Question What is most optimal when considering GPU Instancing

I would like to know which option is more optimal when it comes to using a single pallet texture:

A: Have many materials designated to each object with instancing enabled. Each Mesh has its own material.
B: Have 3 variations of the same material(Spec, Metal, Standard) and apply it to different meshes. So each Mesh in my scene is using one of the 3 Materials.

Objects are static (Don't move) in both cases.

 

B is more optimal. Sharing the same material (and preferably also mesh) is a lot more performant and this can make use of dynamic batching!

Better answer: try it and run the profiler

 

Thank you for your reply.

Thats a great idea, I will try it in a sperate scene and see what results I get!
