No, you're thinking of bump-maps. Bump-mapping is a texture trick to make it look like there's depth. Dsiplacement maps are textures that actually modify vertices in 3-dimensions to achieve depth.
Here's the tessalation shown in Aliens vs. predator. Running on AMD hardware. Should give you some indication of the use in real games.
