I just changed the resolution scale in the game all the way up to 2 (max) and the blurriness has gone.
The controllers seem to have things like the default action button set to the right joystick press down. Seems, weird. When the menu comes up, showing some previous style of controller with a ring around them, it shows the action button as the equiv A key, but it isn't. No option, not seen so far, to adjust those within the game. Guessing that would need to be done within the Steam bindings for the game..?
Point taken on games and longevity, 20 minutes would be good for me, lol. Like most of my Steam library.
