FXAA - Fast and software antialiasing
-
In principle yes, it should work in almost all games. Keep in mind that since it is a post-processing pass at the end of the image generation, it is not incompatible with "normal" antialiasing, but it can complement it to increase the final quality. In theory it is very similar in image quality to ATI's MLAA, but with better performance and less image distortion.
Graphics with a lot of computing power, but short of bandwidth (most modern ones, whether high-end or low-end) are the ones that can benefit the most from this software.

it looks very good.:). I will try it and comment on the results.. by the way, is it enough to leave the files in the root of the game, right? and in the game options, do we disable antialiasing or is it enough to have everything at the 'top'?
thanks for the contribution -
Well, this is nothing more than a full-screen filter, but it's a filter that takes into account luminance variations to detect high-contrast variations, which is where aliasing usually occurs. It's compatible with normal AA, in fact, it's the trend that, thanks to the freedom given by the enormous computational power of modern graphics, these AA techniques will be implemented in the game engine itself in the future, and we won't have to resort to multisampling, which is nothing more than a brute force approximation, although somewhat optimized after so many years of use. Both methods are compatible, and if your graphics allow it, the result is really good, as they complement each other. FXAA works on alpha textures, like tree leaves, which multisampling doesn't touch, but on polygon edges, especially those with low contrast (background color similar to the polygon), it works worse than multisampling.
The advantage is that, in theory, the performance drop is much lower than 4x multisampling, the supposed equivalent of this method in terms of quality. Moreover, being a first approximation, it can be polished and improved with more complex and more efficient filters. This type of approximation to the problem is being used in consoles due to limitations with normal AA methods, and in engines like UE3 due to the way the image is assembled. Almost all current engines are not immediate (that is, the image is assembled in a very limited number of buffers), but are "deferred", with a very high number of "layers", often even of different resolutions, for different effects such as lighting and shadow calculation, normal maps... The problem with multisampling is that it doesn't affect all those layers, so games like mass effect with multisampling barely reduce aliasing, or it's a very costly technique in terms of performance because you have to apply multisampling layer by layer before assembling the image, and there are even engines incompatible with multisampling, while these techniques are applied in the last step, already assembled image, so they are much more efficient in terms of resources.

It seems that it is **not** always compatible with other forms of AA, if it crashes, try disabling AA from the game/control panel. GTA4 No AA:
FXAA:
As you can see, it improves the quality of the image, at the cost of a little definition.
-
I have tried it with bad company 2 and it seems that something improved the weapon, it smoothens a little and looks more luminous but not much, I will try it in other games to see how it goes.
-
Now that I have a 9600M go 512 MB instead of a go 7600 128 MB I will be able to try it out too. First on the front, MW2 tells me that not a chance, it doesn't even start. I will try Dirt2 next, to see how it goes.
-
Well I don't have much game installed I'll try to see tonight if I have time the brink, and I have an RTS the command and conquer, the mw2 doesn't work for you so that was my next option.
-
Very interesting the example of GTA IV because it is a game that has no way to activate AA.

Well yes it works on MW2, it was my fault for not updating DirectX, which has a clean install of Windows7. The next test, Bioshock, and it seems to work, from what I have read. The funny thing is that this should work in almost all games, including those that do not allow traditional AA. PS: it blurs very slightly, less than ATI's MLAA, and the quality is quite good
-
And how about the performance? Does it improve in heavy games like Metro or Crysis?
-
I don't know, to be honest I haven't tried it. Does anyone dare?
PS: I see it as more useful for games where it's not possible to activate AA, like Bioshock or GTA4, than anything else.
-
well I've tried it and it seems like a good invention, although I'm not completely convinced by the way the image is blurred
-
Fallout 3 nothing, but Oblivion yes. I left GTA4 installed, to see how it goes.

Based on the FXAA software, a new method has emerged, which improves quality with similar performance. Based on a type of AA called SMAA (SMAA: Enhanced Subpixel Morphological Antialiasing) and developed at the University of Zaragoza, this type of AA improves significantly over FXAA in the problem of blurring.
The project page is as follows: mrhaandi's crypto corner: injectSMAA and the installation is the same as in the case of FXAA.

Let's see what they say, I will wait to test everything with bf3 when I have SLI and can play it in ultra, I will put this in.
Thanks and regards. -
Some screenshots for comparison:
Skyrim_NoAA Skyrim_FXAA Skyrim_SMAA
Skyrim2_NoAA Skyrim2_FXAA Skyrim2_SMAA
Battlefield3_NoAA Battlefield3_FXAA Battlefield3_SMAA
MassEffect2_NoAA MassEffect2_FXAA MassEffect2_SMAA
DragonAge2_NoAA DragonAge2_FXAA DragonAge2_SMAA
TheWitcher2_NoAA TheWitcher2_FXAA TheWitcher2_SMAASMAA 1x a little slower in the tests but I think it looks much better than in the case of FXAA.. besides SMAA does not add the extra blur, or at least it is not as blatant as with FXAA..

He probado Skyrim y estoy dándole a The witcher 2. Para hacer tirar The Witcher 2 he tenido que quitar el Bloom y el Hyperrealismo y casi se ve mejor (menos guarreado xD). Con el AA normal tiro bien, he medido con FRAPS en el campamento y no bajo de 30 FPS aunque me ha tocado darle caña a CPU y GPU; no estaría de más probar SMAA.
Por las fotos en Skyrim no noto casi nada pero en The Witcher 2 se nota bastante sin AA. Lo que sí veo similar con el brujo son los 2 tipos de AA.

Se nota mucho en cómo no afecta tanto a la interfaz, no se come tanto las letras, por ejemplo. Para un jugador de MMOs, es mucho más práctico, al respetar mucho más los detalles finos.

REFOTEEEEERRRR!
Pues lo acabo de probar HOY… ya que voy algo lento, el caso es que puse el Crysis 3 (Gracias a Techno) y resulta que no me da para un AA decente
sorpresa la mía, y estaba pensando en comprar un par de Titan para ir tirando porque los viejos inyectors del FXAA no me funcionaban hasta que caí (mas bien google me lo chivó) en que ahora nvidia resulta que lleva puesto el FXAA de serie y he probado con los juegos que tengo (también tengo que instalar metro para probar) pero el bf3 no deja... Pero la leche va genial de rendimiento si señor!, es es lo mismo que un MSAA pero cuando no tira es la mejor opcion. Así que nada agradecimientos a Kynes con 2 años de retraso :risitas:Resultado en crysis 3 que puedo jugar en texturas muy altas y el resto alto... No está mal, mirando estadísticas es el filtro que mejor rendimiento da en este juego.
PD.
Hay forma de activarlo en bf3?, he probado de varias maneras y no va, nada ya ha visto como. -

Bueno, en realidad no está basado en el FXAA el SMAA, como que es anterior a la primera implementación de FXAA (también tiene varias versiones ya el SMAA). De hecho es la primera técnica de postproceso que imita el AA de las vistas de momento, de la misma forma que el MLAA de AMD es anterior al FXAA de nvidia, pero se ha quedado en la inopia y ahora mismo o se usa FXAA o SMAA, con sus distintas versiones más capaces pero también más tragonas.
Creo que fue en títulos como God of War 3 de la PS3 donde se usó entre las primeras veces el SMAA usando para el postproceso a los PSUs del CELL.
