Edit: It seems with the help of GAF and Reddit, I've single-handedly brought down Guru3D. Sorry.
Edit 2: Alternate download link - 'TheWorseMod 0.8'.
Edit 3: Another Guru3D user - 'Kadzait24' - released a similar modification first, but then proceeded to be an asshole about the whole thing and ended up getting his thread locked. TheWorse came up with his mod (seemingly independent from Kadzait24's work) which enabled a hell of a lot more graphical features, and he's been a gentlemen to anyone enquiring in his respective thread since he posted it.
TL;DR: TheWorse did a better job, Kadzait24's butthurt and now doing the best he can to troll everyone involved.
Edit 4: Wait! There's more! See below quote.
To quote CyberPunked from the PC performance thread...

Included in the mod (v0.6... not all available yet!):
Oh Ubi.
Downgrade if old.

Oh there's more as well. Not only did they put in graphics settings just for E3 and then forget to delete them from the final game, there are also animations:

Thats the "hands up" animation from aiden before he does the blackout.
This is a joke that keeps on giving.
But its great for us because it means we will be able to actually play the game as it was originally shown. Great work by TheWorse and all the other guys who are digging into this. This is a more significant breakthrough than the graphics settings IMO as it means there will be huge modding potential for the game now provided Ubi doesn't stop it happening with their next patch. But there are always ways around these things as there was with GTA IV

Has made massive discoveries/improvements. He has discovered that almost all of the shaders and improvements seen in 2012 and 2013 are still in the game files, such as the e3 2012 explosions. For now he has managed to implement dynamic shadows from headlights, the increased rain density, increased NPC density, as well as 2012 e3 bloom and lens flare.
When he manages to unpack certain files, he will be able to activate everything, such as POMs, etc.
