Not sure what you mean by pixel pop the game looks great to me.
Well I mean the game has a lot of detail, object and long draw distance. Which means that many objects are not quite one pixel large and pop in and out on screen (telephone wires are a killer for this in any game).
I would considered it really noticable in BF3.. are you running with Post Process AA (FXAA) enabled? The ingame option smudges the image so maybe its not noticable. Im using the standalone FXAA injector but it doesnt seem to effect all game items.
Found this good explanation here:

Another effect of aliasing is the shimmering, that happens if the character moves in the scene or if the scene itself changes (e.g. waving trees). This shimmering is caused by the movement of the "jaggies". This is especially bad, if you have fine details, like tree branches, which are too small to be correctly drawn at the given resolution. These details tend to "pop in" and "pop out" with every smallest movement, which usually causes a heavy flickering of these structures. This effect is equally apparent with high resolutions (the detailed structure has just to be farther away from the viewer), so increasing the resolution is not really an alternative.
