And what about other methods like :

FXAA : http://timothylottes.blogspot.be/2011/0 ... eased.html
MLAA : http://software.intel.com/en-us/article ... sing-mlaa/
TXAA soon ?

Because super sampling is really hungry :-P

If you have a Nvidia-card installed just try it yourself, the 300.xx Release drivers allow you to enable FXAA in the driver. In my opinion it works quite decent unless you have very fine structures (fine text like on the symbols in a car is a worst case). And after all it´s nearly for free :)

Yup, FXAA isn't bad, even for filtering slightly noisy stuff (mileage will vary though obviously), and the extremely optimized code is available for download on all platforms.. TXAA is mainly targeted at animations/interactive usage at high framerates, so i guess not that useful here.. MLAA is/was neat, but from my experience, FXAA is more stable nowadays and well tested, too..
Most highend (game-)users tend to use a combination of FXAA and super-sampling nowadays AFAIK, so rendering on a high resolution, FXAAing, then downscaling to screen resolution for crispy results, even during animations..
And then there is also SMAA which i think crytek uses/used a variation off?!
Better you leave here with your head still full of kitty cats and puppy dogs.

Because it seems that traditional techniques (filtering...) does not produce very good results :-(
I work with PRMan on feature films and although we see this problem too when looking at the raw renders, after the compositors have added bloom, lens distortion, film grain etc the problem goes away naturally and it's not something which needs to be managed specifically.
