"As you may notice in our screengrabs, the actual results on PS4 lack the corresponding level of crystal clarity we'd expect of such a significant resolution boost. This should surely be a home run for Sony's console, but what is likely to be a software-based upscale to 1080p delivers less-than-stellar returns, and for better or worse leaves the Xbox One with an often crisper looking, albeit much more aliased image."

"The soft blur on PS4 comes across as a missed opportunity given the extra leg-work needed by the PS4's troves of GDDR5 RAM and GPU compute units to hit this 1600x900 mark."

Also it is visible on the screenshots posted by DF. 

There are two reasons for that:

1. The anti-aliasing makes pictures blurry. It can be more or less blurry depemding on the method, but it just does it, because you can't hide jaggies without some "smearing of tke lines".

2. XBox One BF4 uses a heavy sharpening and high conrast setting in the scaler settings to try and hide the lower resolution. Many folks perceive XBox One still images as "looks better than PS4", even though it is lower resolution. (This has physiological reasons I explained in another thread). The downside of this setting is visible jaggies, halos and other irritating artefacts in moving images. You get what you pay for.

...yeah...this is a feature of every modern AMD APU, this was expected...

Digital Foundry fucked up in their write up about Battlefield 4 (they blamed the upscaler if I remember correctly, because the PS3 only had a software upscaling solution and they just assumed that would be the case for the PS4 as well)

...just goes to show that their word shouldn´t be taken as gospel

We will need to wait the final review because the DF pictures are jokes.

Not that it'll be using it often, har har har.

In the past DF proved that their face-offs where accurate.

Good, there's hoping on some nice results with DVD upscaling. DVDs on the PS3 looked crap, even my definitely not top of the super DVD player with an hdmi out, outputed better image.

That didn't change these prictures are jokes.

Here how BF4 looks on PS4... MP... SP looks better.

But the XOne is supposed to have the same FXAA method of PS4's and the textures on XOne are the same (minus the sharpening effect) thant PC's and PS4's.

Ignoring the resolution and the sharper look, XOne textures have as much details as PC's. But PS4's loose details. it does. I even saw on neogaf a PC upscaled 900p to 1080p screenshot of BF4 with FXAA applied and textures (and the whole scene) looked sharper than PS4's and looked like Xone's.

I really notice blur on videogames. The best image (IMO) is a native one with zero Post effect blur. Developpers should not even add FXAA  on an already blurred upscaled image. But here on PS4 it is too much. Upscaling + FXAA + additionnal blur they really pushed it too far. And FXAA doesn't even detect edges but detect high contrasted subpixels anyway. I would prefere MLAA which really detect edges. The MLAA on some PS3 games was really awesome. That is the future of antialiasing, removing ONLY edges, not sub-pixels details.

I am currently playing Metroid prime on Wii at 480p. There is no AA on this game. And the upscaling my TV operates is already too much, I found the game too blurry. In fact Post process AA removes 5% of defaults on any image but adds 100% blur on it.

The PS4 Battlefield 4 is 900p upscaled, while the Xbone version 720p upscaled. The upscaling is done by the GPU, meaning hardware, in both systems. The first DF article botched the captures and they concluded that PS4 is using software for upscaling, which is generally inferior because it also uses system resources. Of course, this was wrong. They later published another article due to backlash and said that the PS4 has the  significantly sharper, crisper, and therefore better image. Xbox seems to have a sharpening filter applied to compensate, which causes a lot of jaggies.
