-dynamically uniform indexing of descriptors
