mat_dxlevel changes the DirectX mode used within a Source game. The player is only able to use modes that their hardware supports. The format is

 mat_dxlevel [DirectX version]
 mat_dxlevel 70
 mat_dxlevel 80
 mat_dxlevel 81
 ...

For DirectX 9 the value depends on the hardware's capability:

 mat_dxlevel 90 - DX9 with Shader Model 2
 mat_dxlevel 95 - DX9 with Shader Model 3

This can also be specified with Launch Options, use +mat_dxlevel [DirectX version] on the launch options of any Source game to do so. Alternatively, you can use -dxlevel [DirectX version], however this specifies a number of extra presets, including but not limited to:

  • Resolution
  • Windowed/Fullscreen status
  • MSAA quality (mat_aaquality) and sample count (mat_antialias)
  • Motion blur (mat_motion_blur_*)
  • Shadow depth textures
  • Gamma (mat_monitorgamma)
