This is the latest update of Microsoft's Direct X technology. You'll need this to play pretty much every game that requires a 3D card, which to you and me means those tasty 3D multi-player shoot-em-ups like Quake. Upgrading will benefit all 3D gamers who already rely on Direct X 6.0, offering enhanced graphics and increased frame rates. Version 7.0 is optimised for the Pentium III chip.
