When Watch Dog's first trailer was released at E3 2012, gamers and critics were taken over by the game's unprecedented graphics quality. Unfortunately, Ubisoft was not able to deliver that quality in the final version of the game which ended up with good-but-far-less-impressive visuals.
Good news for our hardcore PC gamers, a modder named "The Worse" has been able to locate the original visual effects in the game's files and use them to "restore" that E3 2012 graphics quality.
The restored effects enhance fog, bloom, lighting, shadows, reflections and rain among others. The Worse released a few screenshots from the enhanced PC version and they are all available conveniently in the gallery.
