So is Cell being used in basically every Toshiba TV moving forward?

Yamauchi said they're at the very limits of the PS3, but he thinks there is still headroom for improvement.
An interview with Housemarque regarding the stereoscopic version of Super Stardust HD:
"That was of course just the beginning: after that we had to optimise a lot, as we now had 8.3ms instead of 16.7ms to render a frame. Luckily we had 50 per cent of the SPU power left, so we tapped into that. The current version of the game heavily pre-processes the data that goes to RSX to make sure it can chew through it as quickly as possible."
"For SSHD it was mainly drawcalls and polygons - we have lots of objects with lots of polygons and massive particle effects. I solved the issue by moving vertex processing from GPU to SPU and merging as many objects as possible to one drawcall. Previously every asteroid chunk and every enemy was in a separate drawcall; in the stereo version they go out in a few fell swoops."

Doesnt that mean its rendering two images, each rendering at 60fps, to produce the 3D stereoscope?°°ToMmY°° said:
yes. It will render a 720p image for each eye at 60 fps. I was reading the articles, and IIRC he (guy from Housemarque) said that they had 50% of the SPU left to increase the frame rate to 120. Are they only able to do this because Stardust isn't a full on game like Uncharted, batman etc etc? If couldn't tell I'm just a wanna be tech guy

It has been since the beginning and Sony showed several tech demos drawing a lot of polygons on the SPUs alone. That's why when people say "PS3 is basically only capable of what a GT7800 is capable of" they are wrong. It's more complicated than that.

I'll take 30fps on each eye over 60fps in non-3D any day. The effect is just that impressive.
But also, I am not sure why you are disappointed. That's how "3D" works. When you work on a 3D movie you have to render two frames for every frame (one for each eye). That's what doing all the visual FX on Avatar was like. There's nothing a firmware update could do to get rid of that.

It never was actual 1080p, but 1280x1080 at most. 720p120 now sounds like they reached a milestone.

Check here: http://en.wikipedia.org/wiki/HDMI#Version_1.4
HDMI 1.3 has the same bandwidth as HDMI 1.4. The latter adds tags to mark 3D content.

Thank you :lol
"The consoles price-to-performance ratio inspired one Air Force research team to place an order for 1,700 of them to go with the 336 they already have.
The brains behind the Air Force Research Laboratory in Rome, N.Y., are clustering the consoles, along with some off-the-shelf graphic processing units, to create a supercomputer nearly 100,000 times faster than high-end computer processors sold today."

More details with regard to anti-aliasing on the Cell's SPUs, now regarding God of War 3:
http://www.realtimerendering.com/blog/more-on-god-of-war-iii-antialiasing/
A snip: "Contrarily to what I have read on few forums, we are not firing the SPUs at the end of the frame and then wait for the results the next frame. We couldnt afford to add any significant latency. For this kind of game, gameplay is first, then quality, then framerate. We had the same issue with vsync, we had to come up with ways to use the existing latency. So instead of waiting for the results next frame, we are using the SPUs as parallel coprocessors of the RSX and we use the time we would have spent on the RSX to start the next frame. With 3 ms or 4 ms of SPU latency at most, we are faster than the original 6ms of RSX time we saved."

It's really interesting reading about this! I was really amazed with GoW3's outstanding graphics in the gameplay, so it's a treat to read on the process of optimizing the game to reach that point.SamBa said:
Crysis 2 PS3 'performs better than 360 version'
http://www.computerandvideogames.com/article.php?id=242728?cid=OTC-RSS&attr=CVG-General-RSS
Doubt they did much optimizing for Blu-Ray capacity/streaming though. And likely they will be able to do much more on the platform with future low level OS / game engine optimizations for the eight 3.2 Ghz processors inside the PS3.
Nice to read coming from a highly acclaimed PC developer using a multi-platform engine.

Of course it's possible to make further improvements.
But to optimize for Blu-Ray/capacity streaming I don't think the PS3 version will ship with higher quality / more varierty assets than the PC version, or they will have to make it a multi-DVD game.
Also I think they won't develop the game around the capabilties of the Cell processor per se. You can't have one version of the game with for instance much more onscreen activity than the 360 is capable of, such things would alter the core game a lot between different versions.

Now that's just nonsense... Don't forget that everything on the PC 9GB DVD will be heavily compressed. It won't on a bluray.SamBa said:
Metalmurphy said:
But most on Blu-Ray is at least as well compressed as well. It just makes more sense as the Cell can decompress the data faster than the Blu-Ray drive could read and is great for that.
XBox 360 DVDs can only hold 6.8 GB of game data, likely it's optimised for that.

SamBa said:
No, it really isn't. Compressed textures aren't the same as compressing everything in cab files for installation.
And why are you talking about Xbox 360 now when we we're talking about the PC version?
Metalmurphy said:
Because it's the platform with the lowest capacity for storage. This is a multi-platform game also on the XBox 360.
A downgraded Cell can for instance decode 48 MPEG-2 streams simultaneously as demonstrated by Toshiba.
Of course regarding lossy formats it may make more sense to choose lossless formats on the PS3 vs PC.
In the beginning many were sceptical, after games like Uncharted 2 and God of War 3 have people here become more open minded with regard to the Cell?

SamBa said:
none of the consoles have problem with playback of compressed videos, so it does not matter that PS3 can decompress them fast, you can not gain better compression like that.
so all of them are compressed, some just have higher bandwidth/resolution/quality for the codec.
An older quote with regard to Heavy Rain:
"I think this game can only be done on Playstation 3, We used all the SPUs.
I think to do the visuals, and all the stuff were doing would be too difficult [on the 360]. There are amazing physics there, and stuff with crowds that you just couldnt really get."
Of course they also stated:
You need to keep in mind that Heavy Rain is our first title on PS3,
Its not the second or third generation of games on the same platform. Weve just discovered the platform right now. So yeah, theres plenty of room for improvement Im sure.
At Quantic Dream we know we can do much better than what we do here.
