For Microsoft, they announced that the dx12 function in Windows 10 20h1 will be greatly upgraded, bringing new DXR 1.1 light tracing, grid rendering, sampling feedback and other new functions, and 3D graphics card will be shuffled.

This DX12 feature DirectX Raytracing Tier 1.1 added additional shader Shader, to existing ray tracing pipeline status objectsThis allows developers to call shaders with ray tracing function, which can appear at any stage of ray tracing operation, support indirect execution of ray tracing, and introduce inline ray tracing to manage ray traversal algorithm and shaders.This is equivalent to a set of higher-order and more effective playing methods based on DXR 1.0

DirectX raytracing tier 1.1 also has more extensive game support. So far, more than 30 upcoming and released games have announced compatibility with DXR 1.1 performance. For example, NVIDIA geforce RTX has announced full support for DXR 1.1 new effects.

in addition to DXR optical tracking technology upgrade, microsoft will introduce mesh rendering (mesh shader) in the latest edition of the DX12, which is the next generation of GPU geometry processing features, replacing the current input assembler, vertex renderer, ship renderer, surface subdivision, domain renderer, geometric renderer, etc.


Microsoft said that the introduction of mesh renderer is mainly to improve the flexibility and performance of the geometric rendering pipeline, which can allow game developers to add geometric details without sacrificing speed to render more complex scenes.

In addition,The sampler feedback sampler feedback is a new function obtained after the DirectX 12 ultimate update. Its main function is to record the texture area visited by the sampling operation, and apply it in texture space shading, shadow multiplexing shading reuse, texture streaming.

It is important to know that sampler feedback can help the development team avoid redundancy more effectively, improve the utilization of memory for materials, and reduce unnecessary calculation, so as to achieve the effect of optimizing the game.

Microsoft also said that the next generation of games using dx12 ultimate will continue to run on non dx12 ultimate hardware. From this move, Microsoft has unified the graphics platform on PC and Xbox series X. Therefore, PC will benefit from a large number of emerging dx12 ultimate new functional hardware.

For NV and AMD, they both said that they would provide full support for DirectX 12 ultimate. For example, the upcoming amd rDNA 2 game architecture fully supports all the new features of DirectX 12 ultimate,For ordinary players, the geforce RTX card is a free ticket to experience the next wave of new game screen upgrades without any additional investment in hardware.

The price performance ratio of geforce RTX Series graphics card has been improved again.
