How to Install Directx 9.0 B on Windows 10
Install DirectX 9 on Windows 10 to improve performance on older video games as well as fix various issues, glitches and bugs that you might be experiencing.
This guide is valid for any older game that benefits and runs on old DirectX versions.
Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, but especially game programming and video, on Microsoft platforms, such as your Windows Operating System.
Originally, the names of these APIs all began with Direct, such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so on. The name DirectX was formed as a short form of all the APIs (the X standing in for the particular API names) and later became the name of the whole collection of APIs. When Microsoft laterdecided to develop a gaming console, the X was used as the basis of the name Xbox to indicate that the console was based on the same DirectX technology. The X initial has been carried forward in the naming of APIs designed for the Xbox such as XInput and the Cross-platform Audio Creation Tool (XACT), while the DirectX pattern has been continued for Windows APIs such as Direct2D and DirectWrite.
Windows 10 comes packed with the newest edition of DirectX 12. My favorite game SWTOR and many other older game titles use DirectX 9. In order for it to display its beauty, the system needs to emulate all the DirectX 9 effects, which may slow it down and result in a poor performance.
By installing the DirectX 9 package manually, we stop that process of simulation and allow our PC to use the original files the game is designed for, thus, in theory at least, speeding the process up. This installation wont make the game run smooth and flawlessly, but it will likely boost it at least a bit. I have done this since the game's launch in 2011 on multiple versions of Windows – Windows 7, Windows 8 + 8.1 and now Windows 10 .
DirectX 9 does not replace DirectX 11 or DirectX 12, it adds additional libraries to be used by games and software that is designed to best work with them.
The installation is simple. Download the file from the link I have provided below (leading to the official Microsoft website) and install with no manual changes during the process. By doing that, you DO NOT remove the DirectX 12, no, it just installs extra libraries and gives the game you play an option which ones to use. If the game can benefit from DirectX 11 or 12, it WILL use those. There is no overriding or replacing, the installation just adds another layer.
You can get a Windows 10 Pro for $28 from Kinguin (use code "vulkk" for extra 3% OFF) – I got a copy myself from them :)
One last note. Installing DirectX 9 does not hurt your system, it will not break anything. The link provided below is from Microsoft's official website.
You can download the old DirectX 9 from here:

If you have any troubles, leave a comment and let me know of YOUR experience. Did DirectX 9 improve the performance of the game for you or it feels and acts exactly the same as before.
