StructureByteStride of UAV in create_graphics_buffer and Inference.compute mismatch

[NealLou]

I have noticed an inconsistency in the stride values of m_GBuffer used in the following files:

TextureSetNeuralCompressionSample/sdk/src/render_pipeline/dino_renderer.cpp

Line 170 in 2ce5bfb

m_GBuffer = graphics::resources::create_graphics_buffer(m_Device, numPixels * sizeof(uint16_t) * numChannels, sizeof(uint16_t), GraphicsBufferType::Default);

The elementSize (stride) in create_graphics_buffer is written as sizeof(uint16_t) = 2 bytes.

TextureSetNeuralCompressionSample/shaders/GBuffer/Textures/Inference.compute

Line 44 in 2ce5bfb

RWStructuredBuffer<uint4> _OutputBufferRW: register(OUTPUT_BUFFER_BINDING);

But the format used for m_GBuffer as outputBuffer in Inference shader is uint4, and its stride is 16 bytes.

https://microsoft.github.io/DirectX-Specs/d3d/ResourceBinding.html#unordered-access-view Spec requires StructureByteStride for UAV.

The stride values in those places are different, which might lead to unexpected behavior or quality issues.
Could you please verify if this is intentional or if it needs to be corrected?

How about using RWByteAddressBuffer instead, like Cooperative Vector does?

Thank you for your attention to this matter.
