Xbox one x really 4k?

[Carsomyr]

Are games really in 4k on the xbox one x?
I hear it's certain games. But even then I hear all this talk about dynamic resolution

Can you give me some wisdom on the matter please?

Well, it uses checkerboard rendering. That results in 2K 'shading'. The imaginative ways in which consoles use this 2K-shaded basis into 4K-antialiased basis is what constitutes the eponymous 4K-rendering.
Like, for instance, aliased edges may suck at non-4K, or rendering in supersampled mode increases shader details. These are some of the ways in which the hardware renders better output - since shaders are 'unified' it does not matter to the hardware whether you use it to render more vertexes(geometry), or pixels(shading), or even filtering(HRAA-CLUT). Personally, I'm expecting a bilateral filter option along with a 2xAA mode in the near future. We are well-into Gaussian blurring era, it is only a matter of time until bilateral-recovery antialiasing becomes commonplace.

Some games are native 4K others are basically upscaled

What they both said...Games that aren't all that much are 4K and the ones that are are 2k with multisampling at 2x which technically is a 4k render if you twist the definition enough.

Yes, it does output a true 4K signal and graphics rendering, but the answer is a little more complicated than that.

It's possible to have a game render at a full 4K like on a PC. However, because the console is only about as powerful as a "midrange PC", which is a bit of a nebulous metric to say the least, it can't do so without the framerate tanking a lot of the time. Therefore, while the physical signal to the TV/monitor is 4K, the rendering engine will usually do something lower, like 1440p, 900p etc to maintain a decent framerate. Since frames take different amounts of time to draw, the rendering engine resolution will change dynamically with the scene to keep the framerate up.

The PS4 Pro does something similar, but has less horsepower, so usually renders at 2K with checkerboard rendering unless the game is really light on the graphics load. Might as well just do 1080p instead, I guess.

Really, there's no way out of having a high end PC to do 4K properly...

Hope that clarifies it!

Realistically the consoles lack the grunt to push true 4K unless you play Tetris.

Resolution =/= render quality. It's just a number of unique pixels on screen. How they are used = render quality. And the consoles, even the new ones, cannot truly render native 4K. There is always trickery involved, some obvious, most of it less obvious, but always visible if you know what to look for. And as time passes, you will. I still vividly remember the massive differences in IQ on my PS3 depending on the game. Some stuff was in native render res and some was scaled to death (Fallout 3, hi).

 

[Vya Domus]

Either they run at some sub-4K resolution and are up scaled by usual means or they use checkerboarding where the horizontal resolution is halved and a special upscaling method is used.

Few run at native 4K and even if all would run at 4K it still wouldn't have been very impressive since they are almost all capped at 30fps.

 

[Durvelle27]

As a Xbox one x owner most games are in 4k most ain't most games I've played on it runs 4k on HDR if your TV supports it. Your Xbox 360 games are not in 4k there 1080p. It also plays 4k movie disk and streams 4k movie's and tv shows. That depends on how fast your internet is. I've been really happy with my xbox one x. Most bad reviews are Sony fan boys I own all 3 platforms I like them all.

What

No most games are not 4K. And not even a lot support HDR.

And no the Xbox 360 is not 1080p. Half of the 360s library is 720/900p with few at actual 1080p.

 

[Durvelle27]

I own the thing I know what it does

And that means what exactly ?

I own the OG Xbox One, Xbox One S, Xbox One X, and PS4 Slim

Just because you own it means fidelity squat when developers themselves release the information on what the games run and at what FPS.

watch digital foudry videos on youtube, they have excellent analysis of console games. x1x usually runs 3200x1800 at 30 fps IIRC but it does 1920x1080 60 fps pretty well.

I tell you, I'd rather have 1080p at a smooth 60fps than a stuttery higher resolution any day. This includes a steady 30fps which shows judders all over the place and looks awful.

Yeah, but 4k is the new hotness buzzword, and most casual console gamers only want the new hotness. The console could be rendering the game at 720p at 15FPS, just upscaling to 4k, and your average console gamer would constantly brag about how great it looks on their 4K TV.

Yeah, cuz bigga numbahz iz betta! That's marketing for you.

 

[cucker tarlson]

I think consoles should target something in between 1080p and 4K at 50 fps.

Xbox One X also has the option of 1440p @144Hz and FreeSync over 4K

 

[mtcn77]

2K 'shading' is actually good, in the sense it compromises texture quality like -2x AF loss. Edge details are 4K. Texture wise, you are held back much earlier by the texture bandwidth(8n reads from memory per texture AF filtering level) than rendered pixels. Nvidia overcame this somewhat through compression, however they didn't make the distinction - people kept bickering about the texture quality.

I have also an Xbox One S besides my multi use desktop. I found it very convenient to set the S with 1080p resolution + HDR (where HDR automatically shows up on titles like Mass Effect Andromeda) but leaving the full 4K on video contents (including Blu Ray disks).

I think that those systems (X too, maybe?) are able to fully intend the 4K on video output only. The 3D rendering side, as someone said, it works in a tricky way due to the possible dynamic resolution scaling factor. I noticed also, that few games have dynamic v-sync on/off in order to save frame rates. It is pretty much visible from anyone is accustomed on solid PC hardware

By the way, I usually play on my LG 43UJ701V Silver, a mid level Smart TV with a lot of interesting features. Check it out here if interested.

I would say a vast majority of games are 1440p and then upscaled to 4k, but there are some native 4k games out there.

 

[king of swag187]

The vast majority of games are still 720P-1080P but at a faster framerate and the built in scaler locked to its limit for most of the time. Games specifically optimized for it are run at 1300p-1500P on average, most are still 1080P but with better visuals/higher FPS, which I prefer. Even the base Xbox One can theoritcatlly support higher FPS than 60, but Microsoft locks it at 60 for some odd reason. Its not like games could push over it anyways, with the garbage Jaguar CPU. If only the went with a 8 core Intel of the time....

Not quite true.
Xbox One X plays almost all enhanced older games at native 4K, and as for modern titles, here's a list I dug up form Digital Foundry articles. All the titles are native (locked) 4K:
Shadow of the TR
Forza Horizon 4 (and I believe most XBOne Forza games)
No Mans Sky
Far Cry 5
Crash Bandicoot
Metro Exodus
Destiny 2
Hitman

 

[king of swag187]

Of course it can run "enhanced" 360 games at 4K, the base consoles could as well if Microsoft allowed them too.
As for the aforementioned games, they run at a stuttery 4k30fps low-medium at best. It's just not a truly playable experience, and you're better off at 1080 60FPS

Resolution may be the same amount of pixels, but the render quality can be far lower, and the ingame graphics settings are definitely not 'high'.

I don’t get where you get stuttery from. Yes some games are 30 FPS and higher would be better but even at 30 FPS it is very smooth with no hiccups. I have no issues playing on the Xbox One X and my 4K TV. And your average console gamer wouldn’t even know the difference.

Possibly but it still produces a great quality image

30 FPS being 'smooth' and 4K being a high quality image. Let's just agree to disagree. You don't miss what you don't (or rather: can't) have, I guess.

Try playing this game and play around with render quality settings and you can see how easy it is 'to put 4K' on a box and not say a damn thing about actual quality

Render scaling has been introduced precisely to make 4K playable on low end hardware. When you put it on medium/low, it really is comparable to 2005 graphics, ie internal 720p rendering and texture quality.

Yes a stable locked 30 FPS with no dips can indeed be smooth

And yes 4K does produce a higher quality image even with lower details

And what do you mean don’t or can’t have

I have gamed on 4K on PC with my previous rig and 1440@120Hz. So yes I can tell the difference

Consoles are much better optimized than PC. So with 30 FPS on a console there’s no overhead unlike PC which in turn can introduce stutter which isn’t all ways caused by the 30 FPS. You have many variables that can cause stuttering frame times, Over VRAM limit, inconsistent clocks, background activity etc

Consoles don’t run into those issues.
