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 Microsoft might be trying to motivate game developers to abandon the outdated DirectX 11 API this way.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).
