Targeting 30fps and getting the best visuals on screen is the whole point of console optimization. It's basically why games still look as good as they do on 10-year-old hardware. Sure, UE5 is a multiplatform engine that scales all the way down to mobiles. However, that tech demo was specifically designed to showcase the new next gen features of the engine on ps5 hardware. Unless, of course, you believe streaming 8k movie quality assets and having "unlimited" geometry would also run on a phone without setting it on fire.

Fact remains that you'll need a NVME SSD and a RTX 2070 Super to run that tech demo at 30fps, while any of the games MS has shown so far will likely run fine on a GTX1060 orlower. The difference there is that the tech demo did have that next gen wow factor, while MS is talking about how hard it is to promote their games because people have to feel that 60fps. 

"Xbox boss Phil Spencer has acknowledged that it's been challenging to demonstrate the true leap that the Xbox Series X will provide over the Xbox One, but it appears that could be changing once people are actually able to try out the systems for themselves in longer gameplay sessions. In Reggie's new podcast, Spencer said one of the most defining characteristics of next-gen games is how they "feel" with faster and more stable frame rates. 

It's not possible to demonstrate this with videos, Spencer said. And with physical events canceled or postponed due to COVID-19, Microsoft is facing a new dilemma in trying to communicate the appeal of faster frame rates."

If you think MS have set some kind of timer for cross gen support then fine. You're just forgetting to ask yourself why they're doing it in the first place. It's really no secret what MS is doing here as they've flat out told us months ago. They are focusing on the bulk of the pc gamers, instead of getting into another format war with Sony and Nintendo. Why do you think MS's biggest 1st party studios are now making games like Gears Tactics and likely another Halo Wars? Games that aren't even getting released on consoles. 

PC gamers are they main focus and we don't really know what the average gaming pc will look like 2 years from now. But until Series X like specs are main stream on pc, MS will just be making smaller scale games that'll run fine on mid-range pc's or Xbox One games that run in native 4k/60fps.

Any news about using it as an windows PC?
Plug a mouse/keyboard, install some windows programs (photoshop, dropbox/onedrive/filesystem access, unity3D, programming languages, deep learning software) and do productivity on it?
It seems that it would be far cheaper than a PC with these specs, and if I could just buya single device as a beefy computer for work, and for playing all my library of xbox games , would be a instabuy.

A gaming laptop ran that demo at a steady 1440p and 40+ frames per second. You’re buying into the Epic marketing talk that they do every generation. 

Also Gears Tactics and Flight Sim are coming to console. Halo Wars and Halo Wars 2 came to console. At some point maybe mods will see your posts as something more than coincidental ignorance. These are facts easy to research. Microsoft has always had games that were PC only. The games you are listing as evidence that they are appealing to PC only crowds aren’t them lol

Why do you bring up this nonsense again. A Chinese guy (unrelated to the project) ran the YOUTUBE VIDEO on his laptop.

RTS games and flightsims are popular genres on pc, not on consoles. Why do you think we still don't even have a date when Gears Tactics is coming to Xbox? 

A $2000+ gaming laptop not being able to run that EA5 tech demo in 4k and 60fps is my whole point here. It being optimized for 30fps and 1440p is why people were a lot more impressed by it than seeing Xone games running on native 4k during MS's conference. 

true, but that wasn't the laptob running the actual demo, you picked up only half of the story

Why are you still arguing that the cross-gen period will be longer than the announced two years... oh yeah, because it fits your agenda.

We could also argue that Sony will return to PS4/PS5 cross-gen releases withing the next two years when/if the PS5 hardware base ain't big enough yet to sell enough blockbusters... their current strategy ain't written in stone either.

And your "If the average gaming pc still has a GTX1060, 4 years from now" argument is stupid. Are you expecting a complete standstill on the PC side while the new consoles prosper? The progress of PC hardware is as fast as the progress of console hardware... the only difference is that the shift to better hardware is more gradually and not in 3-4 year steps.

I dont know about that. Just clicks that at the begining of a new gen, consoles will be unrivaled in price to performance and they will be competing with high end rigs. So for that begining period I actually expect a slowdown in pc. But after the pc takes over in who knows how long, 1 year or 2, the pc space will be matching the consoles in price per performance. Who knows they might even beat the consoles. During that period is when pc will see another rise and from then we have to wait until theres enough adaptation such could be another year on top of that.

Not that I have any data. Just what makes sense as consoles will be at their most attractive at the begining of a launch. Taking attention from everything else. 

We don’t have a release date yet because the plan was to release it later in 2020 on consoles and then COVID happened. Either way, it’s coming, so your point is, per usual, incorrect and ultimately irrelevant anyway.

You don’t have a point here. You’re trying to say a tech demo was made tailoring specifically to the strengths of the PS5 yet a laptop ran it better. The tech demo was a scaling resolution with a max of 1440p and a fluctuating frame rate sometimes stable at 30 because Epic loaded it up with tons of super detailed content in it. Super detailed content that would apparently require hundreds of gigs of data for a real game according to Epic themselves. It isn’t a demo designed specifically for PS5, it’s a tech demo for UE5 which will run on every platform around. 

Also what is this Xbox conference you speak of? They have had an Inside Xbox stream... conferences were all canceled. Are you confused again? 

Personally I would hope that a next gen tech demo beats cross gen content otherwise that would be a massive failure on the part of the company making the tech demo. After all that is the point of tech demos.

No proof either, people should stop bringing it up unless you are a fluent in Mandarin and know exactly what the guy said.. and said engineer show proof of exact same demo, in its entirety running on a laptop. Tim Sweeney denied it, that's all you need to know.
