Note:This command is not available in any game made using Left 4 Dead engine branch and later branches, or in some third-party branches.Furthermore, since around
Source 2007 or Source 2009 up to Source 2013, only DirectX 8.0 and 8.1 materials are supported, DX7 and earlier was dropped.mat_dxlevel changes the DirectX (feature level) 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 - Softer shadow ...
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 mat_dxlevel 98 - Xbox 360 only mat_dxlevel 100 - Source Filmmaker only, this does not enable DirectX 10 support on vanilla (unmodified) engines.
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)
Warning:Using -dxlevel launch parameter makes alt tabbing in and out of the game really slow, this also resets all video configs. It's better to use +mat_dxlevel launch parameter instead, or to place mat_dxlevel command inside a config file.Futhermore, -dxlevel should be only used a workaround to fix the issue that the game defaults on DX8 mode which may happens on some modern hardware.
