I never bother with auto optimization tools for gaming. The closest to that I come is sourcing graphics settings guides that explain and show differences in settings and give you a clear idea how much performance impact each has.
The thing is, avid gamers have their own opinions on what settings are useful and which ones they want to avoid. For instance a lot of players don't want any motion blur. All those optimization tools are is an aggregate of settings users have chosen that Nvidia and AMD use as a base for so called "optimization". The problem is you have zero idea what features are going to be turned on/off, lowered or raised, unless you examine all your settings carefully before and after using it, and by then, you've done half the work of choosing your own.
Years ago when the guy that ran the TweakGuides.com site was doing graphics settings guides, I always referred to his site, because he also gave advanced info on all the available console commands for the game as far as how changing their values affects the look and performance of the game. Nowadays the next best thing I find, since Nvidia doesn't tend to write the GeForce Graphics Settings Guides anymore, is Digital Foundry's guides done by Alex Battaglia, which you can find on YouTube.
Mind you I didn't have a plethora of knowledge on graphical effects and settings when I first started doing this, but after reading through (or now watching) such guides, you gain a lot of info about how to setup your game, according to how YOU like it.
