This short trailer shows some of the DX9-specific effects possible in Valve's Source engine, which powers Half-Life 2.
Specifically shown in this trailer:
- High-dynamic range rendering (for rendering realistic outdoor scenes,
produces glows and saturated colors in bright areas of the scene).
- Bump-mapped characters (containing both diffuse + reflective bumpmapping, DX8 only has reflective bumpmapping).
- Soft shadows
