DirectX 6

DirectX 6-class graphics cards include the Nvidia TNT2 and Matrox G400.

DirectX 7

DirectX 7-class graphics cards include the Nvidia GeForce 256, 2, 2MX and 4MX cards and the ATI Radeon 7xxx series.

• Blob shadows
• Displacement map texture blending

DirectX 8.0

DirectX 8-class graphics cards include the Nvidia GeForce4 Ti and most of the GeForce FX 5x00 series (while technically DirectX 9 cards, the latter suffer from major performance problems with the DX9 rendering path).

• Refractions with the use of a du/dv map
• Dynamic shadows
• Directional lighting on world brushes using normal maps
• Cube-mapped specular effects
• Cube-mapped water
• Low-quality reflective water (used sparingly)

DirectX 8.1

DirectX 8.1-class graphics cards include the Nvidia GeForce FX 5800 and 5900 and the ATI RADEON 8500/9100 and 9000/9200 cards.

DirectX 9

DirectX 9-class graphics cards include the Nvidia GeForce 6600 and 6800 series and the ATI RADEON 9500/9600, 9700/9800, X300/X600 and X800 cards.

• Refractions with the use of a bump-map
• High-quality reflective water (used frequently)
• Softer edge dynamic shadows
• Normal-mapped lighting on models
• Improved-quality specular effects
• High dynamic range rendering
