performance aint much better when there's a ton of them, for this could definitely at least use instancing instead of drawing them 1 by 1

From what I know up to this moment, the biggest performance drop is not drawcalls itself, but material switches

Material = Uniforms + textures + states (backface, blending, depth write, depth culling)

Ah, right. VBO/IBO/VAO are also can be considered as states here

and since this is for an heightfield could optimize with a shader to calculate x y and not send it ofc
