Several updates have been introduced at the 12_2 level, which we highlight DXR 1.1, Shader Model 6.5, Flexible Tate Shading tier-2, among other things. Basically, the only graphics cards that are capable are those based on Turing, that is, series IGeForce RTX 20. However, Microsoft has announced that RDNA2 and will go hand in hand at 12_2.
Importance of feature level updates on Microsoft DX12
You may wonder what is the level of feature or level of activity, so we will start from a place where all GPUs are different, either because of their features or because of their performance types. DirectX 12 provides several functionality guaranteed by any GPU with DX12 controller.
This DirectX 12 provides ways to differentiate between GPUs for manageable applications. Performance level or feature-level that’s the name is used to describe a set of graphics card skills; it is a GPU asset.
Therefore, games and applications should be included in the system to determine what levels of activity are available in the system in order to use a set of activities. These Performance standards allow for efficient operation of the input code and promotes the adoption of new hardware skills.
Basically, they are what apps need is to make sense of development
What’s New in DX12 Tier 12_2
Therefore, Microsoft has released DX12 Tier 12_2 to enhance 4 video-related features:
There is no doubt that Ray Tracing is here to stay, so good use is essential. Remember the following GPUs RDNA2 AMD will support Ray Tracing, which is why Microsoft has announced that this generation of graphics cards you will receive support
Updates introduced by Microsoft on DX12 Tier 12_2 are related DXR 1.1, Shader Model 6.5, Flexible Tate Shading tier-2, Resource Binding tier-3 resources, Integrated Resources 3, Conservative Rasterization tier-3, Root Signature tier-1.1, Write Buffer Instant Flags w, entre otras, la expansión GPU Virtual address Bits.
This standard requires a WDDM 2.0 driver and a matching graphics card. Currently, the generation of Exercise (Series 20) is in line with this rule, although by the end of 2020 it will end up being the only lucky one.
As will happen with RDNA2, the next generation of graphics cards NVIDIA Ampere DirectX 12 Tier 2_2 can be supported, even if Microsoft does not say anything about it. What he said in terms of categories is we can only use job level 12_2 with DirectX 12.
