Todd Howard on Blu-ray and data duplication |
Listed in: PS3 Tags: Bethesda, EGM, playstation 3 updates
Ó
GameSetWatch reports that hidden away in an EGM story about Blu-ray vs. HD-DVD, a quote by Todd Howard on the PS3 version of The Elder Scrolls IV: Oblivion raises eyebrows. Howard said: "Drive speed matters more to me [than capacity], and Blu-ray is slower." Furthermore, EGM noted that "...the PS3 Oblivion team compensated for the slower drive by duplicating data across the Blu-ray disc, making it faster to find and load."
Replicating data in order to compensate for slow "seek time" does seem to negate the advantage of having higher capacity. Ouchies. Anyway, people have noted that replication of data to lower seek times have been done before, particularly in the PSP and with the UMD format. However they still add that it does negate, somewhat, the storage advantage.
Oblivion for the PS3 has been pushed to March 2007. It was supposed to be released around early November or so, just in time for the PS3 launch date. From the looks of things, Bethesda will still have their product released near launch... European launch.

"Is Blu-ray really a good medium for games?"

How is that negative? Sure it's an effort - but the added capacity has the option of doing it .. so what's the difference?
One can have all the replicated data and still have more content than on a DVD.. so better Seek times/loading with more content... through replication..? ... Positive imo.
I rather blu-ray...

Use the HDD Idiot...
The Entire Size of Oblivion is 4600Mb...Pre-Install 600mb of Compressed Data Containing The most Frequently Used Data...and Increase the Real-Time Streaming Speed..
The Hdd Can Transfare Data at 34.5Mb/Sec the Blu/ray at 9Mb/sec..
Is it So Hard...Todd.....you are too Soft to Force Players to Install 600Mb or 700Mb.
Bah....Its Multi-Platform,so i Expect No Less.

It Says the 360 12x DVD reads at 16Mb/sec.....False...thats the Maximum Reading Speed.
The DVD reading is Not Constant...Making it Troublsome for Games Designed to Stream like GTA...it Goes Down to 8Mb/Sec and Upto 16Mb/sec in the Outward Layers of the DVD..so the Average is Actually a Non-Constant 12Mb/sec
In the Past Generation....Developers used to Add Dump Files..to Push The Data in the OuterLayer of the DVD and Increase Loading Speed..However this Cannot Be Done this Generation.
Games Like Lair Already Have Maps of Over 4Gb for a single Map.....Blue Dragon Was Made into 3 Discs...Future Games will Be Even Bigger,they Cant Use the Dump Files Method to Push data and Increase Load-speeds in DVD format,the Entire DVD9 is Barely Enough to fit a game..
Example...Blue dragon which Shipped in 3 Discs..
So the reading Speed of the 360 is a Non-Constant 12Mb/sec unlike the Biased Link you Gave which Sayz its 16Mb/sec
The PS3 alwayz has the Advantage of the HDD as standard...with a transfare rate of 34Mb/sec...Which is Extremely High,A talented Developer Like Square-Enix and Factor 5[Lair] can Acheive Incredible Streaming By Clever Usage of the Hdd and Blu-ray Combined..
Thats All....if Todd doesnt use the Hdd to Stream...He,s Just a Moron....Lair is Using it,Why Doesnt He. ;)

BUT.. they don't go into the fact that some games will need to be "installed" into the hard drive to reduce load time, or some games will have to do what Oblivion does (data dupes). Kinda.. emm.. like a illusion to make Blu-Ray seem like a good product. Now what happens if you don't have that HDD.. more tricks.. ::nods::
(BTW this is concerning data (games) not movies)

It still averages out to DVD still being faster in the end. Arstechnica is biased in no way, and is a very technical site...i've read that article or one similar from them and it mentioned that it was a peak max, same as every stat in electronics (cepts for cpu's I suppose, but even those are underclocled usually).
Also, THE ONLY reason that blue dragon is on multiple disks is because of the HD CG cutscenes that Japs just have to have soooo badly. If they kept it all in engine for the cinematics you can bet it would be on one disc.

"At 2x Blu-ray can read as fast as 12x DVD's minimum read speed. At just
3x Blu-ray is comparable to DVD at 12x; through the first half of the
disc 3x Blu-ray is faster, through the second half of the disc 12x DVD
is faster.
And at only 4x Blu-ray manages to best a 12x DVD's maximum read speed
by 9%."
Also, Gears is only 6 gigs, so if it had some huge file it needed, then there is plenty of space to push sh*t to the outter edge/half of the disk...

All the xboys laugh at blu-ray, it cool. THe 360 uses dvd's. That would be like the PS2 using only cd's for games, that ***** would have been unacceptable. But M$ comes out with a "next-gen" console that uses last gen media, than laugh at Sony for creating new tech for their new console.
I guess Sony should have put out a half-ass console so 4 years latter they can come out with a real next-gen system. And hope to catch my competition in the middle of a console lifecycle. That's M$'s plan with the 360.

Of course it can be done this gen (see the end of my post for proof).
I told you this a few days ago in this thread and yet you didn't respond (despite the fact that you obviously read it);
http://ps3.qj.net/Funny-Ken-Kutaragi-Quotes-a-fan-boy-litmus-test/pg/49/aid/79353#comments
To quote myself "First, information can be arranged so that the data they want to be read the fastest is placed on the outside tracks. Secondly, if there's unused space, they can add dummy files to fill the inner tracks, hence pushing all the game data to the faster outer tracks.
Numerous games on both XBox and PS2 last gen used this technique to improve DVD performance. Hence those creating iso files for piracy purposes on the internet would often delete anything up to a GB of dummy files from the original game."
However, I also added the following;
"So to take the 360, if the devs used the last quarter of the DVD for the files they wanted to be read the fastest, the average transfer speed for those files will be 15.6Mb/sec!"
The day after I wrote this, I was made aware of the following link;
http://www.joystiq.com/2007/01/17/ps3s-blu-ray-drive-speed-could-be-reason-for-oblivion-delay/
"Overall, we know that the Xbox 360 drive reads data faster than PS3's. While the Blu-ray drive might consistently read data at the same speed, the 360 drive is FASTER at reading data on the OUTER layers of the DVD disc; AND THAT'S WHERE DEVS TEND TO PUT THE BIGGEST FILES."
So, you were saying? ;)
Regarding the points you raise again about the HDD, I've answered them in the link above, so I'm not going to repeat them again here.
