Theres another demo from this year?. Im gonna see if i can find it, but if i can't can you post a link to it here?.

it's the same demo, just using a GTX 680 instead of 3x GTX 580 and with some performance tweaks and FXAA instead of MSAA

last year: http://www.youtube.com/watch?v=XgS67BwPfFY

FXAA is an intelligent approach to the aliasing problem, but it has a big problem, blurriness. It works on everything, polygon aliasing, shader aliasing... but it also makes textures blurrier. As all the low frequency pass filters, it kills the high frequency information, and texture sharpness is high frequency information.

I see, so that's the trade off for having better anti aliasing results with less stress for the GPU.


Thanks :D. Using MSAA or FXAA both look great to me and i couldn't really see the difference :D

If you want to know more of FXAA you can read the blog of the guy who developed it:
