The "PC Master Race" meme has some merits. Gamers who care about a title, given some technical knowledge, will often make it look better than the developers intended. Skyrim and Grand Theft Auto IV can both look better than most next-gen releases. Watch Dogs is peculiar, though, because it just came out.

TheWorse Mod for Watch_Dogs apparently started as an attempt to restore the bloom effects from the game's E3 2012 trailer. Since then, TheWorse has improved performance, reduced stuttering, and improved many other effects (such as adding bokeh DOF blurring). The end result is quite pleasing to the eye.
Check out the Guru3d thread as it develops. The versions seem to by arriving frequently.
