AF (Anisotropic Filtering) is a texture filtering technique used in most games to enhance the image quality of textures rendered at an oblique viewing angles in the game. It is usually not that costly on the hardware and as such, it is used in almost majority of the games.
Unfortunately, when it comes to the PS4, there have been games that are clearly missing AF settings despite having them on Xbox One. This is a rather strange case as PS4 has a much better hardware than the Xbox One, and if the Xbox One has AF applied in its games, the same should hold true for the PS4.
This issue mostly seems to affect Unreal Engine 3 games on the PS4, as seen in games like Thief, Dying Light, Strider and the recently released Devil May Cry Definitive Edition. Needless to say, AF is something that curiously seems to be missing from PS4 in some of the multiplatform releases on the PS4 and and Xbox One. One such example is below.
Ninja Theory has acknowledged this issue on their Devil May Cry Definitive Edition and confirmed that they are looking into it.
This is something that we're aware of and are looking into RT @JustSlaythe: Awesome Game ! But can you patch in the AF on PS4 ?

Now it seems like Sony is working on making it easier for developers to implement AF in games, as confirmed by comments shared by one of the developers on NeoGAF. While he was under an NDA, he did reveal that they plan to make it easier for the devs, even if it isn’t that ‘difficult’ now.
FYI Sony released a tech note related with AF.
Well basically (I don’t want to enter in any specifics) it reminds devs how to make it properly and a future update to make it “easier” (it is not that it is “difficult” now at all).
No, it is not that complicated.
I really don’t know where the issue comes from to be honest (since you can use AF) but I think Sony knows about the “problem” and maybe they reacted to show devs how to “fix it” or to clarify if it is some misunderstanding about the process.
Hopefully this means that future PS4 games can no longer lag behind in term of AF in multiplatform games.
