He has one fight scene before being transformed into a computer controlled whatever the hell he was. When he was Wade Wilson, he was a high-end bullet-timer.
He has one fight scene after he was literally transformed into a different being: a being that was commanded remotely, and had no free will at all, had a metal skeleton, had powers grafted into a shell of a human. In that scene, he never comes close to showing bullet-timing. He also never really shows that he's Wade Wilson. It's Wilson's body, but not his mind or abilities.
