thanx sirpauly. I just only can see this as something good, i mean for now. In these console port days. PC Gaming isnt the same, its just fact. I know there is better AA but why be bothered by an attempt that will only give us better IQ. Developers are not as concerned with the PC by itself and consoles arent capable of the more taxing AA no matter how good it looks.

I think its just a result based on the facts. Nvidia is trying to find a solution that gives us better IQ when the developers are failing. Whats bad is how close to PCs consoles are. The next one will still be sold as a separate kind of system that in a few yrs, once again, will be holding graphics back.

Here is a video discussing FXAA towards the end:

Both SRAA and FXAA look horribly blurry to me in that DICE presentation and still don't match MSAA. This isn't why I purchase high end graphics cards. If I wanted that sort of output I'd use a GT210 or a software renderer.

Here is more data on something I've learned, thanks to FiveFeet8,

Quote:

Such a technique is quite a novelty in the video game industry and it’s very likely Crytek will
release improved versions as it has potential to also be merged with different techniques -
for example, it’s currently also combined with Nvidia’s FXAA in “Extreme” spec, in order to
improve quality further with sub-pixel accuracy results from post MSAA.

Antialiasing - FXAA

FXAA is a fast shader-based post-processing technique that can be applied to any program, including those which do not support other forms of hardware-based antialiasing. FXAA can be used in conjunction with other antialiasing settings to improve overall image quality. Note that enabling this setting globally may affect all programs rendered on the GPU, including video players and the Windows desktop.

• Turn FXAA on to improve image quality with a lesser performance impact than other antialiasing settings.

• Turn FXAA off if you notice artifacts or dithering around the edges of objects, particularly around text.

This is stated in the nVidia control panel.

This was shared by jackfuste over at Rage3d:

This is a really nice find because it looks like for sure that FXAA will be a feature for every application, including DirectX, and certainly wonderful for flexibility for titles with no AA capability and to use in conjunction with other more traditional methods.

Does this mean it is working in 257.33 for things other than OpenGL (it only worked for OpenGL in 275.27)?

Not yet! So far, it only works in OpenGL but looking forward to Direct3d. The data offered by Jack was welcomed for me because the wording said all programs.

Hard OCP article on FXAA and FEAR 3.

Note that it works on AMD video cards as well as nvidia's own cards. MLAA works on on AMD cards. Guess which one developers will be more likely to make use of as a reesult of that (hint: not MLAA).

Looks like the FEAR 3 devs did a better job of integrating it into their engine than the likes of crytek (Crysis 2) and (surprisingly) Duke Nukem Forever. I'll still use MSAA where I can. Would love a GTA IV patch and a Gothic 3 patch with FXAA integrated though.

Thanks for sharing!

This is another post so one can enable the FXAA setting in the Control Panel but it still only offers OpenGL support up to this point:

i think i will wait until it is generally available like MLAA is in CCC

Some games already use it - like Duke Nukem Forever - it is offered as an in-game setting. In some cases, it looks better than with MSAA - but not always. Actually, DNF is a game that looks best in 3D Vision with Post processing off and FXAA on
- and at 5760x1080
