No, they don't say that at all and are quite precise in this instance. You are mis-reading what they're saying. DF doesn't talk about "console settings", but default settings (To which they add volumetric clouds and better texture filtering):
There's no need to talk about better texture filtering, it's always at 16x AF on PC for comparisons and it comes at no performance cost. My point is simple, Default settings in MGSV implies texture filtering and shadows on medium, everything else on high and volumetric clouds off.
PS4
Textures:Extra High
Motion Blur: High
Lighting: Extra High
Effects: Extra HIgh
Post Proessing; Extra High
Ambient Occlusion: High
DOF: ON
Volumetric Clouds: On
Texture Filtering: Medium
Shadows: Medium
Model Detail: Below Low
1080p, solid 60fps....
Now, I said this is not "console settings" because the xbox does not match that, it has lower filtering, lower effects. (lack of SSS etc..), lower post processing (lower quality MB etc...). When NXgamer weighs in, we will adjust the list above as necessary as he will give a more comprehensive picture as to console settings, but this is what we know thus far as far as consoles go....
The settings Santiago left on Extra High was Model Detail, Textures and Texture filtering. Textures are the same quality on console and PC (Extra High), Filtering is free on PC (does not affect performance) and model detail serves as the biggest disparity between the two. Though I think it's impact is not great. (visually or performance),but the difference is there nonetheless.
As I said to you, the i3/750ti from the video I linked is a higher overclocked card than what DF referenced, so DF's performance would be even lower, much lower still if the card was at stock, which is where all the rage of the i3/750ti began in the first place, now it's got to be overclocked.
Regardless, with these settings, on an overclocked 750ti he could only muster around the low 50's on average. When he approached an outpost and used his binoculars frames stared dropping to the late 40's frequently. When he entered the village/outpost, he was pretty much at 50-47 fps fluctuating. DF's framerate would be lower in comparison.
Again, Santiago, said that he could only get a 60fps lock at 1080p with everything on high and motion blur off. It would be nice if DF presented a video to substantiate their claims, however, there's no doubt that NXgamer has the 750ti setup, so we'll wait on that to know how that setup really does....with evidence of course.
