Games are using longer more complex shader effects. ATI and NVIDIA have taken slightly different approaches to increase pure Shader performance. NVIDIA has increased the number of Pixel Shader Pipelines, and ATI has gone the route of increasing the number of Pixel Shader Processors to each Pixel. The X1600XT has 4 Pixel Pipelines, but 12 Pixel Shader Processors and 5 Vertex Shader pipelines.

Microsoft released DirectX 9.0 in 2002 to coincide with the release of the ATI 9700 Pro. They had released a new DirectX every year or so, but with the release of DirectX 9.0 they decided to lump Shader Model 3.0 in with 2.0, to allow a longer period between DirectX launches. The key components of SM3.0 include Pixel Shader 3.0 and Vertex Shader 3.0, 32-bit precision throughout the pipeline and more.

Pixel Shaders are small programs performed on pixels to give special effects. Games like F.E.A.R. and Oblivion use Pixel Shaders throughout. Oblivion is a visual masterpiece. Pixel Shaders are used in the water, in the shiny reflective armor of the knights, in the skin tones and more. The developers developed Oblivion to play on the highest end video cards at the time of launch of the game, but it plays on a X1600XT with all of the same visual quality as the X1900XTX, just slower.

Vertex Shaders are also used in games like Oblivion and F.E.A.R.. Oblivion uses Vertex Shaders in the facial animation of the characters, in the animation of the monsters and movement of the characters, the grass, the weather effects and more. Oblivion and upcoming games like it require a lot of vertex shading power to run smoothly.

One feature ATI cards can do that NVIDIA cards cannot is HDR+MSAA at the same time. HDR reflects the fact that the human eye can distinguish between differing contrasts of thousands to one. The effect where you move indoors with dim lighting to outdoors can be simulated with HDR rendering. HDR combined with MSAA makes for the absolute best image quality in a game like Oblivion bar none. ATI chose to use the PCI Express bus to handle data transfers between two X1600XT cards when Crossfire mode is enabled. The high-end cards like the X1900XTX and X1800XT require a master card to function when two cards are installed. ATI will likely not require a Master Edition card with their future cards, but we'll see.
