I've played it for 12 or so hours on my non-pro PS4. Had to restart once because the controls stopped working ("mouse cursor" just moved to the bottom of the screen/huge delay in input) and one time a hint overlay got stuck and covered 1/3 of the screen and couldn't be closed. Savegame reload fixed it (the other bug required a restart).

The gameplay is fun and I don't regret buying it (physical copy). But I'm a sucker for the cyberpunk theme and Witcher 3 is probably my #1 console game of all time so maybe I'm willing to accept too much. Far from unplayable though and I don't really care for maxed out graphics so the look and feel is just fine for me.
