How expensive is the World Aligned Texture node?

Thanks for the help guys,

I have the Assets unwrapped already so the UV’s are not the problem.The issue I have is that with the same texture applied to each of the modular assets the repeating pattern was becoming very obvious. The other issue I was having is that when I got close to an object in VR the material would become very blurred, even with High Res textures! The only way around this was to further tile the texture which then added to the repeating pattern problem.
So,I now have the world aligned texture over the entire static mesh/es and it has dealt with the tiling and resolution issue. but am I now just creating more problems for myself further down the line?
I’m currently getting the golden 90fps but am worried I’m going to run in to problems later.

Finally, I can fairly easily drag these Assets in to substance and add a quick tri-planar projected texture there. the issue though is that to get the resolution to an acceptable level I’m probably looking at 5 or 6 - 4K textures. At what point does the cost of using multiple high res textures outweigh the use of the world aligned node?

Thanks so much for your replies, the UE community being awesome as always!
