It's just a bug...

Also on XB1



And BF1 is not the most CPU intensive game on console.

BF1 doesn't need a strong CPU to run well on PC unlike Just Cause 3 for instance.

 

I'd be cautious to compare PC to console, we have very little knowledge of what is causing high CPU usage on PC and it could be entirely optimized differently on PC than it would be on console. Given how weak console CPUs are relative to their GPU, there is a strong case to leverage GPGPU as much as possible there. Where for PC, where there's much more CPU available one would consider the possibility of the developers leveraging that and freeing up the GPU to push more graphics for instance.

Anyway, point taken though. I'm still waiting on a source from VGA, without it were making too many assumptions on the resolution. And if you have CPU data on the games I'd like to look at that as well. Not sure if it will answer the burning question but it may point us there.

 

PS4 (http://imgur.com/a/yx68P) and Xbox One (http://imgur.com/a/OSgIb). Both screenshots here are in the region of 1100x620. There really must be something wrong with the dynamic resolution on PS4 though, as it can drop much lower than any other game on the system.

 

How do you know it's not a CPU limitation instead of saying it must be a bug?

 

How much they can gain in a CPU limited scenario by dropping resolution? Especially in a console environment where it has lower overhead vs PC?

 

I believe it was a figure of speech, although acknowledging that might be less exciting than warrioring.

 

What's so CPU intensive in this video ?



Let's be serious... we're talking about a 160x90 resolution...

 

It's a possible explanation on why PS4 doesn't perform as well as Xbox One, since the XB has more CPU. That's about the only resource XB has more of than the PS.

Oh. I'm not talking about that ultra low low res. That's certainly a bug. I'm talking about why XB seems to perform better than PS during normal situations.

 

Ok, i never said it was a bug in normal situations.

 

Regarding BF1; is it worth considering the performance of the PS4 and XBOX1 with Star Wars:Battlefront, considering that was based on Frostbite engine as well.
In that game the PS4 handled higher resolutions to the XBOX1, separately along with that the PS4 had noteable batch time performance gains with regards to culling/rendering and their engine; think it was back in the GDC presentation about Frostbite and optimization.
However I appreciate BF1 has evolved this a bit more.

a Sony's employee has commented that DF director can't discern the difference between 4k and checkerboard rendering, which is good news.

-can't tell the difference between checkerboard 4K and native 4K unless you're practically kissing your tv, it's that good

-had PS4 Pro on for ~8 hours straight with Infinite Warfare running, no heating problems and it was super quiet the entire time.
couldn't even hear the fan until putting phone (what he was recording with) behind the system --1h54m35s mark into the video

YouTube video should start where he talks about that:

 

DF have missed whopping great technical issues/features in the past.

 

That's not how the DF review describes it.

 

I've seen everything from quietest PS4 to closer to original PS4. DF was the only site that I've seen say that it's closer to the original; most say that it's quiet.

 

They didn't say OG. they said C-chassis (model 1200) which is a 'quiet' model of PS4. ~10db lower than the OG in some cases. They said the problem is not the noise but rather the pitch.

Don't know why people mistook that for OG model. Maybe it's the phrasing.

 

Well I wouldn't have the faintest idea what a C-chassis ps4 is, so yeah maybe they could have explained it better.

 

How do you three c-shells

 

You want better explanation ? DF just did The Last of Us Pro version:


In the description: "Is it really native 4K in the 30fps mode ?"
At 3:34 it's directly written on the video: "Native 3200x1800 (30fps)"
But they discuss resolutions in the video and say there are 2 modes: native 4K at 30fps and 1800p at 60fps.

 

does it make a difference in IQ on a 1080p TV to play either 4K 30fps or 1800p 60fps modes ?
