Compare it to Skyrim, itself four years old, and the improvements are less massive. New Vegas is five years old, though, and running on an engine two years older, so significant changes should be expected.
The Boston wasteland is a huge expanse of diverse terrain and settlements, brought to life with lighting both subtle and overt, and countless tiny details. Having recently replayed Fallout: New Vegas, I was immediately struck by the visual improvements lavished on Fallout 4. Tested on a Intel i5-3570K GHz, 8 GB of RAM, GeForce GTX 970, Windows 10.
