The release also adds KHR_opacity_micromap support for exposing DXR 1.2 when available, plus Shader Model 6.9 support. It brings more NVIDIA NVAPI intrinsics to the DXIL-SPIRV code, exposes AgilitySDK 619 features, and enables view instancing by default. Hans-Kristian Arntzen calls this the last stable release before a big change in version 3.2. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What new features does VKD3D-Proton 3.1 add? VKD3D-Proton 3.1 adds descriptor heap support through VK_EXT_descriptor_heap, though it is not enabled by default due to driver quality concerns. It also adds KHR_opacity_micromap support to expose DXR 1.2 where supported, Shader Model 6.9 support, more NVIDIA NVAPI intrinsics in the DXIL-SPIRV code, AgilitySDK 619 feature exposure, and view instancing enabled by default. _Track vkd3d-proton releases on daily.dev before upgrading your Direct3D 12 on Linux setup._ ### Why isn't descriptor heap support enabled by default in VKD3D-Proton 3.1? Descriptor heap support via VK_EXT_descriptor_heap ships in VKD3D-Proton 3.1 but is not turned on by default because of driver quality concerns. It is included in the release for testing while the ecosystem matures before becoming a default feature. _Developers weighing Vulkan extension readiness can follow driver maturity updates on daily.dev._ ### Is VKD3D-Proton 3.2 going to be a major release? Yes, developer Hans-Kristian Arntzen describes VKD3D-Proton 3.2 as bringing a ton of important changes, calling version 3.1 the last stable release before 'plunging into uncharted territory'. This signals significant architectural or feature shifts coming after 3.1. _Keep up with vkd3d-proton's roadmap on daily.dev before planning your next Linux gaming stack update._ ## Similar posts on daily.dev - [VKD3D-Proton 3.0.1 Brings More Improvements For Direct3D 12 On Vulkan](https://daily.dev/posts/vkd3d-proton-3-0-1-brings-more-improvements-for-direct3d-12-on-vulkan-bft5rvht5) · Phoronix · 0 upvotes · 0 comments - [DXVK 3.0 Released With DXBC-SPIRV For Shader Compilation, Descriptor Heaps By Default](https://daily.dev/posts/dxvk-3-0-released-with-dxbc-spirv-for-shader-compilation-descriptor-heaps-by-default-ts3ntd8im) · Phoronix · 0 upvotes · 0 comments - [DXVK 3.1 Released With DXGI Incremental Presentation, D3D11 Buffer Render Targets](https://daily.dev/posts/dxvk-3-1-released-with-dxgi-incremental-presentation-d3d11-buffer-render-targets-k3fcuyw3e) · Phoronix · 0 upvotes · 0 comments --- Tags: [#gaming](https://daily.dev/tags/gaming), [#vulkan](https://daily.dev/tags/vulkan) [View this post on daily.dev](https://daily.dev/posts/vkd3d-proton-3-1-released-with-new-features-ahead-of-big-v3-2-release-9zwbxqoyd) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"VKD3D-Proton 3.1 Released With New Features Ahead Of Big v3.2 Release","url":"https://daily.dev/posts/vkd3d-proton-3-1-released-with-new-features-ahead-of-big-v3-2-release-9zwbxqoyd","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/vkd3d-proton-3-1-released-with-new-features-ahead-of-big-v3-2-release-9zwbxqoyd"},"datePublished":"2026-10-28T10:36:13.912Z","dateModified":"2026-10-28T15:03:23.452Z","description":"VKD3D-Proton 3.1 is out, adding descriptor heap support via VK_EXT_descriptor_heap, though it's not enabled by default due to driver quality concerns.
