But now,A foreign god has extracted DirectX 12 from the new version of Win10. It is compatible with the Win7/Win8.1 system and the GTX6/7/9 Series, AMD HD7000/R200 series graphics card, and the performance of the game will increase by more than 60%!
DirectX 12 software characteristics
1. New features
The most important change of DirectX12 is the bottom -level API. This is very similar to AMD MANTLE. It goes deeper on the hardware abstract layer than ever, and can reduce the overload of CPU and GPUs at the same time.
Specifically include: the application can track the GPU assembly line, control the status conversion of the resource status (such as from rendering targets to texture), control the renames of resource renames, less API and driver tracking, predictive attributes, and so on.
In addition, DirectX 12 greatly improves multi -threaded efficiency, and can give full play to the potential of multi -threaded hardware. DX11 is severely restricted by the performance of the CPU in this regard, mainly because the multi -core cannot be effectively used.
Microsoft claims that Microsoft's utilization of multi -core CPU has almost perfected and linear, that is to say, quad -core can be closer to the single core four times.
In addition, DirectX12 also has improvements in rendering assembly lines, rendering, resource management, command lists and binding, descriptive jumping, etc., because it is mainly about development, and it is relatively deep.
2. Hardware support
NVIDIA confirmed that all the models of Cairple, Fermi, and Maxwell all support DX12, that is, the models since the GeForce 200 series, DX11 can do it.
AMD confirmed that all graphics cards in the GCN architecture support DirectX 12, that is, Radeon HD 7000, Radeon R200 series.
Intel confirmed that the fourth -generation Haswell can support DirectX 12, but in fact only two high -end models: GT3 IRIS 5100, GT3E IRIS Pro 5200.
I don't know if they are 100% API support or only the support of the characteristic set, but at least one thing is that the DX12 does not require new hardware to achieve it. Essence
3. Qualcomm and Mobile
The reason why Qualcomm is listed alone is that this is the first time it cooperates with Microsoft DX, and it is also the first time Microsoft DX officially faces the field of mobile.
According to Qualcomm, DX12 can greatly improve energy efficiency, improve mobile device performance, and is very good in terms of scalability and transplantability.
4. Xbox One
AMD has just said that DirectX 12 will fully guide Xbox One, while Microsoft said that they only spent four people's monthly energy and turned the core rendering engine of the Xbox One from DX11.1 to DX12.
Prior to this, some of the characteristics that belonged to DX12 exist in Xbox One (it seems that it has been planned for a long time), and others have been transplanted.
In addition, EPIC Games also stated that they are working closely with Microsoft and NVIDIA, so that the newly released Unreal Engine 4 perfectly supports DX12 -not mentioned AMD. It seems that the unreal 4 game will tend to N card.

DirectX 12 Common questions
1. Win10 to open the DX12 method? How to see if your graphics card supports DX12?
1. In the desktop of the Windows 10 system, right -click the start button in the lower left corner of the desktop and select the "Run" menu item in the pop -up menu.
2, or on the Windows 10 system desktop, press the shortcut key Win+R combination key on the keyboard at the same time
3. At this time, you can open the running window of the Windows 10 system. Enter the DXDIAG command in the running dialog box, and then click the "OK" button
4. At this time, the DirectX diagnostic tool will be opened. At the same time, the software will automatically scan the system. The lower left corner will display the process of the diagnosis
5. After the diagnosis is completed, we click the "Display" tab above
6. You can see some information of the graphics card here. We check the functional level and driver model in the lower right corner. If your graphics card supports DX12, there will be 12 in its functional level. The driver model below is WDDM2. If not, it means that your graphics card does not support DX12
