Windows 10: In the works: HLSL DirectX Shader Model 6.6 for developers

Brink · Nov 24, 2020

Microsoft and its partners are happy to announce the development of Shader Model 6.6, the latest advancement in HLSL capability.

Shader Model 6.6 will grant shader developers increased flexibility to enhance and expand existing rendering approaches and devise all new ones. New features include expanded atomic operations, dynamic resource binding, derivatives and samples in compute shaders, packed 8-bit computations, and wave size...

Development

Shader Model 6.6 is a work in progress.

Initial compiler implementation of these features will be submitted to the DirectXShaderCompiler GitHub repository at https://github.com/microsoft/DirectXShaderCompiler. We will continue making additional improvements there over the coming months. Hardware vendors will be implementing driver backend support in parallel. Once complete, we will formally release Shader Model 6.6 and developers can take full advantage of it.

New in D3D12 - GPU-Based Validation now available for Shader Model 6.x
In the next update to Windows, codenamed 19H1, the DirectX12 debug layer adds support for GPU-based validation (GBV) of shader model 6.x (DXIL) as well as the previously supported shader model 5.x (DXBC).

GBV is a GPU timeline validation that modifies and injects validation instructions directly into application shaders. It can provide more detailed validation than is possible using CPU validation alone. In previous Windows releases, GBV modified DXBC shaders to provide validations such as resource state tracking, out-of-bound buffer accesses, uninitialized resource and descriptor bindings, and resource promotion/decay validation. With the 19H1 release, the debug layer provides all these validations for DXIL based shaders as well.

This support is available today in the latest 19H1 builds accessible through the Windows Insider Program.

How to enable GPU-based validation for applications using DXIL shaders

No additional step is needed to enable DXIL GBV. The traditional method is extended to support DXIL based shader patching as well as DXBC:

Code:
Code:
void EnableShaderBasedValidation()  {      CComPtr<ID3D12Debug> spDebugController0;      CComPtr<ID3D12Debug1> spDebugController1;         VERIFY(D3D12GetDebugInterface(IID_PPV_ARGS(&spDebugController0)));      VERIFY(spDebugController0->QueryInterface(IID_PPV_ARGS(&spDebugController1)));      spDebugController1->SetEnableGPUBasedValidation(true);  }

Need help Identifying my DirectX Shader model

I was trying to play a game on my laptop and got an error message saying 'gpu compatible with directx 11.0 shader model 5.0 not found' and I used GPU Z to find out what my Directx version and shader model was, so I have DirectX support - 10.1 and shaders
- 12 unified, but I have no idea what '12 unified shaders' mean.

Can someone please translate this into a somewhat understandable term like shader model 2.0-5.0

I just really want to play this game!

Thanks in advance!
