You see, tesselation
DOES BRING ADDITIONAL POLYGONS into the scene. Simply speaking, it "takes" a low-poly model and transforms it into a high-poly one (which, obviously looks better, if you are close enough to see the difference
).
This technology makes modeling easier, but it does not unload the GPU. On contrary, it loads it more. However, the modern (read, DX11 - compatible) GPUs can "chew" a lot more polygons, then the older ones, hence, allowing use of this technology without the significant performance drop.
PS Bomb craters are already 3D.
