So, non-gamers are a game-related argument now? My grandmother probably can`t see a diifference....anyone who games somewhat regularly however can and will notice the massive difference immediately in any game faster than...chess.
Go to any gaming forum, even here. There are people that can't really tell the difference between 30 and 60 FPS. 120 and above are a lot more subtle in comparison.
Nothing is "earth shattering" to you, because you need some reason to have a 400$ box not look bad besides a 2k gaming rig.
I don't really care about making one look better than the other. I can get a few 2000 euro gaming PCs per year if I wanted to.
It's more about the value proposition and what is the real result on screen. PC gaming is console gaming with a few "nice to have" elements added. Geometry stays the same, textures are a bit higher resolution but largely the same. The rendering pipeline is mostly the same, with maybe a few extra effects here and there.
I mean, I'm not going to say it isn't nice, but having extra resolution and framerate doesn't turn the experience into something next gen. It's current gen assets, afterall, you have to wait almost until next gen of consoles arrive to see any significant upgrade in graphics rendering on the PC side, otherwise during the generation, you spend 4 times or more of the cost of a console for a few extra trees, a bit further out houses in the distance, shadows look a bit more defined and a bit more detail on the shirts.
Is that worth it? It depends on each person, personally I don't think it's worth it and since it's the same assets and rendering pipeline, it's silly to call that next gen, even if it includes RGB and a racing chair.
