Did you even watch the video? There are plenty of comparisons with Fidelity Mode. This video is sloppy for different reasons. For one, he doesn't even touch upon the performance penalty of the various settings. For two, he tests only an RTX 2070S. What about a 3080? His optimized settings don't really feature a benchmark of what they gain over higher or lower settings, and his CPU analysis is woefully lacking. Despite this, the video is still almost 30 minutes long, chiefly due to the fact that half of it is spent talking about the issues plaguing the game. I think Alex just isn't interested in doing this kind of content where all he does is pick out the problems for the devs. This is a post of his on era,
But you are correct in your statement yesterday; DF rushed out a video, just like Sony rushed out R&C, and DF's analysis video is also unpolished, just like R&C.
