Hey,
i played arround mixing a normal and bump map. When i use "Add" there is a big difference between CPU and GPU.
It is the same with "Subtract" but no problem when i use "Mix", "Multiplay" or "Divide"
CPU
GPU
Nodes

What Lux version are you using ? Can you post a simple test scene with a cube and your material definition ?

Similar result like yours.
So how do we fix it? I mean there shouldn't be a difference, right?

Correct. Some one should open an Issue in Github.
