When I see friends and family members, who are the complete opposite of being tech-savvy, installing things without care, unchecking toolbar options and use software that is supposed to 'speed boost' your PC I understand where that attitude of 'it's too much tinkering' comes from. It's not hard, like one posted on the first page, like cooking or car mechanics. But they haven't been there, haven't done that. It's some kind of witchcraft for some people and this won't happen on a console.
You also have an 'OS' or user interface where you work EVERYTHING from. On PC you have the first layer which is Windows. Then you have, depending on the game Steam, Origin, Uplay or even another layer, another separate launcher. Damn, many games still today won't start with your monitor's native resolution. And for many of my friends and family members don't know anything about resolution, they heard the term full HD and don't even know it's 1920x1080/1200, it really can be a problem to go to the options menu. Why should they if they don't know it from console games where your typical only visual/graphic option is brightness. So they play and wonder in one case about shitty graphics and in another case about bad performance.
For us, using forums like these it's basic stuff like common sense. For many it is not.
With steam and Nvidia auto updating many things it definitely got easier and more convenient but for plug in and play people it's still too much. Because then you have Windows that screws things up from time to time and you have to solve that first in order play further (multi monitor support is still shit these days). Sometimes things just don't work, most of the time due to the user. Options give opportunities and since most people won't use a PC SOLEY for gaming but browsing, porn, shopping, installing stuff and so on, problems will occur.
Sometimes I really appreciate the plain user interface of my PS4 and have everything 'out of one hand'. But then I can't even take a screenshot from a Netflix show or Blu-ray movie I'm looking and I start to love my PC and gaming there again.
