PS4 ICE Team Programmer: Surface Tiling/Detiling On The CPU Is 10-100x Faster Now
- Thread starter viveks86
- Start date
Sounds like a future firmware update

Doesn't the PS4 have 10.25 GB of RAM?
8GB GDDR5
2.25GB DDR3 (was discovered in a tear down at launch)
....who know what goes where?
I could be wrong about the amounts - please correct me if I am
The animation improving from Season 1 to the final season
This is pretty standard for consoles. The initial versions of the SDKs have a lot of "just get it running" code, then you go back and optimize after hardware is final.

They lost arguably the best person to head such a team to ICE (Corrine). They do have their D3D team of course, though. They also have a team responsible for the SDK on the XB1. So I'd say they have equivalent resources, just not in a unified team.
No, PS4 has 8GB GDDR5 for main system.
A background processor has a 256mb Ram chip available to it, I can't remember what sort of ram, I wanna guess DDR3.
Uh seriously? I knew it uses ddr3 for the os features but I don't know it has 2 gb of 'secret ram'. What about DF leaks? He said part of gddr5 it's used for the xmb, is it false?

This isn't that terribly significant in the scheme of things. Any similarly skilled developer would likely arrive at a similar or identical solution. And with any IP development, there's always the weighing of patent vs. trade secret. I think most opt for trade secret in cases similar to this. The exception I can think of is the patent Microsoft got for the new lighting algorithm Corrine Yu developed, but then that'd also be why Sony decided to nab her. Big talent.
ICE Team isn't really the equivalence of those things, because Sony also have a team to write the APU and SDK. It's a team set up specially to work on programming techniques for PlayStation hardware that helps all of their internal studios. Part of the reason for the huge gulf in visual quality (in addition to the beefier hardware) last gen was MS lacking an equivalent.

They do. They work on DirectX. However, since DirectX need to work on wide range of hardware, their talent is spread thin I assume.
Ah, now it's clear.

256 MB (2Gb) in the secondary chip. Also gddr3 which is interesting
Edit: Maxconsole is wrong here. It's DDR3
Motherfucking BOOM, yo. I love these cats. I knew it was the devs' problem ever since Infinity Ward launched that game that was outputting more frames per second than people's TVs could show because they don't know what they're doing and didn't have Sledgehammer to hold their hands.
...so what you're saying is, MS don't have something like ICE Team.

What sort of Gamecubes-taped-together increase are we talking here?

So PS4 has a PS3 hidden inside it?

It's all pops and buzzes to me, but something tells me I should be glad I bought a PS4.

MS also has an outreach team that assists developers too. I'm simply stating they're not all under one roof like ICE is. ICE also seems to cause a greater occurrence of 1st party studio parity in technology too. ICE does 3rd party visits too. Cort was at Bungie a couple of months ago.

I'm right ^_^

SCEI (Sony Computer Entertainment, Inc.) CXD90026G SoC (includes AMD "Jaguar" Cores and AMD Radeon Graphics GPU)
Samsung K4G41325FC-HC03 4 Gb (512 MB) GDDR5 RAM (total of 16 x 512 MB = 8 GB)
SCEI CXD90025G Secondary/Low Power Processor for Network Tasks
Samsung K4B2G1646E-BCK0 2Gb DDR3 SDRAM
Macronix MX25L25635FMI 256Mb Serial Flash Memory
Marvell 88EC060-NN82 Ethernet Controller
SCEI 1327KM44S
---------------------------
So....
8 GB GDDR5 RAM
+
2GB DDR3 RAM
+
256MB flash RAM/memory
=
10.25GB total RAM
Edit: I'm wrong, it's like 8.25 RAM
256 MB (2 GB) uh? What do you mean?
Again...none of these are the same thing as ICE Team.
MS creative culture seems to be separate silos that don't interact. They're outright hostile to each other. It seems to have bled into their games studios too with less than stellar results.

Ask me about the GAF Notebook
Yeah fuck if you are getting those gains just how bad was the original implementation?
Still good news for the PS4 games going forward.

GB isn't the same as Gb

Sorry no, the 256MB of flash Memory is more of an OS/Firmware thing.
Also it's 2Gb not 2GB, Gb = Gigabit. 1 byte = 8 bits, 2Gb = 256MB

You think D3D team don't provide support for devs?

How can anyone come to the conclusion that the PS4 has any AF issues based on a single multiplatform game?
Boggles my mind.
I don't know, but ICE Team work only on Sony's PlayStation hardware, and as you said, the D3D team are building a high-level API, not low-level, hardware-specific tools.

Curious to hear this as well. It's good that's it's faster now, but 10-100x faster compared to what?
Strider, outlast and Thief, I count three. That said, it's strange that the PS4 version if lacking it. But I wouldn't yet call it an issue that is caused by the PS4 hardware.
wow, "struggling" because one poorly optimized cross-gen game didn't have it.

At this point it's just a semantics argument of existence of resources vs organization. I've acknowledged they're not co-located. Don't know what else I can say.
That may be changing a bit soon http://www.tomshardware.com/news/directx-direct3d-opengl-mantle,26167.html
Could also just be reactionary vaporware to prevent devs from abandoning their API too.
It's not a single multiplatform game. It's Strider, Thief & Outlast.
Nah dawg, Pennello said they got the technical fellowes. They know what they're doing. They're multidisciplinarian, and MS even provides some of them to do interviews with Eurogamer about the technical virtues of balance. Oh, and you don't need ice when you've got clouds, or something.
If anything, I'm glad to see that the devs there keep on working on optimizations, even small ones (I suspect that Microsoft has a similar team doing the same types of things for Xbox One, which is also good). The reference implementation for surface tiling and detiling was probably good enough for most purposes, but the team was willing to spend some time improving it anyway, when they would have been fully justified leaving it 'good enough' as it was. Anything that allows game devs to eke another fraction of a percent of performance out of the hardware is potentially beneficial.
