Vulkan 1.1 Released

The Khronos Group has released the Vulkan 1.1 and SPIR-V 1.3 specifications.

Version 1.1 expands Vulkan's core functionality with developer-requested features, such as subgroup operations, while integrating a wide range of extensions from Vulkan 1.0. Khronos will also release full Vulkan 1.1 conformance tests into open source and AMD, Arm, Imagination, Intel Corporation, NVIDIA and Qualcomm have implemented conformant Vulkan 1.1 drivers.

Vulkan 1.1 will drive industry momentum for this new-generation, cross-platform standard for explicit control over GPU acceleration. Vulkan now ships natively on almost all GPU-enabled platforms, including Windows 7, 8.X, 10, Android 7.0+ and Linux, plus Khronos recently announced open source tools to enable Vulkan 1.0 applications to be ported to macOS and iOS. Vulkan has widespread support in games engines including Unreal, Unity, Source 2 from Valve, id Tech, CroTeam's Serious Engine, CryEngine, and Xenko. Vulkan is being used in over 30 games on diverse desktop and mobile platforms, including Doom, Quake, Roblox, The Talos Principle, Dota 2, and is the exclusive API used in AAA titles such as Wolfenstein II and Doom VFR.

New functionality in Vulkan 1.1 includes Subgroup Operations that enable highly-efficient sharing and manipulation of data between multiple tasks running in parallel on a GPU. Vulkan 1.1 also enables applications to perform rendering and display operations using resources that they cannot access or copy - for secure playback and display of protected multimedia content.

In addition, a wide range of Vulkan 1.0 extensions have been integrated, bringing proven functionality into core Vulkan 1.1, including: simultaneous rendering of multiple image views, use of multiple GPUs in a single system, and cross-process API interoperability for advanced rendering and compositing operations often used in demanding applications such as Virtual Reality. These core functionalities also include advanced compute with 16-bit memory access, and support for HLSL memory layouts, and display, processing and compositing of video streams, through direct sampling of YCbCr color formatted textures produced by many video codecs.

Integral to the release of Vulkan 1.1 is the new SPIR-V 1.3 specification that expands the capabilities of the Vulkan shader intermediate representation to support subgroup operations and enable compiler optimizations.
