New Vulkan Sample - VK_KHR_compute_shader_derivatives — Derivatives in compute shaders This sample demonstrates VK_KHR_compute_shader_derivatives, which enables the use of derivative instructions (like dFdx/dFdy) inside compute shaders. Traditionally, derivatives are only available in fragment […]

New Vulkan sample out: VK_KHR_shader_relaxed_extended_instruction It relaxes SPIR-V’s forward-reference rules for non-semantic instruction sets like NonSemantic.DebugPrintf, so debug-oriented SPIR-V from tooling can be accepted without changing shader behavior. Demoed with an HLSL compute […]

New Vulkan Samples - Pipeline Binary This sample shows how VK_KHR_pipeline_binary gives you explicit control over driver-produced pipeline binaries. Generate a deterministic pipeline key, capture the binary, store it with driver metadata and reload it later to avoid recompiling at runtime. A […]

The Vulkanised 2027 call for submissions has been extended two weeks, to Sunday, October 25. Vulkanised is open to everyone. Anyone can attend and anyone can submit a talk, whether you're an app or engine developer, driver implementer, tools builder, educator […] [Original post on fosstodon.org]

New Sample - Shader Quad Control This sample shows how VK_KHR_shader_quad_control lets fragment shaders share data across a 2x2 pixel quad using subgroupQuadBroadcast and the full_quads execution mode, with no shared memory and no descriptors. You get more stable derivatives for LOD selection […]

New Sample - Device Fault This sample shows how to use VK_EXT_device_fault (plus VK_EXT_device_address_binding_report) to pull real diagnostic data out of a GPU crash: vendor fault descriptions, the exact faulting memory address, and a live log of every buffer's bind/unbind range so you can […]

New Sample – Descriptor Heap This sample renders textured cubes to demonstrate VK_EXT_descriptor_heap, which replaces the traditional descriptor set and pool workflow with a memory-centric one where descriptor data is written directly into heap memory. It shows new heap-binding functions […]

New Sample - Swapchain Present Timing The sample renders a circle moving linearly across the viewport, which is a good visual test for detecting micro-stutters and verifying smooth presentation. It queries past presentation timing information and uses the last known display time along with the […]

New Sample - VK_EXT_layer_settings This sample demonstrates how to use VK_EXT_layer_settings to configure Vulkan layers (in particular VK_LAYER_KHRONOS_validation) directly from your application. Instead of relying on environment variables or JSON files, you can enable features like Best […]
