-> I've already posted this question but I had no answer.

-> Which of these 2 modelisation is the most performant ? (on RE2 and iR)
-> - 2 faces with opposite normals,
-> - 1 face with 2-sided lighting.

People can correct me they feel otherwise..... but

It is considered most functional to have 2 faces with single sided
lighting and *backface* removal on.

If your object is single sided, when you look at it from the back side
it will not be drawn when backface removal is enabled. Enabling Backface
removal will usually gain you 20% increase in drawing times on average.

Cheers,
