One of the most exciting developments in Windows Vista is the groundbreaking graphics technology. Many of the newest Windows games take full advantage of the next-generation graphics technology in Windows Vista called DirectX® 10. DirectX® 10 provides an incredibly detailed experience for gamers of every type, and enables game creators to increase a game's level of realism, enhancing details and complexity in gaming worlds, apply effects like dynamic lighting and weather, and much more.
While Windows Vista is fully compatible with games and hardware that use older versions of DirectX®, the new DirectX® 10 features are available with a DirectX® 10 compatible graphics card and games designed to take advantage of this new technology. Adding a DirectX® 10 card to a PC running Windows Vista is like turbocharging your gaming experience. Existing games (most of which were written using DirectX® 9) get world class performance, while unlocking the new generation of gaming graphics with DirectX® 10 optimized games.
