An works by intercepting the communication between the Counter-Strike 1.6 game engine and the graphics driver.

This forces the driver to render player models even when they are behind solid geometry, making walls semi-transparent or turning player models into bright, visible wireframes.
, players can replace the legitimate version of this file with a modified one. This custom driver hooks into the game's core rendering pipeline, allowing it to alter how visuals are processed before they reach the user's screen. 2. Mechanics of Transparency and Depth
