Accurate shadows are critical for realistic and believable scenes in games. But the complex interactions between light sources, objects, and characters involve elaborate programming. For every frame in a game, every light source must be analyzed relative to every object, potentially bogging down the PC and affecting your gameplay. The NVIDIA® GeForce™ 6 and GeForce 7 Series of GPUs deliver the patent-pending NVIDIA® UltraShadow™ II technology, which can be applied to today’s games to build stunning visual effects and to create distinctive digital environments. With a system powered by a GeForce 6 or GeForce 7 Series GPU, anytime a game or application calculates shadows, UltraShadow II will enhance the overall performance.
With UltraShadow II hardware, the more passes that are required for the lighting and shadow calculations in a scene, the more significant the performance improvement, with the most complex scenes achieving the most noticeable results. Thus, emerging next-generation games, that employ multiple light sources with many visible objects in each scene—such as DOOM 3™ from id Software—will see dramatic improvements in execution speeds. The technology advancements in UltraShadow II also deliver a 4× performance increase (compared to the previous generation) for passes involving shadow volumes.
