"maxing out" is never even a good idea. There's always settings like that kill performance and FPS while offering not too much improvement to the visuals. What's smart it to enable the highest graphics improvement / performance toll ratio settings and disable the lowest graphics improvement / performance toll settings. There are always going to be games you can't max out.
The only purpose of maxing out games it to gain mental satisfaction that you are maxing out games; 5 years ago, we loved maxed out games so why should we consider that graphical quality any less today? It's the machine. It's what the graphics companies want everyone to think. If people just realize that graphics look beautiful on medium even, then there won't be such a dire need for everyone to get max settings!
Think of the future. Max settings today are low settings in some number of years. So why do we even bother thinking max settings look nice at all today? Because in 5 years, when low = 2016 max, we will be thinking, "ugh, I don't want low settings" but if they are the equivalent of max settings today why do we want max settings so bad if we know they are actually low-end? 480p movies look a lot more real than 4K maxed out games still.
Okay my rant is done.
