Why does DoomGuy move slower in the newer games when he's faster according to the lore?

We're led to believe he's stronger and faster after going into the Divinity Machine, but his sprint speed is much lower after Doom 64. One of the reasons I found 2016 boring is because his movements felt sluggish.

Eternal does have the same problem in that he's slow on foot, but at least the game introduced Dash to make it more enjoyable.
