Ah right, thanksIts just kinda pointless... and more clutter than anything else.
Not only that, you want to be careful about what addon stuff you take from Nvidia, the audio drivers it packages in as default are getting reports of being buggy.
Plus its version of what "optimal" is, isnt always optimal... ive found manually setting my video preferences in games can give me the same quality image but higher framerates...which is half the reason it exists, to try squeeze performance out of your settings.
