In fact, they don't explicitly say that it involves the Xbox 360. Given the port job Capcom did on Lost Planet for PS3, it is entirely plausible that they had to duplicate too much data for the PS3 given it's Blu-Ray drive's slow read times.

Ultimately though, we know what this is. Hisiru pointed it out. They are just finding ways to make money. If they really made stuff THEN cut it they would offer it as free DLC. But they will actually have set out to have DLC from the beginning.

Certainly by all accounts it is inexpensive to have a game with two discs, Microsoft only charges substantial costs for three or more.

No, thats pretty much BS. Please try again.

yup. it is think about this

the xbox360's drive speed is a 12x CAV

the PS3's BLU-RAY DRIVE is also a 8X DVD CLV drive beside being also a 2x Blu-Ray drive

the xbox360 speed can only get to it's max speed  the very outer edge's of the DVD disc itself upto that point the speed

is no way near 12x it's arround 8x with dip's to 5x than that matter's what type of DVD it's reading a DL or single layer DVD.

while the Blu-ray drive is a constant speed  no matter where on the disc

a 2x Blu-Ray drive transfer's speed as fast as a 8x speed DVD drive

so how is it that the blu-ray drive's are slow reading drives again?

Ps3 = Blue ray 2x             9MB/s

X360 = Dvd 12x                16'2 MB/s

a 2x Blu-Ray drive transfer's speed as fast as a 8x speed DVD drive

no sir.

dvd 8x  10'8MB/s

correction:

you are thinking of it as a CLV which the xbox360's drive speed is not . like i said that the xbox360's transfer speed is  not constant..which in the PS3 it is.

where as the PS3's optical drive is: 9MB/sec CLV

the XBOX360 DRIVE data transfer is not at a constant transfer speed of 16MB/sec

and the average

8X DVD SPEED IF ITS A CAV IS 5.7 Which  IS 7.8 MB/sec and it only reaches that max speed if the disc is completely full, and if its on the outer most part of the disc. and this average reading speed is even slower if reading from DL-dvd's .

if you do not think so

look up the DRIVE SPEED's  this is  in scott mueller's upgrading an repairing pc's page 776-777

17th ed.

scott's textbook Its right on my shelf right now

When he is not working on PC-related books or teaching seminars, Scott can usually be found in the garage working on performance projects. This year a Harley Road King with a Twin-Cam 95ci Stage III engine continues as the main project (it's amazing how something with only two wheels can consume so much time and money ), along with a modified 5.7L '94 Impala SS and a 5.9L Grand Cherokee (hotrod SUV).

I have been using it for year's

 for example:

so let's take the 12x speed of the xbox360 optical drive

it can transfer 16,6 MB/sec the average speed is 8.5 the average transfer rate is 11.7 MB/sec  the max of 16 MB/sec is only seen on the outer most part of the disc.

and this is a optimistic average speed only if the entire disc is full.

if its not than it would be even slower. why do you think microsoft section's off part of the disc in the first place.

 

sorry dude but It can transfer faster or slower depending on where the developer places the data in the disc.

an I JUST POINTED that out did you not read what i just posted?

look the problem is the CAV drive is not a CLV drive which means that 16MB is optimistic value based on many thing's i just stated, and to be sure why do you think Microsoft section's off a part of the Disc!.

that's the point I am driving at the slower transfer speed between the xbox360's DVD drive and the Blu-Ray Drive in the PS3 is moot point. for the simple fact that on Average the Blu-Ray drive in the ps3 will perform just as fast as the xbox360 dvd drive in transfering Data .

only in certain area's will there be a slight speed advantage and that is pretty much slim due to the very fact that the

DVD drive have to read DL-dvd9's which will already slow their performance because if Microsoft did not section off part of that disc it would effect the speed even further.

since the DVD drive in the XBOX360 is a CAV not a CLV drive

why do you think the Blu-Ray drive in the PS3 is so expensive vs' the DVD drive in the xbox360

Blu-Ray is one part the other is the fact its a CLV optical drive. and it's also a 8X CLV DVD optical drive to boot.

Like I stated this is on Average, but the problem is on Average the xbox360's drive will dip in speed based on where their data is and the closer to the inner part of the disc the slower it is, that does not even take into account the laser having to go through multiple layer's. there is alway's going to be a hit in it's performance. to offset this Microsoft section's off part of the disc. but when have you seen the game's microsoft use that use up the full disc?

you do know the 16 MB's benchmark for a CAV dive is calculated for what the DRIVE's performance

is with SINGLE LAYER DVD's

the same drive reading a  DL-DVD's take a big hit in transfer of data

it's transfer rate is much lower than 16 MB/sec just look at it Average speed of 11 MB/sec it's Average speed drop's to 8.5x just on Single layer that's is Optimistic rate that may not even be that high. an rember that's just benchmarked for a single layer.

there is a reason why the xbox360's optical drive is cheaper than a TruX rated drive this is one of them.

to tell you the truth Microsoft would have been better off going with the HD DVD optical drive like the Blu-Ray Drive it was also a CLV optical drive
