I disagree
Well for one that picture isn't exactly large, so it's
easier to be mistaken - which I wasn't, I will add.
Post that picture at full resolution and it becomes even more obvious.
That looks far from "real" to me. It looks like a game. (Also, I know Shangrila, so my first thought was "oh, Shangrila")
Further, make someone watch the game being played at full res. and unless you have no clue about video games, there's absolutely no way it'd fool you into thinking it was real/a movie or whatever. Ergo there is still tons of work to be done in the visual department, when it comes to games.
Games are moving towards visual realism, but we're still
miles away. There is still
so much more to be done in the way of real-time graphics that I'm pretty sure I'll be gone by the time anything comes out that will really make it hard to tell if it's a game or the real thing.
I haven't played a game to date which is even teetering on "is this real - or is this a game?!"
Every generation that brings new graphic prowess, is usually heralded as virtually indistinguishable from realism... until the next gen surfaces and you laugh at yourself for thinking that it was even close.
When I first saw Crysis I was like
amazing. Looking at it now... yeah it's still very nice, but not that impressive any more. In a couple of years, it too will just look dated and anybody who reckoned that it looked super life-like will probably find it amusing they did when compared Crysis 2017.
Read real old gaming articles, where you'll find people back then were praising the graphics for looking "amazingly close to the real thing" when to us now, they look nothing like the real thing.
I remember seeing games way-back-when thinking "man that's SO realistic"...
Of course I am talking real-time here as there are architectural renders I've seen that are immensely hard to differentiate from a photo/film.
But I've not played any game that even comes close to me not being able to distinguish it from a film.
On the other hand my father visited me once, and I had my PC running with some game on it and he asked me what film it was.
