Some of you are hilarious with the massive hyperbole regarding this. It's over! The game is junk! Unplayable!
Give me a break.
As for this patch, it seems to have made the softness a bit better in some areas while other areas don't seem to be changed. I do not believe it is placebo and feel if Digital Foundry tests it that they will see it has improved a bit. The main difference seems to be in close to medium foliage and objects as there seems to be more detail and depth. If it's not a ps4 pro change then maybe it is some overall graphical change...maybe they tweaked the DoF in the game. All I know is there is more depth and separation between Arthur and the world and between things like separate trees and it looks better than it did last night when I was playing.
As for blur while moving the camera, that seems to mainly be the game running at 30fps and Rockstar throwing in default motion blur....it's probably mainly the game running at 30fps.
While I don't doubt it can be tweaked a bit more, some of you seem to think Rockstar should be able to create magic with how this game should look on the PS4 Pro and acting like it should be equivalent to how a top of the line gpu could make it look. Comparing it to how other games that have far less foliage and detail is silly because it's obviously going to be easier to make something be sharper with less objects to render. No other game comes anywhere close to this in terms of foliage and detail so something has to give with the nothing special hardware of the PS4 Pro.
I've seen some say the game looks better at 1080p and I don't agree with that at all. Yes, it did seem to be a bit sharper in spots but the draw distance is quite a bit worse (so many low quality textures used at a medium distance that makes it distracting until you get near them) and the jaggies are pretty bad. With the Pro version, the draw distance is much improved with higher quality textures at that medium to far distance. I'll take a bit of added softness over objects 60 feet away object being very low quality and standing out because of how low quality they are.
