Intel’s driver team has published a new graphics driver for all recent GPUs (Intel 6th, 7th and 8th Gen processors) on Windows 10. This new driver (version 25.20.100.6323) brings support for Windows 10 October 2018 Update (version 1809 with WDDM 2.5) and HDR for embedded laptop panels. Hardware support now included up to Vulkan 1.1.83, OpenCL 2.1 and OpenGL 4.5. Complete details are in the Intel Release Notes PDF.

The first GPUs from the Turing architecture have arrived with lots of new features. Extensions have been added to both Vulkan and OpenGL to give developers access to these new features. The various Khronos Registries and Repositories have been updated to include the specifications and tools for the new extensions. The Vulkan and OpenGL extensions are enumerated on the NVIDIA website to provide developers access to these new features.

Khronos has released a provisional Vulkan Memory Model Specification that includes extensions for Vulkan, SPIR-V, and GLSL and gives Vulkan developers additional control over how their shaders synchronize access to should cooperate safely over memory operations in a parallel execution environment. In tandem with the extension specification, Khronos has released memory model extension conformance tests to enable implementers to do early tests on their shader compilers to ensure that the specified memory synchronization is implemented correctly. The memory model will have an Alloy description of the extension functionality to enable formal modeling and experimentation.

Forsaken Remastered was just updated with Vulkan support! If you're on Linux, you're probably hitting 60fps with the existing OpenGL renderer, but it's good to be future proof. If you're on a Mac, though, you definitely want to switch. On my MacBook, the framerate goes from around 15 to a solid 60! On macOS, Vulkan support is supplied by MoltenVK, which we now ship with the game. It should work on any Mac that supports Apple's Metal API, which MoltenVK uses to make Vulkan work. You can change from OpenGL to Vulkan in-game in the "Video" options menu.

AMD released Vulkan Memory Allocator 1.0 (VMA) back in July last year, but haven't posted much since. Version 2.0 of the library was released back in March 2018 and now version 2.1 has been released. This post gives an overview of the changes and version 2.1 is all about.

Some members of the Vulkan working group are developing a multi-vendor EXT extension for transform feedback with the primary goal of satisfying the needs of the DXVK, vkd3d and ANGLE translation layers. The Vulkan working group does not plan to promote this functionality as a KHR extension or as core functionality because it believes there are better, more forward-looking ways of processing and capturing vertex data with the GPU. The multi-vendor EXT extension should be available soon and is likely to be implemented on those platforms where DXVK, vkd3d and ANGLE translation is required.

This mini-tutorial presents a simple use-case the new VK_EXT_conditional_rendering extension. With the new VK_EXT_conditional_rendering extension, Vulkan gains the possibility to execute certain rendering and dispatch commands conditionally, based on values stored in a dedicated buffer. So instead of having to rebuild command buffers if the visibility of objects change it’s now to possible to just change a single buffer value and the to control if the rendering commands for that object are executed without the need to touch any command buffers.

MoltenVK 1.0.20 is out as the latest feature update to this Vulkan-over-Metal layer. With the MoltenVK 1.0.20 release there is support for several new extensions including VK_KHR_maintenance1, VK_KHR_shader_draw_parameters, VK_KHR_get_physical_device_properties2, and VK_KHR_push_descriptor. MoltenVK 1.0.20 also adds the ability to track and access supported/enabled extensions and has re-based its SPIRV-Cross code against upstream.

Vulkan multi-GPU support was announced by Khronos in March 2017 but it wasn’t until Vulkan 1.1 was released in March this year that explicit multi-GPU support was added to the API. Now the first AAA game to support multi-GPU in Vulkan has been released - the action-packed Strange Brigade for PC.

AMD's GPUOpen group has released their first beta of the Vulkan Memory Allocator 2.1 release after "many months of development" and as such comes with many new features. VulkanMemoryAllocator is the open-source AMD effort to provide an easy-to-use and integrate Vulkan memory allocation library to ease the process of bringing up new Vulkan code.

Intel’s driver team has published a new graphics driver for all recent GPUs (Intel 6th, 7th and 8th Gen processors) on Windows 10. This driver version exposes Vulkan 1.1.82, and continues to support OpenGL 4.5, exposing the same OpenGL support as v4944 (245 OpenGL extensions). Direct download from Intel is here.

Stardock Entertainment announced the extension of their technology and gaming partnership with AMD. As part of the ongoing partnership, Stardock will optimize the upcoming Star Control: Origins for AMD technologies including AMD Ryzen processors and Radeon FreeSync 2 technology, as well as update the game post-launch with support for the Vulkan™ Graphics API.

In March, AMD announced the V-EZ Vulkan wrapper, with an aim to make Vulkan development easier. A few days ago it appears that AMD has moved the V-EZ wrapper to open source: "V-EZ is an open source, cross-platform (Windows and Linux) wrapper intended to alleviate the inherent complexity and application responsibility of using the Vulkan API. V-EZ attempts to bridge the gap between traditional graphics APIs and Vulkan by providing similar semantics to Vulkan while lowering the barrier to entry and providing an easier to use API."
