I kind of disagree, I've been able to notice AF working in just about every 3D based game I play, even helps in some 2D games as well.

Uh it's kind of impossible for anisotropic filtering to help in 2d games...

If you think it does then you are either looking at a 2d/3d combo game(e.g. Ar tonelico II which uses sprites for characters/objects but simple 3d for the world those sprites exist in) or you don't know what you are looking for.

The purpose of AF is to increase the quality of textures that are both far from the camera and at an oblique angle to the camera. Like this:

It's impossible for it to help in 2d games because in true 2d games nothing can be oblique to the camera.

I know what AF is =), hehehe.

It makes a noticeable improvement in Atelier Iris: Eternal Mana combat situations. Turning AF on reduces all shimmering when the camera is moving and panning around =).

About Anisotropic Filtering in PCSX2, you need it to not be forced in the drivers. With Nvidia Inspector, I made a profile for PCSX2 and set it to "Application-controlled".

If it's forced, AF doesn't work at all, but it works fine with the GSdx options.

AF is not force in nvidia global profile and as far as i can tell AF dont work in 3d games like FFXII there is difference with it on or off on my end there is no diffrence between far off textures vs close with on or off,

But i know last time i actual test AF which was when first came out it helped great deal in textures in FFXII and I just tested that and Rogue Galaxy and it dont help either game I went test this with very last SVN build and AF seem to do nothing there too in those games.

So short of i doing somthing wrong or nvidia broke something in drivers 350.12, I dont know

I did some AF Testing for Final Fantasy XII using two different camera angles, I'll link the direct links for the images, since I made them 1080.

you have those label wrong off is really on in all those pictures and on is really off.

Actual after doing this on my end on same camera angel. I get same results though to me on is really off of off is really on

Cause off is crisper textures in the distance and on the textures are blurry

No, his labels are right.

You won't get the same effect you get in PC games as the PS2 games don't use mipmapping. Because of that, the pixelated, ultra sharp textures are the off ones, the more "blurry" (actually just more correct for the size and angle) ones are on.

[tsunami2311]

To me it looks like they are reversed,
GSDX UI
check=off
no check=on

I could be wrong i guess but my eyes tell me other wise, as the Off with 8x select (sharp) looks better then on with 8x selected (blurry)

And AF makes things look sharper not blurry. " saying off is the more pixelate and on make it sharp" make no sense cause putting it on would make those pixelate "textures" sharper not blurry

So i guess it is work even if i think the ui panel is wrong and checked as off and no check as on. and matter of opinion of AF would make something blurrier when on when it should make sharper as turning AF off is what should make thing blurrier.

Then again i not programer nor did i program this and now how ps2 really works as such i uncheck AF in the UI and leave it set @ 8x

No, you aren't understanding how AF works.

Generally in PC games yes - AF on = less blurry, more sharp. That's because PC games use mipmapping - they use smaller, lower quality textures further away from the camera. But at oblique angles, this creates the nasty blurry effect we hate. AF remedies this.

However PS2 games do not use mipmapping(except for a few, and those don't work in hardware). They use the same texture no matter how far away it is from the camera. This creates a too sharp texture that shimmers as you move the camera. AF remedies this.

In most situations the application of AF in a PS2 game is not for the exact same reason as in a PC game. It both improves the quality of textures, but not in the same way.

That said if you prefer the no AF look then you prefer it, and there is nothing wrong with leaving it off.

But if you REALLY want to see if this is a "bug" or not then do this -

Take PCSX2 1.2.1 package which has no AF. Get to a point in the game good for screenshot. Take it. Then take a later build with AF, go to same point and take shots with AF on and off. Then compare them to the 1.2.1 shot and see which matches.

Mhm, main advantage of AF in PCSX2 is fixing shimmering, really annoying stuff when playing a game and textures are shiny and dancing with your camera.

I will test this later when i get some time again to do tests again.

As for the other stuff you said it makes sense the way you said it, but make no sense in how it has the reverse effect on ps2 games. cause even if it using all the same textures at all distance cause ps2 dont use mip it does not change the fact af make textures sharper there for it should make the sharp texture that much more sharper. i know to sharp makes things shimmer though but that stuff rarely ever bother me

I not programer so i not gona pretend to understand it
