Performance Tip: Favor advanced single-pass shaders over simple multi-pass shaders

GMA X3000 tends to be more fill rate limited than compute limited. This means that when given the choice of using a simpler shader with multiple passes or a more advanced shader model with a single pass always favor the advanced shader with a single pass. GMA X3000 natively supports advanced shader models such as SM3.0. It executes them efficiently while it tends to be fill rate limited when doing multiple passes with simple shaders.
