Xbox One X is running at twice as much resolution as PS4 Pro. Yes, they clearly favored PS4 Pro.
And yes, this must be the first time we see 1080p on PS4 and 900p on One S. That had never happened before. Ever. It's not like we've seen the same a thousand times at all.
The difference is exactly the same we saw in Sekiro: 900p on One S, 1080p on PS4, 1800 checkerboard on PS4 Pro and native 1800p on One X.
No and no.
XBO X on ELDER is running at a noticeable lower average resolution and framerate than on Sekiro compared to PRO.
The 1800p on XBO X in this case is only when you look at the sky. They use dynamic resolution that goes down to 1530p, in Sekiro was 1800p lock. There are never double the pixels as if it happened in Sekiro.
But it is also that in the average framerate there is more difference despite the cut in resolution. Not to mention that on Sekiro even XBO X had better shadows.
Then NO, it is not the difference between XBO vs PS4 either.
In Sekiro it was reduced to only 900p vs 1080p. In Elder you have that plus huge cuts in vegetation, shadows, AO, AF, half fps on enemies....and lower average framerate.
That is, it is not the same as what was seen in Sekiro like you said, not even close but there is a negative evolution in the XBox platforms optimization.
Not to mention more details and indications that clearly indicate which platforms (at least right now) are one step ahead in attention and optimization such as loading times. Which is another example that the xbox versions have reverted in attention and optimization compared to what was seen in Sekiro.
PS.This talking about the beta of course, we will see in the final game.....
