Microsoft Win10 20H1 version DX12 function is greatly promoted, RTX graphics card cost performance

For Microsoft, they announced that the DX12 feature in the Windows 10 20H1 version will greatly upgrade, bring new DXR 1.1 light chasing, grid rendering and sampling feedback, etc. 3D graphics to draw. In this DX12 function, DirectX Raytracing Tier 1.1 adds additional shader Shader in the existing light tracking line status object PipeLine State Object, which allows the developer to call the shader containing the light tracking function, this shader Any phase of the light tracking operation can occur, supporting the indirect execution of light tracking, and introduces inline light tracking, managing the light travel algorithm and shader. This is equivalent to a higher level and more effective game on the basis of DXR 1.0. DirectX Raytracing Tier 1.1 has also received more popular game support. So far, more than 30 upcoming and published games have been compatible with DXR 1.1 performance, such as NVIDIA GeForce RTX announced fully supporting DXR 1.1 new special effects. In addition to the DXR light chasing technology upgrade, Microsoft also introduces mesh shader in the latest version of DX12, which is the next generation of GPU geometric processing features, replacing the current input assembler, vertex renderer, boat renderer, surface Segmentation, domain renderer, geometric renderer, etc. Microsoft said that introducing a grid renderer is mainly to improve the flexibility and performance of geometric rendering lines, allowing game developers to render more complex scenes without sacrificing rates. In addition, the sampler feedback Sampler feedback is the new feature obtained after this DirectX 12 Ultimate update. Its main role is to record the texture area access to the sampled operation, and in the texture space shadow Texture-Space Shading, Shadow multiplex shading reuse, Texture Texture Streaming applied. To know, sampler feedback can help the development team more effectively avoid redundancy, enhance the utilization of memory on the material, and reduce unnecessary calculations, thereby implementing the effect of optimizing the game. Microsoft also said that next-generation games using DX12 Ultimate features will continue to run on non-DX12 Ultimate hardware, from this move, Microsoft unified graphics platforms in PC and Xbox Series X. Therefore, the PC will benefit from a large number of emerging DX12 Ultimate new function hardware. For NV and AMD, it is expressed that it will fully support DirectX 12 Ultimate, such as the upcoming AMD RDNA 2 game architecture, fully supporting DirectX 12 Ultimate all new features, and for ordinary players, geforce is being used. RTX graphics cards directly become free tickets for experience the next-wave new game screen, no need to have additional input to hardware. The GEFORCE RTX Series graphics card costs have been raised again. Read more
