DICE said they'll fix the SSAO on the X1, hopefully they do something about the PS4 blur, right now the X1 build share the same asset as the PC build.

 

[Brad Grenz]

I would be weary of any images coming from gaf they are altering the images in Photoshop
and are blurring one version and sharpening the other they are also changing the color depth of one version to a lower bit depth.

None of the images you quoted have been modified. They are exactly what DF captured.

 

[DrJay24]

Does it actually look better? Or is it better because certain technical boxes were checked that support a theory of superiority? The only real difference I noted was in edge aliasing that I wouldn't have noticed without the on-screen magnifying glass...

Did you anything from anyone who was there and played it? It is unanimous, period. Objectively speaking, 50% more pixels is a lot and it isn't like they took other effects out. I'm getting dizzy from all this spin and misinformation.

 

[taisui]

LIke I said, DF pointed out that X1 is lower rez, missing SSAO, more jaggies, and worse fps, yet there are few that feel the need to photoshop the better PS4 version for "simulation" in comparison GIFs, who's spinning whom here...

 

[patsu]

Well, we can't really stop them from asking questions and experimenting right ? They may want to understand the differences between the 2 approaches. Photoshopping the images to recreate the final image is one way for them to express their view, or prove their point. Whether they are right or wrong, we will probably know more when the game is released. Not far off now !

 

[taisui]

I just find it curious that the X1 version has the same asset as the PC version, while the PS4 does not, perhaps the build is behind which might explain the blur.

 

[patsu]

People are saying some videos don't exhibit the blurring issue. So who knows !?

Since we don't have the game or the source code, all we can do is just wait and see.

It's a minor resolution difference. The only thing I see, is how a herd mentality turns a forum known for meaningful discourse into an echo chamber of nonsense.

 

[RudeCurve]

Looks damn good to me.

It's not the first time B3Ders went gaga over resolution differences (Remember all those pixel counting ?). It's been the same since who knows how long ago.

EDIT: From a technical standpoint, people may want to appreciate what's under the hood. We even have a thread listing native resolution of all the PS360 games somewhere on this forum.

EDIT 2: Here ! Resolution and AA type. Nextgen can probably add framerate and "supports 3D" columns.

These are 30fps captures though.

Does anyone know how these capture devices handle the 60fps input at 30fps? Does it skip a frame or try to blur 2 together?

 

[RenegadeRocks]

I want DICE to delay both versions and get rid of that damn aliasing ! A blemish on such a good game. Yes, it is lesser on the PS4 mp footage, but its still there and noticeable. They had considered delaying it, didn't they? They should have.

As for comparisons, if DF comaprison is all messed up , then we are just wasting time as youtube videos do not have the quality to compare what ppl are discussing. We can only take the word of ppl who have played both at the review event while we wait for Gamersyde to get footage from retail versions.

 

[patsu]

Yes, would be interesting to ask what caused them to consider a delay. ^_^

I asked repi about the PS4 blur and X1 post sharpening on twitter: No reply ! He is a EA bot now

I don't think they can handle it.

The raw format is surely 60 fps and they reprocess it to make it 30fps.

Youtube also can only handle 30fps so whatever you feed into it will be downgraded there.

The processing you can either choose to skip or blend or whatever you want.

I wouldn't exactly say 720p and 900p is a small difference...

Here's a picture to illustrate how much they actually differ.

720p=921600 pixels
900p=1440000 pixels
Difference=518400 pixels

% increase over 720p = 56.25%
% decrease over 900p = 36%

So what we're seeing here is PS4 pushing 56% more pixels, having SSAO AND managing better frame rates.

I remember we had a discussion before where we were saying 50% more flops doesn't translate into 50% more performance. I guess BF4 completely slapped that argument in the face.

 

[Inuhanyou]

Killzone's AA looks nice and clean...i wonder if Guerilla is using that TMAA solution Sony was working on...could DICE use that?

If it becomes a trend over the next 2 years or so, then I'll agree. But one game developed for 5 platforms, with unfinished next-gen tools and probably less time for specific optimizations (of which I'd guess X1 would've benefit the most from) I'd say its a bit too early for damning conclusions.

At least DICE prioritized framerate over resolution in a shooter. Good call IMhO.

Higher native res (1080p) could also be a big factor for Killzone. But yeah whatever that post AA in PS4's BF4 is not very convincing, hope it also comes with a switch on/off option as in PS3's version.

That seems unfair - this is the busiest of times for the DICE team! If he has a family, his kids are probably forgetting what he looks like ...

COD Ghosts difference is even bigger 720p vs 1080p and who knows what graphics setting they're at. But like you said it is too early to tell, would wait for a true next gen multiplat like The Witcher 3 for a better comparison.
