[Question] Best material practice for Hololens

[Tim-Potratz]

Hello,
I'm not quiet sure if this question fits here, but its something I have been thinking about for a while.
In Unreal Engine you always get the number of instruction a shader/material takes to get displayed (276 for example), some instructions take longer to execute than others. For example the instruction 'power' can get really expensive to compute, while the 'add' instruction is an extremly simple one.
The question is what is prefferd for the best performance on the Hololens, have many simple instructions or only a few complex once?

I'm not sure if I'm getting this right, so please correct me.
Thanks for the support!
