Neo, I would strongly recommend reopening as this would be a very nice filter to have. The PCSX2 guys did it here and it was quite the popular commit:

http://code.google.com/p/pcsx2/source/detail?r=4828

Basically, its a new dealias filter without the speed hit of real AA. Great, for native resolutions also!

A couple quotes from people in the comment thread:
"The thing with FXAA is that it's simpler to implement because it's a shader process, and that it's platform agnostic with almost no performance hit.
The key point here is performance, and MLAA tends to blur all the details along with the fps down."

"FXAA is a shader which gets adapted differently by each developer when FXAA is integrated into a title. The developer has full control over the trade-off between sharpness, reduction of aliasing, and performance."

wespipes: This issue was closed largely because of the way that the feature request was made. If you want us to consider something to add to dolphin, then don't just put a link to some forum where users are naively discussing something that they don't understand. Provide more detailed and useful information to developers. We do a lot of work and research to develop dolphin. It isn't a lot to ask that someone who wants to request a feature do a small amount. I did a Google search on FXAA and found much more useful information than that useless forum linked to above. For example: http://www.geeks3d.com/20110405/fxaa-fast-approximate-anti-aliasing-demo-glsl-opengl-test-radeon-geforce/

Maybe here there will be some usefull information?
