Yeah, what they do is very professional, surprisingly fun to watch despite the highly technical elements, and very useful for someone like me who does reviews. Since a lot of devs intentionally mud the water by confusing upscaled 4K, native 4K, locked 60fps or fps up to 60, etc. it's hard as hell for someone without the technical abilities to write about the technical aspects of the game. DF is a lifesaver in that they provide precise and useful info. Their ARK Switch video is truly something for example. I could have used DF some years ago when I was at a review event for a game, where the devs claimed the game has the same resolution on X1 as it does on PS4, so I trusted their words and wrote their claim in. Release day arrived, embargo lifted and it turned that was false. Stuff like that is why I love DF.
