That's the biggest problem IMO, power wise, even Nintendo's very latest desktop hardware runs at about the equivalent power of a low spec gaming PC that would run Doom, a 29 year old game nearly, if you're extremely lucky.
It's not a problem though. Again, you REALLY dont need much power with today's games (comparatively). The idea that you do is a myth, and a bad one.
But yeah, most modern games will run on a potato. I mean, ALL of the consoles are weak. All 3 of them. Very weak compared to most PCs. Even my previous PC, which is "missing a few screws", to put it nicely, utterly outpaces the things in every conceivable way. Hell, my previous laptop, which was utter junk, also completely stomps all three of them (and I freaking HATED that thing).
But all three consoles will still run anything without issue despite that comparative "weakness". The only true difference is hardware differences and similar things, and that ends up only affecting internal development... stuff the consumer will never see nor hear about (unless something bugs out, some developers may explain some of the process when that happens).
There was a time, back in the 90s and 2000s, when "power" was at a premium. When consoles were *incredibly* weak, and PCs were complicated... you had to carefully check the required specs of any game you wanted to buy, and it was fairly common that you'd find your machine wasnt powerful enough to handle whatever it was. The installation process for most games was a confusing mess, and having to deal with driver updates was even worse.
That is all in the past. Hell, with PCs, I genuinely dont remember the last time I actually looked at required specs for a game. Nor do I remember the last time I had to manually deal with drivers and such (Steam just does all of that itself). If I had to guess, it was probably at least 10 years ago. And the consoles are the same. There's no real wondering "does this game actually run WELL on this console? Is this the console I should buy it on, due to that?" It's not like the SNES running Star Fox, where you could expect it to go at like 2 frames per hour. Or the N64, with it's infamous "fog", or the Playstation and the crazy amount of "popup". Most games are smooth as butter with no visual issues, unless the developer is awful at their job. You mention something like Doom (the original), but *any* PC... even some craptastic business machine... can run that effortlessly now.
The one exception to all of this is virtual reality. You want that to work, and work PROPERLY, without side effects... you need one hell of a powerful machine. There's a reason my PC's cost was so freakishly high, and that's why. I wouldnt have bothered doing such a thing otherwise. And yes, I'm aware the PS4 has VR, but... let's just say that it has "issues". Anyone into VR will want a Rift, Vive, or some form of WMR (many different brands for that one now). And that also means a beefy PC that can truly handle it, otherwise you get.... problems.
$4500 for a PC. Holy cow. A decent, top of the line gaming rig shouldn't have cost you more then $1000, I know. I build PC's for A living and I'll bet that machine you got is probably only 10% faster( if your lucky) then a $1000 gaming rig. There are professional gamers out there the play for a living and pay about $8000 to max out there machines and they're only getting about 20% more performance then a $1000 rig would do. They can justify that cost because the difference between losing and winning can be several thousands of dollars in prize money. Plus they also get sponsored as well. Anyway's, my point is. If you spend that much money on a gaming rig. Unless you're a professional gamer? You got burned.
Nah, this is all stuff that was gone over VERY carefully. My father is the one that paid for this, and he does not make such purchases lightly. Either everything is fully understood, or whatever it is doesnt get bought. The family's... er.... "financial status"... would not be what it is if he just paid for things without truly researching it.
I also went over it with a variety of developers that I know, since they're all about technical aspects like that... it's what they do, after all. One in particular always builds everything himself, and is *really* into VR, with all the implications that brings.
Not to mention that this was all easily tested with a variety of benchmarking programs. To say that the difference between my $1200 PC (or the recently bought $1500 laptop), and the new one, is massive, would be a monumental understatement. Again, not only was this specifically intended to run full VR *perfectly* at all times no matter what, but gaming is also my core interest. The focus of my existence, if you will. I may not be a "professional" gamer, but I still have good reason to want such power even beyond VR itself. The fact that I do actual development as well as internal testing for a variety of games also adds to it. Professional gaming isnt the only reason someone might want such a thing.
Besides. Even if we had gotten "burned", well... I wont go into detail, but let's just say that $4500 doesnt really put a dent in anything. I doubt I would really need to explain that further to show what I mean by it.
