*updated* complete trancript-Microsoft to unlock reserved GPU performance for Xbox One development

PS4 doesn't need GPU reservation for its OS whereas X1 need it for Application snaps

That's false.

Xbox 360, PS3, Wiiu, X1, and PS4 all need some GPU reserved, because regardless of 'snapped' apps, hitting the 'home' button brings up an overlay, and that overlay takes memory, GPU cycles, CPU cycles, etc.

Yes, all modern console need to reserve a bit of the GPU for system UI... Microsoft is just the only one that's utterly transparent about it... Sony likes to hide important, critical details like that...

I was talking about the resources held back in general not just one area, I don't think it's accurate to say that Sony won't free up more resources (not just RAM) as time goes on just because they haven't made some big announcement about it yet. We'll see how it goes, I'm not saying they will or won't and I know you only said "apparently" but just because MS announced today that they are going to free up some GPU resources "in the future" that doesn't mean they are the only ones that will be doing that.

If you mean GPU cycles, it almost certainly won't happen on PS4. Sony has no incentive to do so. Their incentives are in the opposite direction in fact. You are welcome to disagree though.

Misterxmedia's insider called and said to keep digging, and we have all the pieces.

Kidding.

But....


"Evolving "mono driver""? "Last munite hardware tweaks"? This DOES sound like insider speak, IMO. He said devs were just now getting access to a stereo driver. Why did they put it in quotes, or even say it at all?

Yeah it's odd, as crazy as all the MisterX stuff is, the Insider has been right about several random, significant things over the last year or so.
And last week he said Eurogamer would soon have the scoop on the GPU, and now they announce a big tech article coming this weekend. Hmm. Gotta give him a little credit.

Microsoft: “System processing” takes up 10 percent of Xbox One GPU time

Wired
The Xbox One's ability to run up to four apps in the background (or on the side via Snap mode) during gameplay and to switch from a game to those apps almost instantaneously obviously comes at some cost to the system's maximum theoretical gaming performance. Now, thanks to an interview with Xbox technical fellow Andrew Goossen over at Digital Foundry we have some idea of the scale of that performance cost.

"Xbox One has a conservative 10 percent time-sliced reservation on the GPU for system processing," Goossen told the site. "This is used both for the GPGPU processing for Kinect and for the rendering of concurrent system content such as snap mode."

It's important to note that additional processing time for the next-generation Kinect sensor is included in that 10 percent number. Still, setting aside nearly a tenth of the GPU's processing time to support background execution of non-gaming apps is a bit surprising.

During a recent demonstration of the Xbox One interface, Microsoft Director of Product Planning Albert Penello showed me how running multiple apps on the side or behind a concurrent game didn't lead to any noticeable degradation in gaming performance. Indeed, setting aside a good chunk of GPU processing to explicitly handle nongaming apps ensures that gaming performance doesn't bounce up and down depending on what may or may not be running in the background.

The downside, of course, is that developers are unable to use that reserved chunk of processing power. Not to worry, though; Goossen says that Microsoft plans to open up this power to developers in the future in a way that doesn't impact the system's background functions.

"The GPU hardware scheduler is designed to maximize throughput and automatically fills 'holes' in the high-priority processing," Goossen said. "This can allow the system rendering to make use of the ROPs for fill, for example, while the title is simultaneously doing synchronous compute operations on the compute units."

Sony's PlayStation 4 also allows for non-gaming apps to run in the background while games are playing and for instant switching between these apps, but the company has not gone into detail about what kind of impact this functionality has on the system's processing load.

All OS' have overhead that take cpu/gpu cycles that will never allow 100% utilization elsewhere, don't have to be a tech expert to know that. What I find amusing is how severely the hypervisor is being underestimated. I have a feeling that Microsoft intends to make full use of hyper-v to free up that extra gpu and extra ram. Dynamic scaling will allow apps to be snapped, allow background tasks, and popping up the gpu accelerated UI without delay/lag all while allowing devs better gpu utilization

I love how this is suddenly news. MS "revealed" it an hour after the announcement.

And the 10% number appears to just be Microsoft being conservative, and not at all indicative of the actual time slice that was needed to run the host operating system.

It looks like it has message pop-ups and it does upload video, and download games in the background. However rather than running the game simultaneously with the executive, the game needs to be suspended to get back to the full dashboard.

I suspect/assume the ram reservation is for Sony to add full multi-tasking later on in the PS4 life cycle.

Yeah I think what I saw where the guy was doing a more full blown messaging scenario he was just watching a stream of someone playing Killzone.. before he jumped in to play he was invited by his hot female friend to watch Killzone, because that's what most hot California girls are doing on a random afternoon.. watching people play Killzone online and inviting their male model friends to watch too.

But yeah, anything that does an overlay like that during a game is going to take some GPU power for the visual effects. Full app snapping obviously takes quite a bit more though.

I can't imagine PS4 has as much reserved unless Sony has reserved it for future use.
 
just more proof of XB1 upcoming dominance and most likely the end of the playstation brand. Will be good to see uncharted and Sony first party games like The Show and Gran Turismo on the XB2.
 
I thought he was serious. I wasn't aware that his posts were jokes.

No...you will hear excuses such as....

"The devs were PAID by Microsoft to make the game look the same on both consoles"

"The Xbox 1 is holding the PS4 back"

oh...and my personal favorite gem....

"Lazy devs!"

When a multiplatform game comes out and LOOKS better on the Xbox1 then all hell will break loose.

Holy s***, imagine that yeah. It's very doubtful and i think games like Watch Dogs,AC4,NFS Rivals and BF4 will all end up like Multiplats these days...like GTA V for example, fantastic on both systems and where you need to analyze like crazy to spot real differences.
 
This is good news to allow deveoplers access to an extra 10% of the GPU.

Will this also give the ESRAM some more fire power, from my understanding it is a evolution step up from the eDRAM and that worked wonders for the 360.... Astrograd I would enjoy your input on this. Thanks..

It's GPU cycles in the form of time slices. Nothing to do with eSRAM. Sorry. ;)
