DirectX 12 Agility SDK Downloads

Welcome to the DirectX 12 Agility SDK landing page where you’ll find links to Agility SDKs and other helpful info.

Check out our Announcement blog and Game Stack Live talk.

We also have a Getting Started Guide with detailed info for developers who want to integrate Agility SDK support into their engine.

Visit the DirectX Landing Page for more resources for DirectX developers.

Latest Agility SDK
SDK Package D3D12SDKVersion Release Date New features
SDK 1.613.2 613 3/29/2024 Same as 1.613.1 with minor updates summarized at the bottom:

  • Minor updates for .2:
    • Close validation hole: Prevent use of features in incompatible state object types, such as defining generic program components (like rast state) in a raytracing pipeline.
    • Debug layer fixes around its lifetime management of program identifiers (e.g. the handles for the new generic programs)
    • ExecuteIndirect validation was too strict: buffer size only needs to be big enough for the number of commands * stride, minus the unused space at end of last command

See here for more info about the main release, 1.613.

Older Agility SDKs
SDK Package D3D12SDKVersion Release Date New features
SDK 1.613.1 613 3/19/2024 Same as 1.613.0 with minor updates summarized at the bottom:

  • Minor updates for .1:
    • In d3d12.h: missing const on input pointer members: D3D12_NODE_CPU_INPUT.pRecords and D3D12_MULTI_NODE_CPU_INPUT.pNodeInputs
    • Debug layer validation fixes for D3D12_DISPATCH_MODE_MULTI_NODE_CPU_INPUT
    • Some missing validation for generic programs (to line up with existing PSO path)
    • Allow generic programs or work graphs only in executable state objects, not collections

See here for more info about the main release, 1.613.
SDK 1.613.0 613 3/11/2024

See here for more info about this release
SDK 1.611.2 611 11/16/2023
  • Fix crash in D3D12SDKLayers creating resource with initial enhanced layout when legacy state validation forced on.
  • Fix std::bad_optional_access exception in D3D12SDKLayers and fixup partially promoted state.
SDK 1.611.1 611 10/19/2023
  • Added support for AV1 Encode
  • Make pContext mutable in ID3D12InfoQueue1::RegisterMessageCallback.
  • Legacy transitions into/out-of UAV state includes: D3D12_BARRIER_SYNC_BUILD_RAYTRACING_ACCELERATION_STRUCTURE D3D12_BARRIER_SYNC_EMIT_RAYTRACING_ACCELERATION_STRUCTURE_POSTBUILD_INFO D3D12_BARRIER_SYNC_COPY_RAYTRACING_ACCELERATION_STRUCTURE This only applies to buffer barriers.
  • Fix enhanced barrier SYNC_DRAW being incompatible with ACCESS_RENDER_TARGET
  • Improve enhanced barrier validation for raytracing acceleration data structures
SDK 1.610.4 610 06/26/2023
  • Fix some aliasing barrier regressions on drivers supporting enhanced barriers.
    • Full cache flush supporting aliasing barrier on stencil resources
    • Use a global barrier rather than a buffer or texture barrier when translating non-null aliasing barriers. The global barrier guarantees a cache flush, which is needed when aliased resources share memory but do not share the same VA space.
SDK 1.608.3 608 03/02/2023 Validation fixes:

  • Fixed state corruption causing incorrect programmable sample positions validation during ExecuteCommandList
  • Address incorrect Enhanced Barriers simultaneous-access validation
  • Fix incorrect Enhanced Barriers sync/access validation
  • Add missing string conversion for D3D_BARRIER_SYNC_CLEAR_UNORDERED_ACCESS_VIEW
SDK 1.608.2 608 01/03/2023
  • Header build fix
  • Fixes bug preventing enhanced barriers enablement
SDK 1.608.0 608 11/18/2022 Enhanced Barriers

New minor features:

  • Independent Front/Back Stencil Refs and Masks
  • Triangle fan
  • Dynamic Pipeline State: Depth Bias, IB Strip Cut

See here for more information
SDK 1.602.4 602 6/21/2022 Bugfixes

  • Fixes bug in GBV to skip bounds checks on static descriptors already bounds-checked on the CPU timeline
  • Fix false Object Deleted While Still in Use errors from debug layer
  • Fix deadlock in debug layer while validating placed resource virtual addresses
  • Fix crash in ResolveQueryData due to race condition
SDK 1.602.0 602 4/27/2022 See blog post for more detail

New features:

  • Relaxed buffer/texture copy alignment
  • Support for copying between different dimensions of textures
  • Delayed input layout and vertex buffer alignment validation

  • Alpha/InvAlpha blend factors

Bugfixes

  • Fixes a crash using GBV with shader patch mode TRACKING_ONLY. 
  • Fixes false debug validation output resulting from depth slice state being confused with depth slice state. 
  • Fixes a bug causing promoted COPY_DEST to not decay back to COMMON. 
  • Report live objects when encountering device removed from a kernel memory failure.
