What does dx12 mean?

dx12 refers to DirectX 12, a multimedia programming interface created by Microsoft.

Microsoft officially released a new generation of API DirectX 12 (DX12) at GDC 2014. Although it is not a replica of the AMD Mantle API as claimed by foreign media two days ago, its specific details have not been announced. However, we can still see that DirectX 12 contains some new things.

Microsoft will officially bring DirectX 12 (hereinafter referred to as DX12) on the Win10 system, and DX12 will only support Windows10. It seems that Microsoft is working hard to promote Win10. However, Microsoft is more confident this time than just allowing XP to support DX9, because DX12 is much more popular than DX9. The world’s first game to support DirectX 12 is Ashes of the Singularity.

New Features

The most important change in DX12 is the lower-level API. This is very similar to AMD Mantle, which goes deeper than ever on the hardware abstraction layer. It can reduce the overload of CPU and GPU at the same time.

Specifically includes: applications can track the GPU pipeline, control resource state transitions (such as from rendering targets to textures), control resource renaming, fewer API and driver tracking, predictable attributes, etc.

In addition, DX12 greatly improves multi-threading efficiency and can fully utilize the potential of multi-threaded hardware. DX11 is severely limited by CPU performance in this regard, mainly because it cannot effectively utilize multiple cores.

Microsoft claims that Microsoft's utilization of multi-core CPUs increases almost perfectly linearly, which means that four cores can be close to four times that of a single core.

In addition, there are improvements in the rendering pipeline, rendering features, resource management, command lists and bindings, descriptor jumping, etc., because they are mainly about development and are relatively obscure, so I won’t go into them here. Too much.
