Microsoft DX12 Tier 12_2, features and news

Several updates have been launched with degree 12_2, amongst which we spotlight DXR 1.1, Shader Model 6.5, Variable Rate Shading tier-2, amongst different. In precept, the one succesful graphics playing cards are these primarily based on Turing, that’s, the sequence GeForce RTX 20. However, Microsoft has introduced that RDNA2 too might be appropriate with 12_2.

The significance of function degree updates in Microsoft DX12

You might surprise what’s a function degree or degree of features, so we are going to begin from the purpose the place all GPUs aren’t the identical, both due to their traits or due to their sorts of functionalities. DirectX 12 supplies plenty of functionalities which might be assured by any GPU with a DX12 controller.

This DirectX 12 supplies methods for that differentiation between GPUs to be managed by purposes. A operate degree or level-feature is the identify that used to explain a set of graphics card capabilities; it’s a property of the GPU.

Therefore, video games and purposes should be programmed to detect what ranges of features can be found within the system with the intention to use a set of features. These Function ranges permit optimization of software code and foster the adoption of latest {hardware} capabilities.

Basically, they’re wanted for purposes to make sense of enhancements of {hardware} that GPUs obtain over time. In this fashion, the level-feature of 12_1 collects all of the capabilities of 12_0, however provides some extra; so on. As graphics playing cards enhance, software or sport builders have a a lot simpler job.

What’s New in DX12 Tier 12_2

So, Microsoft has launched DX12 Tier 12_2 to optimize four key features which might be associated to video video games:

There is little question that Ray Tracing is right here to remain, so optimization is essential. Keep in thoughts that the following GPUs RDNA2 AMD will assist Ray Tracing, which is why Microsoft has introduced that this technology of graphics playing cards will obtain assist 12_2.

Updates launched by Microsoft in DX12 Tier 12_2 are associated to DXR 1.1, Shader Model 6.5, Variable Rate Shading tier-2, Resource Binding tier-3, Tiled Resources tier-3, Conservative Rasterization tier-3, Root Signature tier-1.1, Write Buffer Immediate Support Flags and, amongst others, the GPU enlargement Virtual Address Bits.

This degree of features requires a WDDM 2.zero driver and a appropriate graphics card. Right now, solely the technology of Turing (Series 20) is appropriate with this controller, though on the finish of 2020 it would stop to be the one privileged one.

As will occur with RDNA2, the following technology of graphics playing cards NVIDIA Ampere DirectX 12 Tier 2_2 could also be supported, though Microsoft has not talked about something about it. What he has acknowledged categorically is that we will solely use operate degree 12_2 with DirectX 12.
