Introduction
This is a description of what each version of DirectX is capable of, for reference when creating fallback materials. Under each heading are features not available in previous versions of DirectX.
To test lower-quality DirectX levels on a more advanced graphics card, use the mat_dxlevel console CVAR. Set it to 60, 70, 80, 81 or 90 to set the corresponding DirectX version; it is not possible to run at a higher level than the graphics hardware is capable of.
