cpu_level / gpu_level

cpu_level / gpu_level is a console variable available in all Source games since Left 4 Dead. It is the successor of mat_dxlevel on Source 2007 and earlier, and used to adjust shader & particle details.

Note:This console command is hidden by default (in Left 4 Dead 2), but can be changed using SourceMod, using sm_cvar cpu_level or sm_cvar gpu_level, VScript using script Convars.SetValue("cpu_level", "0-3") or script Convars.SetValue("gpu_level", "0-3"), or can be forced via launch options.

This can be also changed through in-game video options.
