Unreal Engine 4 Demo for PS4, Reduced Quality?

Tagged: ps4, unreal engine 4

Unreal Engine 4 was present at Sony's Playstation 4 press conference, but that is no surprise. Epic Games has been present at several keynotes for new console launches. Last generation, Unreal Engine 3 kicked off both Xbox 360 and PS3 with demos of Gears of War and Unreal Tournament 2007, respectively. The PS4 received a continuation of the Elemental Demo first released at the end of E3 last June.

All I could think about when I watched the was, “This looks pretty bad. What happened?”

If you would like to follow along at home, both demos are available on Youtube:

As you can see from the animated GIF above, particle count appears to have been struck the worst. The eyes contain none of the particle effects in the PS4 version. There appears to be an order of magnitude or two more particles on the PC version than the PS4. There are no particle effects around the eyes of the statue. Whole segments of particles are not even rendered.

In this screenshot, downsampled to 660x355, the loss of physical detail is even more apparent. The big cluster of particles near the leg are not present in the PS4 version and the regular cluster is nowhere near as densely packed.

And the lighting, oh the lighting.

On the PS4 everything looks a lot higher contrast without a lot of the subtle lighting information. This loss of detail is most apparent with the volcano smoke and the glow of the hammer but are also obvious in the character model when viewed in the video.

Despite the 8GB of RAM, some of the textures also seem down-resolution. Everything appears to have much more of a plastic look to it.

Still, while computers still look better, at least high-end PC gaming will still be within the realm of scalability for quite some time. We have been hampered by being so far ahead of consoles that it was just not feasible to make full use of the extra power. At least that is looking to change.

Sony's Fourth Playstation (PS4) Specs Revealed

Subject: General Tech, Systems | February 20, 2013 - 03:53 PM |
Tagged: sony, ps4

We're currently in the middle of Sony's Playstation announcement and right off the bat they discussed system specifications.

(Update 2: Press conference was over a few hours ago, and we now have an official press release.)

PS4-01.png

The Playstation 4, as it will be titled, is very similar to a mid-range gaming PC. When discussing with developers, they requested for Sony to stick with a typical x86-based architecture. Of course that does not stop Sony from describing it as a “Supercharged PC architecture”. Still, they do seem to have quite a decent amount of hardware in this box.

  • 8-core x86 CPU
  • 2 Teraflops GPU integrated on same die (update: chip).
  • I did not hear AMD mentioned, but it totally is.
  • 8GB GDDR5 RAM (shared)
  • Stereo Camera on the controller with a light bar, like the Wii, to judge distance to TV.
  • Also touch sensor in the controller.
  • (Update/correction: At least a ...) Spindle-based Hard Drive

While these specifications have been sufficiently leaked in the recent past, we have not been able to pin down exactly how much RAM is provided. We found the development kit contained 8GB of system memory. The problem is that development kits require more RAM than the system it pretends to be to account for development tools and unoptimized assets.

As it turns out, the system itself will contain 8GB of GDDR5 shared between the CPU and GPU, which is quite a lot. Developers will need to finally push the PC platform past the 4GB RAM+VRAM 32-bit barrier in order to keep up with the next generation consoles.

Most of our gaming limitations were due to art assets being limited by memory constraints. Thanks to the new Sony console, PC releases could finally be taken off the 512MB-long leash of Sony and Microsoft.

(Update 2, cont.: The press release has official tech specs as below but are "subject to change")

 

Main Processor
Single-Chip Custom Processor
CPU: x86-64 AMD "Jaguar", 8 cores
GPU: 1.84 Teraflops, AMD next-generation Radeon(tm)-based graphics engine
Memory GDDR5 8GB
Hard Disk Drive Built-in
Optical Drive (Read-Only)
BD 6x CAV
DVD 8x CAV
I/O Ports Super-Speed USB (USB3.0), AUX
Communication
Ethernet (10BASE-T, 100BASE-TX, 1000BASE-T)
IEE 802.11 b/g/n
Bluetooth 2.1 (EDR)
AV output
HDMI
Analog-AV out
Digital Out

So clearly Sony was slightly rounding up when they claimed it was a 2 Teraflop GPU. Still, this looks to be a healthy computer.

We now have the official confirmation we needed that AMD Jaguar cores will power the PS4. Given AMD's big wins in the console platforms, I would wonder if game developers would be able to take some of the tricks they will learn in a few years and be able to start optimizing PC gamers for AMD CPUs.

GPUs too for that matter... this could mean a lot for AMD's PC gamers.

PlayStation 4 (PS4) Orbis Hardware Specifications - AMD APU or Discrete?

Subject: Graphics Cards, Processors | January 23, 2013 - 11:42 AM |
Tagged: southern islands, sony, ps4, playstation 4, orbis, Kaveri, bulldozer, APU, amd

Earlier today a report from Kotaku.com posted some details about the upcoming PlayStation console, code named Orbis and sometimes just called the PS4.  Kotaku author Luke Plunkett got the information from a 90 page PDF that details the development kit so the information is likely pretty accurate if incomplete.  It discusses a new controller and a completely new accounts system but I was mostly interested in the hardware details given.

We'll begin with the specs. And before we go any further, know that these are current specs for a PS4 development kit, not the final retail console itself. So while the general gist of the things you see here may be similar to what makes it into the actual commercial hardware, there's every chance some—if not all of it—changes, if only slightly.

This is key to keep in mind because here are the specs listed on the report:

  • 8GB of system memory
  • 2.2GB of graphics memory
  • 4 module (8 core) AMD Bulldozer CPU
  • AMD "R10xx" based GPU
  • 4x USB 3.0 ports and 2x Ethernet connections
  • Blu-ray drive
  • 160GB HDD
  • HDMI and optical audio output

We are essentially talking about an AMD FX-series processor with a Southern Islands based discrete card and I am nearly 100% sure that this will not match the configuration of the shipping system.  Think about it - would a console developer really want to have a processor that can draw more than 100 watts inside its box in addition to a discrete GPU?  I doubt it. 

kaveri2.jpg

Instead, let's go with the idea that this developer kit is simply meant to emulate some final specifications.  More than likely we are looking at an APU solution that combines Bulldozer or Steamroller cores along with GCN-based GPU SIMD arrays.  The most likely candidate is Kaveri, a 28nm based product that meets both of those requirements.  Josh recently discussed the future with Kaveri in a post during CES, worth checking out.  AMD has told us several times that Kaveri should be able to hit the 1.0 TFLOPs level of performance and if we compare to the current discrete GPUs would enable graphics performance similar to that of an under-clocked Radeon HD 7770.

There is some room for doubt though - Kaveri isn't supposed to be out until "late Q4" though its possible that the PS4 will be the first customer.  It is also possible that AMD is making a specific discrete GPU for implementation on the PS4 based on the GCN architecture that would be faster than the graphics performance expected on the Kaveri APU. 

kaveri.JPG

When speaking with our own Josh Walrath on this rumor, he tended to think that Sony and AMD would not use an APU but would rather combine a separate CPU and GPU on a single substrate, allowing for better yields than a combined APU part.  In order to make up for the slower memory controller interface (on substrate is not as fast as on-die) AMD might again utilize backside cache, just like the one used on the Xbox 360 today.  With process technology improvements its not unthinkable to see that jump to 30 or 40MB of cache.

With the debate of a 2013 or 2014 release still up in the air, there is plenty of time for this to change still but we will likely know for sure after our next trip to Taipei.

John Carmack Believes Next-Gen Consoles Will Continue Targeting 30FPS Games

Subject: General Tech | December 21, 2012 - 09:06 AM |
Tagged: xbox, ps4, gaming, games, consoles, carmack

While Nintendo has continued to pump out new gaming consoles, both Microsoft and Sony have been sitting on the current Xbox and PlayStation hardware for years. For example, the Xbox 360 is seven years old, and yet the Redmond company does not appear to be in any hurry to advance to better hardware with a new console. Sony is in a similar mindset with its PlayStation road map.

There have been rumors for the past couple years on the next Xbox and PlayStation, but there is one thing that is certain. Once gamers do (eventually) get a new console though, it will have substantially better hardware than the current generation. And considering that the latest games on the Xbox 360 and PlayStation 3 have started to push the hardware to its limit, developers are clamoring for better hardware as their engines outgrow the consoles. Visuals are still increasing on iterative console games but the frame rates are starting to slip as a result. PC gamers have Eyefinity, multi-GPU, AA, AF, higher resolutions, and unrestricted frame rates. Meanwhile, developers that want games on both console and PC platforms have to contend with the fact that the Xbox 360 and PS3 are limited to a frame rate target of around 30 FPS. (And the latest games are jast barely able to achieve that target.)

Unfortunately, while many console gamers likely expect the next generation of consoles to set the frames per second bar higher, a statement by John Carmack suggests otherwise. On Twitter the id Software founder stated that “unfortunately, I can pretty much guarantee that a lot of next gen games will still target 30 fps.”

Carmack_30FPS.jpg

It is an interesting statement from the mind of a game developer. When next generation consoles do come out, they will likely push more than 30FPS on average as games built on (tweaked) existing engines will run faster on the updated hardware. However, it seems that developers are more concerned with pushing visual quality instead of framerates. As developers start pushing the new hardware, the framerates will fall towards the 30 FPS target, much like the current generation of consoles are experiencing. I suppose gamers that want unrestricted fram rates will have to stick to PC gaming for the forseeable future.

Carmack is much more optimistic about higher framerates on PC games.

Do you think gamers care about higher framerates on their consoles?

Sony Buys Out Gaikai for $380 Million, A Stormy Future for Cloud Gaming?

Subject: General Tech | July 2, 2012 - 11:03 AM |
Tagged: sony, ps4, Internet, gaming, gaikai, cloud gaming

Gaikai, the streaming cloud gaming service was bought today by Sony Computer Entertainment. At this year’s Fusion Developer Summit, Gaikai stated its goal to be the gaming service on all of your devices, from your cell phone to Smart TV. Interestingly, the recent buyout from Sony raises questions about the future openness of the platform.

Purchased for $380 million, Sony plans to combine its game catalog with Gaikai’s streaming technology to provide cloud entertainment services. Gaikai CEO David Perry was quoted by The Verge as saying:

“We're honored to be able to help SCE rapidly harness the power of the interactive cloud and to continue to grow their ecosystem, to empower developers with new capabilities, to dramatically improve the reach of exciting content and to bring breathtaking new experiences to users worldwide.”

The biggest question I have about the future of Gaikai is whether not not it will now be a Sony-only technology. At AFDS, Gaikai showed off the technology running on Samsung Smart TVs, though it remains to be seen whether Sony will continue to license the technology to other companies. Should it remain Sony-only, the company could use that exclusivity as a feature-add for its consoles, Google TVs, blu ray players, and televisions. They could further use Gaikai to power its future consoles or to bring its entire library of console games to the PlayStation 3 and PlayStation Vita gaming platforms. The Verge speculates that Sony could be using the technology to bring its back-catalog of PS1 and PS2 games to the current generation console, now that it is otherwise no longer backwards compatible with the older hardware. That sounds like a very plausible plan of action for Sony.

Will Sony bring Gaikai-powered cloud gaming to the PS3?

You can find more additional quotes and speculation over at The Verge. What do you think will happen to Gaikai’s technology? Will Sony put it to good use or did they only buy it now to keep others from using it?

E3 sprouts rumours and facts about the next generation of consoles

[H]ard|OCP heard quite a bit about the new generation of consoles via the grape vine at E3.  The big winner is AMD, who will be providing the graphical power for all three of the next generation of major consoles as well as being in the running for putting a Bulldozer APU inside Sony's next game system.  IBM is the other competitor for providing Nintendo's core with an updated Cell processor, which also will be running in the next generation XBox.  Nintendo is also going with IBM, though they are looking at a custom built 45nm CPU.  This is very good news for AMD, with a guaranteed presence in every console and a possible hardware monopoly with Sony.

"Guys talk, you hear things. And at this year's E3 HardOCP picked up a lot of information about the upcoming hardware in the next generation consoles. It will be interesting to see if our rumor mill churns up truth or fiction. We wanted to get this out the week after E3, but we had some I's to dot and some T's to cross."
