	*** On earlier versions of Source ({{src04\|1}} up to {{src13\|1}}), it had a Hardware DirectX level system (similar to [[Wikipedia:Direct3D#Feature_levels\|feature level system]] in Direct3D 10 and later) that allowed the game to render on older GPUs supporting only DirectX 8.0, 8.1 (Pixel Shader 1.x), by disabling DirectX 9-only graphical features not available on these older cards. Previous versions of Source ({{src04}} and {{src06}}), as well as Source 2013 RTX Remix games, also had support for DirectX 7.0 and 6.0 render paths. This can be changed using the {{code\|[[mat_dxlevel]]}} console command, or by using the {{code\|-dxlevel}} [[command line argument\|launch option]].		*** On earlier versions of Source ({{src04\|1}} up to {{src13\|1}}), it had a Hardware DirectX level system (similar to [[Wikipedia:Direct3D#Feature_levels\|feature level system]] in Direct3D 10 and later) that allowed the game to render on older GPUs supporting only DirectX 8.0, 8.1 (Pixel Shader 1.x), by disabling DirectX 9-only graphical features not available on these older cards.
