this is what they say in the video
Ultra Street Fighter 4 has considerably diminished image quality on PS4 compared to PC, specifically in terms of a lack of anti-aliasing and anisotropic texture filtering. 2D elements are badly upscaled from a lower resolution, rather than using the native PC assets.
There are also colour balance issues and transparency effects are rendered in a lower resolution on PS4. In motion, the game looks mostly OK and AA/AF issues tend to be obscured by the fast motion and post-processing effects, but regardless, this should have been a perfect port - and it's not.
read the stuff they are writing and then watch the video. Its unbelievble how much people give them credit without making own comparison and looking at least at the Videos and images.
The PS4 version looks identical to the PC version pretty much. And before you guys come with video compressions as an argument, i say who cares. If a 1080p video cant show a difference in the graphics it cant be that much different, so stop with these excuses.
I mean these guys from Digital foundry can say anything without held accountable ? Is that now the new thing to say or to apply? Having better colors than version A therefor Version A looks like shit? And the perception of colors is a matter of taste to begin with.
And if thats not enough it can be argued that the PS4 version looks even better because it has graphics effects who are missing from the PC version entirely, the PC version version is built around the Xbox 360 version while PS3 version added graphics effects which the PS4 is built around. I show you examples from their own Digital foundry page they are showing but keep in mind that things like that never count in their final verdict where they are trashing the PS4 version even if they are showing these differences in their own article.
So what is better? these half matched and mixed arguments of better colors, AA, AF or missing Animation? Animation you will see everytime if you do this or that special move? I mean look at their own page where i took the images you need to search their arguments with a loop and even then i dont see a difference.
Another thing they actually dont want to talk about at all is that the PS4 Version has better Motion Blur effects, here an example from their own Video which they dont mention at all in their article. It looks more realistic obviously
