Key Features
- CineFX 4.0 Shading Architecture
This is a groundbreaking new hardware technology that pushes 3D real-time graphics one step closer to film quality. It offers infinite length shader programs, dynamic flow control, displacement mapping, vertex frequency stream divider and Multiple Render Target (MRT) technology. Previously, highly complex effects were not possible without sacrificing
performance and precision, because of long shader programs that required many
computational passes.
- SLI enabled
NVIDIA® SLI™ (Scalable Link Interface) technology is a revolutionary approach to scalability and increased performance. NVIDIA SLI takes advantage of the increased bandwidth of the PCI Express™ bus architecture, and features hardware and software innovations within NVIDIA GPUs (graphics processing units) and NVIDIA MCPs (media and communications processors)
- PureVideo Technology Support
Watch videos on your desktop PC, notebook PC, or HDTV without the annoying artifacts and imperfections of traditional PC-based video solutions. NVIDIA® PureVideo™ technology delivers smooth HD video in all formats and with superb picture clarity. And the high-precision subpixel processing enables videos to be scaled to any size so that even small videos look like high-resolution videos.
- UltraShadow II
More photorealistic scenes and environments in your games, without compromising PC performance. Complicated lighting and shadow effects become practical and next-generation games rise to the next level in cinematic realism.
