NVIDIA CineFX 3.0 is poised to unleash a new level of programming
creativity. With full DirectX 9.0 Shader Model 3.0 support, the newest
Video-338/348PCI series will soon power a new generation of games
with unmatched realism, digital worlds with mind-blowing complexity,
and lifelike characters that move through cinematic-quality
environments.
Intellisample Technology
The industry’s fastest antialiasing delivers ultra-realistic visuals, with no
jagged edges, at lightning-fast speeds. Visual quality is taken to new
heights through a new rotated grid sampling pattern.
UltraShadow II Technology
Video-338/348PCI series of GPUs delivers 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 Video-338/348PCI 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 III 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.
NVIDIA UltraShadow II gives developers the ability to calculate shadows
much more quickly by eliminating unnecessary areas from
consideration. By defining a bounded portion of a scene (called “depth
bounds”), and focusing calculations only on the area most affected by
the light source, developers can greatly accelerate the shadow
generation process. With the ability to fine-tune shadows within critical
regions, developers create incredible visualizations that mimic reality,
and still achieve awesome performance for fast-action games.
UltraShadow II also works perfectly with NVIDIA® Intellisample 3.0
technology to ensure that shadow edges are properly antialiased.
