I didn't know that, but I haven't bean comparing or taking screenshots. I was comparing the settings in game as you change them. Look at the interiors with fxaa turned on and then look at the same interiors with msaa turned on and you'll see how well fxaa removes interior aliasing and shimmering. Using radeonpro and sweetfx forcing smaa only slightly removes diagonal aliasing (hardly noticeable) whereas forcing fxaa blurs the image while hardly removing any aliasing. The same blur occurs when you force fxaa through nvidia control panel.
