Try Watch Dogs 2 with all of its lines and buildings. Without AA the game looks utter SHIT at 1080p FULL ULTRA on PC.
It's not until you apply 2xTXAA that the image is decent.
Downsampling from 4K in WD2 is basically impossible with my rig but it looks amazing with a little SMAA. Downsampling is immediately noticeable for anyone with eyes IMO. I don't see how one could not possibly see it.
Of course if the game already has MSAA or something you might not notice it as much. But a lot of games these days have tons of shimmering and aliasing on sub-pixel stuff.
