They're kind of different, in a way. FxAA, if I'm correct, basically makes the entire game image softer, almost fuzzy, in order to keep the video looking smooth. Regular AA makes the image look better, but costs a bit more in performance comparatively.
In other words.FxAA does a decent job while costing little (relative) performance, whereas regular AA can take a bit of a toll.
I came here for nuttin' but instead i got nothin', like I never came.
pickel_weasel_4 posted... So if they work differently, does that mean you should only have 1 or the other one and not both at the same time? How does fxaa compare tp 8x AA?
8xAA is real AA so it will look better than FXAA. FXAA is mostly Anti-Aliasing for consoles, its function is kinda like Edge AA which blurs out edges instead to make jaggies less noticeable, it works great for consoles as its not heavy/demanding works great for people with low-end pc's aswell.
