Landscape and mesh draw calls

Hello. I’m creating a landscape for an open world game and my goal is to optimize the performance of the map.
Following Epic Games live tutorial or reading the docs, I know that in order to achieve that I have to follow some
recommended settings.
The map I’m using right now is made of 1009x1009 vertices, 64(8x8) components, 2x2, 63 quads section. But, I need a bigger map.
I’ve tried the one with 2017x2017 vertices but it’s way too big for my purpose. So, since there is no recommended average map between them, I’m trying a 144(12x12) components, 2x2, 63 quads section.
I’ve measured the mesh draw calls and the increment is 100 draw calls more. Is it reasoneable?
I just want to know, since the number of recommended components are always a power of 2, is it a problem doing a 12x12?
Thank you.
