Lately I've been interested in modernizing the geometry pipeline in the rendering engine, for example reducing the vertex shaders. It's a well known fact that geometry shaders are not making efficient use of the GPU hardware, but similar issues could apply for vertex and tessellation shaders too, just because there is a need for pushing…

The article discusses the potential benefits of reducing the use of vertex shaders and moving more functionality into pixel shaders in the rendering engine. This can help eliminate vertex shader permutations, reduce memory traffic, and simplify shader programming. However, there may be potential drawbacks related to the increased burden on pixel shaders and register pressure.
