Not sure if anyone mentioned it, but this is for eastcore (i kinda stopped reading at the last page and fast-forwarded the last one),
I remember talking to Faf about this and apparently the required space to store a very high resolution model ends up being higher that the space required to store a texture/normal map that achieves similar results (obviously without the benefit of being real geometry).
Displacement maps can help us with that, but in the end saying "if there is not enough RAM, dump the textures and put lots of polygons instead" is wrong.
