Microsoft: DirectX 12_2, with new features like DXR and Mesh shaders, will only work with DirectX 12, pushing developers to transition from DX11.
Microsoft's latest blog post reveals that the new DirectX version, "12_2," will bring a significant expansion of features to the company's established API.
DirectX raytracing – a unified ray tracing pipeline (DXR);
Mesh shaders – allows more flexible geometry calculation modification operations;
Variable rate shading – a technology to save graphics card resources when rendering peripheral objects and areas;
Sampler feedback – a function for collecting and recording information about texture sampling and their location;
The more interesting and quite intriguing change is that DirectX 12_2 will only be compatible with DirectX 12. Microsoft might be trying to motivate game developers to abandon the outdated DirectX 11 API this way.
"D3D_FEATURE_LEVEL_12_2" is already available through the Windows early access program (SDK (software development kit) and Windows build version 20170, or a newer build).
You can find a complete overview of the new technology via this link in the official Microsoft blog (English knowledge required).
