A new breed of visually striking games promises to light up computer screens with even sharper, more lifelike graphics than ever before. But unlike the popular “Gears of War” or “MotorStorm,” the games won’t be debuting on Sony’s PlayStation 3 or Microsoft’s Xbox 360 consoles.

Instead, the PC is returning to the pinnacle of video game graphics–thanks to some under-the-hood tweaks in Microsoft’s Vista operating system.

The technology behind these improved visuals, called DirectX 10, is the result of a collaboration among video game developers, graphics card makers and Microsoft. For years, they have been working to streamline and standardize the software used by Windows-based PCs to display graphics. The latest improvements, many believe, far surpass even the very best of what the consoles are capable of.
