Mat dxlevel

Template:Otherlang2Template:Wrongtitle mat_dxlevel changes the DirectX mode used within a Source game. The player is only able to use modes that his/her hardware supports. The format is

 mat_dxlevel [DirectX version]
 mat_dxlevel 90
 mat_dxlevel 81
 mat_dxlevel 80
 mat_dxlevel 70
 ...

There are some special values used depending on the hardware's capability:

 mat_dxlevel 95 - DX9 with Shader Model 3
 mat_dxlevel 98 - DX9 on DX10 hardware (SM 4)

This can also be specified with Launch Options, use +mat_dxlevel [DirectX version] on the launch options of any Source game to do so. Alternately, you can use -dxlevel [DirectX version], however this specifies a number of extra presets, including resolution and quality.
