wow... this has to be one of the most incorrect things i've ever read. quite simply in every way you are wrong. this is not a matter of pride, because i am a pc gamer, its just a matter of fact. here are of few of those facts to explain why current pc owners ARE playing games in "next-gen" style.
first - every single game that comes out for current gen runs at 720 - where as anyone running a pc is running at 1080 (or higher), now this in and of itself doesn't make it "next gen" but considering that one of the big selling points of the new consoles is the fact they can finally do this makes t it was worth mentioning. also running at 60 - 120 fps is also one of the considerations (note that it hasn't been confirmed aside from the COD franchise) of next gen consoles, something we have been doing for years. I know that this not only isn't, but also shouldn't be considered next gen gameplay, so please read on.
second - here is where i tell you why we are in fact and have been for a while experiencing "next gen" gaming. dx11. so, the brunt of the post is about how graphics alone aren't enough to constitute "next gen" which i guess to be fair is one opinion. however for the last few years all games on consoles have been running in dx9. that not only means that they have a lower graphic capability, but that they actually don't have the HARDWARE to do the things that game developers ARE putting in games today. a brilliant example of a few of these things can be seen by searching for the DX11 patch for crysis 2. go on i'll wait...... now, those things are hardware specific and drastically change the visuals of the game.
third - continuing on there are things like tessellation which will be added to next gen consoles isn't currently available is something we've seen in many titles. there are also a few things recently to come out like global illumination in hitman absolution, also something that can't be done on current gen. these things coupled with things like increased draw distance or even AA still can't be achieved on current gen and still change how immersive an experience in a game can be. ex. skyrim texture pop ins can be greatly reduced leading to a much cleaner experience. as for the last thing i'll mention, go check out phys-x something thats been around for a while an incorporated into older and newer games alike, something that doesn't change anything visual but is actually adding to the game itself.
finally i would like to add to anyone who could stomach this entire comment is that i am not one of those, "i am so superior because i own a pc" i also own a console and have enjoyed quite a few games on it. the fact is that saying that somehow better visuals aren't considered next gen, and that gameplay is, well this just isn't true. the vast selling point of a new console is what its capable of visually, and whether its done though hardware or software that is what most of it comes down to. to say that a COD game somehow is somehow next gen coming out on a new console is ridiculous if it looked exactly like the last one. most games will play exactly the same as previous games and only be enhanced visually, so in turn the point your making not only doesn't make any since its just plain wrong.
