08:38 for textures, they run through the other settings too.Sadly dont see screenshots on either link and I am not watching that full video, but if you could tell me the timestamp ill check it, if there is no noticeable difference, thats kind of unusual, but of course its possible to upres textures without actually adding detail, in which case its pointless. Maybe thats what the devs did in that game.
Bear in mind visual differences are a matter of opinion, one person might consider e.g. MSAA a game changer and someone else see's it as a very minor improvement and not worth it. Which is why I am not just blindly accepting the statements in the first two links.
