DirectX9 Software introduction
DirectX 9.0c is referred to as DX9 for short, which is a short form of DirectX 9.0C that people is used to search. Compared with the past DirectX 9.0B and Shader Model 2.0, the improvement of DirectX 9.0C is to introduce comprehensive support for Shader Model 3.0 (including Pixel Shader 3.0 and Vertex Shader 3.0).
Microsoft DirectX9.0C official download is such a set of technologies: DirectX 9.0C aims to make Windows -based computers a ideal platform that runs and displays rich multimedia elements (such as full -color graphics, video, 3D animations, and rich audio). Essence DirectX 9.0C includes security and performance updates, and many new features covering all technologies. Applications can access these new features by using DirectX API.
DirectX 9.0cMicrosoftThe company developed a widely used API, which contains Direct Graphics (Direct 3D+Direct Draw), Direct Input, Direct Play, Direct Sound, Direct Setup, Direct Media Objects and more. Component, DirectX was developed at the beginning of development Make up the lack of Windows 3.1 system on graphics and sound processing capabilities, and now it has developed into an interface that has a decisive impact on all aspects of the entire multimedia system.
DirectX9.0C officially downloads and enhances 3D graphics and sound effects, and provides a common hardware -driven standard for designers, so that game developers do not have to write different hardware for each brand's hardware to write different ones.DriverIt also reduces the complexity of user installation and setting hardware. Literally, Direct means direct meaning, and X in the back represents a lot of meaning. From this point of view, we can see that the appearance of DirectX is to provide direct services for many software.
DirectX9 Functional characteristics

DirectX9 Installation method
1. Download DX9.0C (DirectX After 9.0c), get a compressed package locally on the computer, use it360 compressionAfter the software is decompressed, double -click the .exe file into the DirectX9.0 installation interface, click [YES]
2. Select DX9.0C (DirectX 9.0c) Installation position, click [Browse] to open the interface of the balancing, and you need to find "dxsetup.exe" to install DX software.
3. Enter the DirectX 9.0C Installation License Agreement interface. You can read the terms in the protocol first, click [I accept this protocol], and then click [Next].
4. DX9.0C (DirectX 9.0C) is under installation, and you need to wait patiently for the software installation.
5. DX9.0C (DirectX 9.0C) installation is complete, click [Completed] to exit the software for installation.

DirectX9 Common problem
1. What is the software ofdx9.0c? What is the role?
For example, when you play games under the DOS, you can play it when you play games under the DOS before. You can first set the brand and model of the sound card first, and then set it up IRQ (interrupt), I/O (input and output), DMA (access mode), if any settings are not right, then the sound of the game will not be released.
This part of the settings not only hurt the players, but also have a headache for game developers, because in order to allow the game to run correctly among many computers, developers must Sound card hardware data is collected, and then different drivers are written according to different API (application programming interfaces). This is difficult to complete for game production companies, so there are few multimedia games at that time.
Microsoft saw this problem, and launched a common application interface for the manufacturers -DirectX. As long as this game is developed according to DirectX, no matter what graphics card, sound card, all can play, and can also play, and can also exert it. A better effect. Of course, the premise is that your graphics card and sound card driver must also support DirectX.
2. Can WinXP use DX10, DX11?
No, Microsoft has long said. If you want to play DX10, DX11 games, please use Vista or Win7 or even Win8 in the future. Microsoft will also give up WinXP updates soon, so if you want to play games based on DX10 and DX11, please change the operating system.
3. How do I think the system's DX9.0C version?
Start-Run-Enter dxdiag to confirm. In the pop -up dialog box, you can see the DirectX version of the system (non -hardware) of the system (non -hardware)
DirectX11Compared with DirectX9 software
DirectX11It is currently relatively new DX, which reflects the good effect and performance of the new game, but requires the support of the same hardware. It is recommended under economic permission. Just like the VCD and DVD video disc, VCD is DirectX9. DVD is the DirectX11 game graphics. It has obvious differences between DirectX9. The relatively complete DX reflects the support and compatibility of old games, but does not support new games, and the screen is not realistic.
Users can be selected from the appropriate download and use according to their actual situation.
DirectX9 Update log
1. DX9.0C has added support for ATI 3DC texture compression technology
2. DX9.0C adds the Shader Model 3.0 supported by the GeForce 6 series graphics card of Nvidia
3. DX9.0C has fixed some other small mistakes
