PlayStation 4 and Xbox One resolution discussion.

LOL. I really need to go to bed. Zzzzzz... Later gamers.

Same...I keep getting dragged in..wth

Seems like the black crush was caused by digital foundry and isn't an issue with XBO. No crushed blacks and retains vibrancy; lovin the colors. Gray shooters are dead!

DF kept contrast at default. X1 at a system level clearly has lower contrast...same with 360 vs. ps3.

Some are acting on youtube as if you can't change contrast/brightness in game on just about all games since last 2 gens lol.

Right, and there are ~many~ scaling systems that require branching and can simply not be done on a GPU.

You are getting hung up on the idea that there are a couple of scaling techniques. There are not, there are hundreds. In particular there is a while area of research around scaling with an intact Z buffer. It can be used to enhance edges and reduce jag. It however requires branching to execute, thus can not be done on a GPU. You would need some sort of memory coherency system between the CPU and GPU to make that happen.

Oh wait, never mind.

Also, if Sony is sending the full image over wifi without re-sizing it before compressing it, they have successfully executed the most naive remote desktop solution in the history of remote desktop...

No different than Netflix sending you a 1080p video over Wifi, since you know...only thing PS4 is doing is sending a video to Vita, the game is still being rendered on the PS4. Video compression...how does it work? (Which is exactly one of the things that secondary chip does). And remote desktop will totally send you a full resolution feed if you set it to do such...>.>

And I'm well aware on the different scaling algorithms, which has very little to do with the argument you put forth. And you're right they would need branching...that those DMA engines you speak about do not have nor are they as you've stated programmable, because they're fixed function hardware; they're included to do set things that has been clearly outlined. All scaling is handled by XBO's display planes.

Thats because the PS4 doesn't have a scaler... The hardware scaler on the PS4 is reserved for mandatory Vita second screen stuff(it is fixed function anyhow).

No, it does have a scaler, which is why it's output is 1080p. It has 2 scanout engines (i.e. scalers). 1 is for games and the other is for the OS overlays and Vita.

Wii was popular because it appealed to people who wouldn't normally play video games. Not because core gamers enjoyed it. I'm a firm believer that core gamers actually enjoy nice graphics. Do you consider yourself a core gamer? would you be happy with only a Wii? I doubt it.

Of coarse the wii was popular cause of things like that, but do not be so naive as to think many a core gamer did not fully enjoy many games it had to offer. Gamers enjoying nice graphics ( which we all do) is a far cry for it being the sole reason many look forward to a new generation. That is what your previous post implies. Your 2 comments on the matter are far removed from one another IMO.

guess we are going to have to agree to disagree because I fully believe that the main reason each generation is so appealing is because of the graphical upgrades. Nothing else really changes much. Most games still have pretty stupid AI. To this day Halo still has the best enemy AI I've seen which is pretty sad.

I will just assume you have forgotten how games were to what they are, and are not playing Ignorant to further stress your point. Many things change. While graphics are often at the forefront of discussion, and granted, is an aspect many look forward to. There are many more things people seek beyond it, and ahead of it.

Go play forza 1 then play Forza 3/4. The difference is vast. A lot of it people would not be able to firmly recognize/pin point, but they would notice it. Look at BF:MC to BC2 or BF3. Look at Tomb Raider 1/2 to the new Origin Tomb raider. I could go on with every franchise from past gen that survived in to this one. The differences are vast and go well beyond mere visuals.

Could you point out these algorithms that cannot be done on the GPU for scaling. As it stands, the current gen GPU's and both next gen consoles only take a handful of cycles to branch if its not taken, so i am interested in what can't be done on them.

Too bad that's not true. PS4 has a hardware scaler by virtue of the fact it's included in GCN architecture by default. It'd take more money to remove it than to keep it. The real reason is MS seems to have gone above and beyond just simply having GCN scaler; and have included a few different filters to help combat the blurriness that is generally associated with image scaling. I doubt Sony did anything of the sort (I'd eat crow if I was wrong, but I'm probably not) And the swizzle has nothing to do with the scaler in this case. That should be obvious since on all modern GPUs, swizzling is done with shaders...that are programmable (why do you think the HPC sector uses GPU based scaling algorithms?...and have been for like ever).

PS4 doesn't scale the image to Vita. It sends the framebuffer as is and Vita scales the image itself...like it always has (much like PSP and PS3, also PS4 uses a secondary chip to handle communication to Vita).

But other than that, he's right on!

A few insiders on GAF are saying that the XBO version is an old build and they have it up to 1080p now AND HDAO has been added from what they heard.

I need a "ohsnap" gif.

I like it. I also believe it as much as any other GAFsourced rumor. My inside sources tell me that they're all downgraded from the WiiU version, which is actually rendered in 4k before being downscaled to dat 1080p.
