How to Determine DirectX version and Shader Model You're Running

A guild to finding the DirectX version and Shader Model running on your PC.

Microsoft DirectX, also simply known as DirectX is a set of APIs used in the development and programming of video games on Microsoft operating systems (Windows and Xbox). Introduced in 1995, shortly after the release of Windows 95, it has since been bundled in every version of Windows since Windows 98.

Since the release of DirectX 8.0 graphics cards have used programs/instructions known as Shader Models to help interpret instructions on how to render graphics sent from the CPU to the graphic card. Many new pc games are increasingly listing Shader Model versions in their system requirements.

However these shader versions are tied to the version of DirectX that you have installed on your PC which is then in turn tied to your graphics card. This can make it difficult to determine if your system can handle a certain shader model or not.

To determine the version of DirectX you have running:
1. Click on the Start menu, then "Run".

2. In the "Run" box type "dxdiag" (without the quotes) and click "Ok". This will open up the DirectX Diagnostic Tool.

3. In the System tab, listed under the "System Information" heading you should see a "DirectX Version" listed.

4. Match your DirectX version with the Shader version listed below.

Once you've determined the version of DirectX running on your PC you can use the below chart to determin what Shader Model version is supported.

Please note DirectX versions prior to DirectX 8.0 do not support shader models
 • DirectX 8.0 - Shader Model 1.0 & 1.1
 • DirectX 8.0a - Shader Model 1.3
 • DirectX 8.1 - Shader Model 1.4
 • DirectX 9.0 - Shader Model 2.0
 • DirectX 9.0a - Shader Model 2.0a
 • DirectX 9.0b - Shader Model 2.0b
 • DirectX 9.0c - Shader Model 3.0
 • DirectX 10.0* - Shader Model 4.0
 • DirectX 10.1* - Shader Model 4.1
 • DirectX 11.0† - Shader Model 5.0
 • DirectX 11.1† - Shader Model 5.0
 • DirectX 11.2‡ - Shader Model 5.0
 • DirectX 12 - Expected Release December 2015
* Not available for Windows XP OS
† Not available for Windows XP, Vista (and Win 7 prior to SP1)
‡ Windows 8.1, RT, Server 2012 R2

One recommendation prior to installing a newer version of DirectX is to ensure that your graphics card supports that version of DirectX.
