There seems to be a major problem with NV's default settings in the control panel. Under default, it's supposed to "Let Application Decide" on AF. Yet it overrides in-game settings to **** quality for texture filtering.
It started with a guy on OCUK who benched Titan X & Fury X, people noticed worse IQ on Titan X:

A full PNG comparison screenshot with NV on default driver setting vs forced on Quality: http://i.imgur.com/0UzUR3A.jpg
There is a significant performance (10% perf hit) difference to leaving it on default and forcing it to Quality (to match AMD's default image quality).
A lot of review sites don't touch it, they leave it on default, as per [H]: http://hardforum.com/showpost.php?p=1041709145&postcount=81
One reason I don't think it's a recent bug, is because its been happening for a long time, yet its undisclosed by review sites, they don't even do IQ testings these days.
From a few years ago, PCPer's video to compare performance. You can see AF is rubbish on NV.

Basically its either a bug where the default settings are supposed to let the app decide on quality, so when you set in-game to Ultra you expect it to be Ultra, but its actually running Low. If review sites test with settings on default, it leads to an inflated benchmark numbers for nvidia GPUs.
This kind of cheating is so early 2000s (http://www.geek.com/games/futuremark-confirms-nvidia-is-cheating-in-benchmark-553361/ ), as a gamer, I would have thought it no longer happens!

Changing in Nvidia control panel to prefer max quality actually fixes this "bug" and stops Nvidia quality degradation

Wonder if Nvidia will admit this in a similar way to the Kepler gimp where they also claim its another "Driver bug"
