nVidia X 3dmark2003 já é guerra... não fiquem triste :D

Uma nota assustadora vindo da nVidia sobre o novo 3DMark2003. A empresa está falando que o benchmark não é uma maneira válida de verificar a performance das placas, e por isso está desconsiderando o mesmo como principal ferramenta de benchmark para placas 3D. Com esse tipo de afimarção podemos concluir que a performance da GeForceFX não esteja fazendo frente com a Radeon 9700. Vale lembrar que os testes em Pixel Shader estão usando a versão 1.4, que está presente nas placas baseadas no R200, ao contrário das placas GeForce 3 e 4 que usam a versão 1.1, e por isso gastam mais tempo para renderizar uma mesma cena. Confiram abaixo o comentário da nVidia sobre o 3DMark2003, seguido da resposta de Aki Jarvilehto, representante da Futuremark, e a última nota, que explica a vantagem do Shader 1.4 em cima da versão 1.1.

Nvidia has contacted us to say that it doesn't support the use of 3DMark 2003 as a primary benchmark in the evaluation of graphics cards, as the company believes the benchmark doesn't represent how current games are being designed. Specifically, Nvidia contends that the first test is an unrealistically simple scene that's primarily single-textured, that the stencil shadows in the second and third tests are rendered using an inefficient method that's extremely bottlenecked at the vertex engine, and that many of the pixel shaders use specific elements of DX8 that are promoted by ATI but aren't common in current games.

In response to Nvidia's statements, Futuremark's Aki Jarvilehto said, We've been working for the last 18 months to make 3DMark 2003 an accurate and objective benchmark. Nvidia was one of our beta members until December, and it's not our place to comment on why they've decided to withdraw from the program. After working on the project for almost two years with all the leading manufacturers, we do strongly believe that 3DMark 2003 is an accurate representation of game performance for modern 3D accelerators.

Futuremark has made use of 1.4 pixel shaders. Hardware that is capable of using 1.4 shaders (any dx9 compliant card, and the 8500/9000/9100) are going to see a performance improvement as less rendering passes are required compared to 1.1 shaders. With 1.1 pixel shaders, objects need one rendering pass for depth buffer initialization and three passes (stencil pass, light fall-off to alpha buffer, and diffuse and specular reflection) for each light source. When 1.4 pixel shader support is available only one pass for each light source is needed.
