It literally takes double the performance to run something at 1080P vs 720P, all else being equal. I would call double the resolution more than "somewhat meaningful." Also from reports the frame rate is also worse on the 720P X1 version.
No, the reports are conssiten - the PS4 version ahs worse perf. How much worse is the only thing in question.
BTW with BF4 not only is it running 56% higher resolution on PS4 but also at a consistently higher frame rate (according to DF, 2-4fps during cut scenes and "well above that" during gameplay). Is that a meaningful performance gap to you? Curious.
No. After watching the two in all the videos I've seen, and in the pic comparisons - the difference between BF4 on X1 and PS4 is not meaningful. The X1 version's color vibrancy and sharper textures is more noticable to the layman than the more pronounced aliasing is due to X1's lower reoslution... so any time a layman can look at both and not tell the difference, or actually arguably prefer the suposed inferior version, yeah, that's not meaningful. Not at all.
How do you get "par for the course" when so far this game looks like the exception? DF has not done an analysis on this yet but let's just assume NFS is equal. So we have three multiplatform games that have been compared, only one of which is equal so far. That would mean this title would be the exception by definition.
We just disagree. See, you're looking at the numbers and seeing a clear vioctory for the PS4. I'm looking at the actual gameplay footage, and there just isn't a meaningful edge - not on ANY of the titles which have been compared.
Therefore, I'm not only perfectly rational to say this is par for the course, but I'm correct in saying so.
Next up is Assassin's Creed. All of the same insiders who got the BF4 and COD delta right are saying that the X1 version also looks worse and runs less than 1080P, and given that Ubi Soft continues to only show off the PS4 version I'm guessing Ubi Soft is the next "lazy dev."
If the delta is what we've seen so far between COD and BF4, it's negligable, and not meaningful at all.
BTW I'm curious about what you think of the latest Forza shots that MS has released. Beyond3D analysis shows that the gameplay is actually 720P but the UI is 1080P. Is that technically a 1080P game?
I haven't seen or heard of this being true, but if the game renders to a 720p back buffer, then obviously that's not a 1080p native title. When I've played Forza 5, it looked like native 1080p to me, but admitedly I didn't do any thorough analysis, and I haven't asked anyone in Turn 10 whether or not it is, but with all the things we've said about it being native 1080p, I'd think that would be disingenuous and misleading if it is in fact rendering native 720p for the primary rendering and rendering 1080p only for the UI.
...but this is exactly the point. When a game has true 1080p UI, and a nicely rendered 720p image with anti-aliasing, etc. and it's upscaled super well to 1080p - then the lines between 720p and 1080p begin to soften... and at that point, if you can't tell with your naked eye, does it matter? Of course not... and that's the advantage of having multiple planes to render to which have their own unique hardware scalers associated with each.
