Should I bother with master/instance shaders when just doing two variations?

Hi Everyone,

I’m finding myself doing a lot of duplicating shaders to do two color variations of them just changing one or two things like color mult or a texture map.

Several of these end up as MID’s as well.

Is it worth doing a master shader and then two instances in this case? Would it save enough load times, shader build times cpu, memory?
I will end up with three shaders but maybe its still worth it?

Does anyone know?

Cheers
