Default Re: Far Cry Benchmarks - Shader Model 3.0 performance

UPDATE: It has recently come to our attention that our 4xAA/8xAF benchmark numbers for NVIDIA 6800 series cards were incorrect when this article was first published. The control panel was used to set the antialiasing level, which doesn't work with FarCry unless set specifically in the FarCry profile (which was not done here). We appologize for the error, and have updated our graphs and analysis accordingly.

For a more positive update, after a discussion with CryTek about the new rendering path, we have learned that the lighting model implimented in the SM3.0 Path is exactly the same as was used in the SM2.0 Path. The only exception is that they used the conditional rendering (branching in the pixel shader) to emulate multipass lighting in a single pixel shader. The performance gains we see actually indicate that PS3.0 branching does not have as significant a performance hit as previously thought (and proves to be more efficient than using multiple pixel shaders in a scene).
