Changelog

Version 1.0.13-preview

New features:

• Variable Rate Shading (VRS) Tier 2 support
• Wide wave size emulation support
• Redesigned barriers, more likely to catch app bugs and with higher throughput
• Work graphs tier 1.1: Mesh nodes

Bug fixes:

• Fix incompatibility between new WARP and old D3D12SDKLayers
• Fixes for work graphs where record reads are done under non-uniform control flow

Version 1.0.12

New features:

• Now including arm64 binaries

Bug fixes:

• Fix mesh shaders on Win11 retail D3D12
• Fix accessing static const arrays in generic programs
• Fix arm64 instruction encoding which could cause random crashes in shader execution
• Fix state objects exporting the same non-library shader with multiple names/aliases
• Fix handling of zeroing used by lifetime markers on older shader models
• Fix handling of lifetime markers in node shaders
• Handle a null global root signature in a work graph
• Fix mesh -> PS linkage for primitive outputs that were not marked nointerpolate in the PS input
• Fix back-to-back DispatchGraph without a barrier to correctly share the backing memory
