PS4 had 8xAF, xbox one "a reduction in texture filtering"

benevolent sexism
The one that was contrary to expectations, obviously. Everything being as it should be is not news and not something to discuss.

No it doesn't. Stop saying this because it's bullshit. All AF fetches are perfectly cached by texture caches these days. This is why it's nearly free even on a lowest end GPUs on PC.
As for why that is happening I would assume that it's a combination of API translation issues with bad QA on Sony's part.

Not to derail or make it seem like a problem, but what was your first PC? AF was huge hit to performance even on fairly modern GPUs, such as Geforce 7800GT (same GPU that PS3 has), I am sure even 8800GTX had tangible difference between AFx4/x8/x16.

I wasn't sure what AF was, but now I'm curious as to why not all PS4 games are using it for crisper textures?

Sony QA doesn't touch this kind of stuff. It's purely up to the developers. No one else cares, most people don't know what AF is or does.
Lol what. The 8800Gt handled AF without breaking a sweat, at least from my experience.

Not really. The last PC GPU which did have a big performance hit with AF was from NV3x line (GeForce FX series). NV4x (6x00/7x00 series) handled AF quite nicely, G8x (8x00/9x00/2x0) and up had it nearly free.
Sure they does. Each title going on PS4 goes through SCE QA prior to going "gold". This is a regular console procedure which was put in place to make sure that the game at least works on the console - which is in platform holder's interest as you understand.

The odd thing is that, the less powerful platform in xb1, has AF in games where the PS4 does not. THat is kinda.. odd.
Actually BF4 has the same level of AF on consoles, it is just the xb1 version is so low res that distant detail is blown out in a mess of pixels much more quickly.

Well perhaps the question should be why AF is more difficult to implement on PS4 than XBO then? After all PS4 is supposedly the easier system to develop for.
Honestly? It's obvious. This isn't 'Spot The Difference'.
Textures get blurry in the distance when viewed from an angle. It's a good way to completely shit on a games art assets for no apparent reason.

7900GTX. The PS3 GPU was more along the lines of a 7600GT. Nevertheless, PS4 should by all means be able to do it.

i think the only game that has 16xAF is TLOUR?
Well to his credit, he may have seen the text in the images, your post could easily have been taken as you're making a joke while also asking what to look for.

I bet this is happening because it's the default setting in the hardware/SDK and no developer cares or bothers to change it because they don't even notice it.

PS3 GPU is carbon copy of 7800GT, up to operating frequency, minus 256-bit memory bus.
...Which are required to holder higher-quality textures if they're going to perform higher-quality AF.
We had this same discussion before, where you claimed that GPUs always read in the highest-quality textures anyway. AMD themselves disagree with this, see this presentation about GCN which says that mipmapping helps in avoiding cache thrashing (slide 69). That wouldn't be the case if GPUs didn't intelligently read in mip levels according to the needs of their filtering!
Developer choice? Why would a developer choose to have it on the XB1 version and not on the PS4 version?
And saying we want to know why there are quite a few AAA games that don't have AF on PS4 but do on XB1 is not denying that there aren't a lot that DO have it. It's just weird enough that there ought to be a reason for it.

Its quite worse than a 7800 GT actually, 1/2 ROPs and 1/2 the interface is quite a big deal.
Really? I thought that hasn't been an issue since like 2010. Crysis was the only game I recall having that issue.
Core clock is 500MHz. GDDR3 clock is 650MHz (1300).
It was actually a 24PS/8VS/8ROP part.
Smoke clouds look best with 4 instead of 16. I think 4 is best.
EDIT: OOOOH THE FLOOR

This comes off like thread whining from someone that didn't have to comment at all. If you have no interest in technical discussion, why are you here?

Indeed, but with half the bus width... it still does not approach the bandwidth of a 7800GT.
Concern trolling? Because you don't notice AF like at all?
How? Nobody is saying the PS4 can't do AF, it's just curious that the console with a more powerful GPU and more memory bandwidth tends to not have it, or use a worse implementation of it than its weaker counterpart, in a handful of high profile multiplatform games.

Yeah, and it already had only minor performance costs on ATi's R300 (Radeon 9x00) in 2002 (the filtering quality was a bit reduced though - even more so on the previous R200). I actually played all my PC games with 16x AF since then.
Still, it needs to be stressed that AF isn't free and will never be free, even if it may look like it on a PC where most games are apparently bottlenecked by other fators. As Durante already stated most console devs deliberately use low AF factors in order to save some performance for other stuff (and I also think that it is a bad choice).

I keep reading about squeezing out better performance when not using AF in consoles but is it really that big of an impact? Nearly every pc hardware I've owned has been able to use AF with little to no performance penalty. I've owned a couple of nvidia gpus like the gtx 275, 8800 gts (320mb one), a vanilla 6600, and a 4200ti, all with matching cpus that were nothing special and I don't remember AF being a performance hog with any of them
Per DF, it doesn't sound like AF is quite as trivial as most of us believe. It's still speculation on their part, but interesting nonetheless.

Your post is very concerning. Tbh. There's obviously a demand to get it fixed, why be concerned about it?tbh

Everything may go through Sony to be certified, but unless there is a requirement that games use at least nx filtering it doesn't matter. It has nothing to do with QA.
Ehhhhhhh, 8 and 16 aren't too different visually. No shit it is 16 on PC IF THEY TURN IT TO THAT
This means nothing about how taxing AF is. They just assume that anything under 16 means they lowered it, which would be false no matter what.

People who ask why is it a big deal or say they can hardly tell the difference are blowing my mind.
Sorry that you're blind, but for a lot of us it's extremely noticeable and a huge eyesore.
I didn't know this was a thing before this thread (don't have a PS4).

Report me for trolling ND/TLoU2 threads
glad someone made this thread to spread the awareness however awareness can only do so much, everyone if you want answers take this to social media like twitter and facebook and ask the devs straight up. If they cant give you an answer it means they just didnt incorporate it for some reason. Some articles posted here says ps4 can support up to x16, so then we know where the real problem lies.

Well, it's a bit tricky as RSX could still access XDR.
