DirectX 12 Agility SDK Downloads

• Updates DirectSR preview built-in upscaler variant from FSR2 to FSR3.1

• Enabled R9G9B9E5_SHAREDEXP format for Render Target and Unordered Access Views (device support still needs to be queried)
• Minor state object validation fixes related to dxil defined subobjects and collections

See here for more info about the release.

• Work Graphs
• Shader Model 6.8
  • Work Graphs support
  • Start Vertex/Instance Location
  • Wave Size Range
  • Expanded Comparison Sampling
• GPU Upload Heaps (requires future OS)
• Incrementing Constant in ExecuteIndirect
• Generic Programs in State objects

• Minor updates for .3:
  • Honor root signature associations added to export in collections when the export is imported into generic program in an executable state object.
  • Propagate root signatures to exports that have bindings and no root signatures within the scope of a generic program, like what happens with PSOs
  • Other generic programs related bug fixes, additional validation and optimizations.
  • For state objects, minor fixes to subobject association logic in edge cases involving collections to more precisely match spec wording.

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

• Incrementing Constant in ExecuteIndirect
• Generic Programs in State objects

• 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

• 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

• 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.

• 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

• 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.

• 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

• Header build fix
• Fixes bug preventing enhanced barriers enablement

New minor features:

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

• 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

New features:

• Relaxed buffer/texture copy alignment
• Support for copying between different dimensions of textures
• Delayed input layout and vertex buffer alignment validation
• Negative height viewports flip y-axis intepretation
• 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.  

Shader Model 6.6

• Mesh nodes in work graphs. See the blog for more info.
• Continues to include DirectSR from the recent 1.714.0 preview.
