StandardMaterial performance

Hi all,

Can anybody tell me a bit about the StandardMaterial perfomance (and possible optimizations).

If we only use diffuse (map, color tint) will the rest be stripped or skipped? Kinda want to avoid running over and checking for specular, opacity, normals, etc. for each pixel if we don’t use it.

Just wondering - before I start researching new shaders.
