As special effects in the latest Hollywood blockbuster films continue to advance at an incredible rate, you’ve come to expect amazingly realistic explosions, true-to-life ocean waves in a sea storm, and incredibly vivid colors in animated features. So there's no reason you should settle for anything less than the best when it comes to your games. Architected for high-level programming languages like Cg, the NVIDIA® GeForce FX GPU’s first- and second-generation NVIDIA®  CineFX engines produce gaming effects on par with the hottest motion pictures. Combined with 128-bit studio-quality color processing technology, 3D worlds and characters are more real than anything that's come before. Hollywood dreams are now a desktop reality.

With the introduction of the GeForce FX 5900 GPUs, the second-generation CineFX 2.0 engine optimizes all stages of the pixel pipeline, doubling the floating-point pixel shader power of its predecessor. This major jump forward translates directly to a 2x increase in floating-point shader power, and a visible performance boost from the faster, more efficient execution of pixel shader programs.

The CineFX engine allows developers to easily apply their distinctive style to digital content, achieving cinematic visual effects in real time with specialized graphics programs called shaders. Powered by CineFX, GeForce FX shifts the focus from simple pixel fill rate to sophisticated pixel shading. The GeForce FX eliminates many programming barriers previously associated with pixel shaders by supporting long programs for even the most elaborate effects, and conditional branching capabilities for greater efficiency. To maximize programming choice, CineFX includes the most complete hardware feature implementation for both OpenGL® and Microsoft® DirectX® environments, including total support for the latest DirectX 9.0 vertex and pixel shader specifications.

PIXEL SHADERS 2.0+
CineFX engine raises pixel shading to a first-class programmable citizen of the graphics pipeline, and gives developers a host of new capabilities for controlling pixels and producing effects that are only limited by the imagination.

Advanced CineFX features include the support of 1024 instructions in a single rendering pass, allowing for complex effects that aren’t practical in any other architectures. For example, volumetric effects such as smoke, fur, fire and grass add significant depth and realism to a scene, but require multiple instructions to achieve. What CineFX achieves in one rendering pass takes competing products many more. Procedural texture support obviates the need for spending video memory on large texture maps, and allows for subtle, realistic differences across surfaces. Complex lighting can dramatically improve the realism of images, but traditionally adds to rendering time. With the GeForce FX GPUs all of these gorgeous enhancements are possible without sacrificing performance.

In addition, shaders can now handle multiple textures in one pass for optimized execution, making layered or mixed effects such as paint peeling off a metallic surface possible. The CineFX engine allows fetching from up to 16 unique texture maps in a single pixel shader program. These textures can be anything that defines surface or subsurface properties such as bump maps, displacement maps, gloss/specular maps, environment maps, shadow maps and albedo maps.
