Eh. I actually don't think the downgraded graphics in the GAF GIF look TOO bad taken on their own.
To my eye, the texture downgrade would probably be fine. Watch Dogs' primary art style was the "modernized noir" lighting. Noir lighting made perfect sense for the story and without it, the visuals just look bland. Not bad, but bland.
And it doesn't help that the car itself is now a heinous shade of orange.
I don't miss the texture resolution, but I do miss the lighting physics and, by extension, some of the mirror effects. I expect hardware concerns are probably an issue, but my gut says a lesser reason for the downgrade is that early beta testers said the noir lighting was so dark it was unplayable.
