So do you think GT5 will fill a 25gb bluray, or dual-layered 50gb? or even less?

How much bluray space will GT5 take up? Is it really possible to dual layer a bluray disc to "50GB" like I've read on the internet?
Or will they at least fill 25GB (standard space) of a bluray?
Is 25GB enough for the 1000 car models, sounds and physics plus tracks?
I'm sure they can squeeze it into 25GB, but with all the cars available (1000?) I hope it's gonna be over 25GB. If this has been posted before then sorry, I just wanted to asked quickly.:)
 
Well I actually think more, since the GT case appears to have 3 disc slots...
 
Dual-layer 50Gb discs are routine for movie Blu-ray (if not the overwhelming standard by now; I can't remember the last 25Gb movie I bought), so this is likely for GT5. And why not?

I've read that 75Gb is technically possible for current disc production facilities and Blu-ray players, but cost and lack of need is deferring that capacity.
 
It could well take up more than 50GB. I certainly would'nt be surprised if it did.

I think we should prepare to laugh in the face of anyone who complains that GT5 didn't fit on one disc. It will be the first game to do so on blu-ray format 'i think'. (I don't know if theres any big pc games out there on blu-ray which i don't know about, or any PS3 games)
 
I personally i am expecting a large install of some kind i would not be suprised if PD do a GT PSP style here allowing users to optionally install data to the PS3.

if this is the case it's likely to be the car data i would assume as that is likely to be smaller than the actually data disc.

So in simple terms I am expecting to see a 50GB main Data Disc and a 25GB Car data disc
 
It'll most likely fill most of a 50 GB dual-layered Blu-ray disc. But it may be even larger. Perhaps we'll have an extra Install disc, a la Forza.
 
Every PS3 game now on fills whole disc so that load times are better. If that is not the case developers has not done all to ensure quick load times on PS3 system.
 
GT5 can't be less than 50gb.
3 disks collection must be collcetor's edition or journalist set.
 
I don't think its gonna fill up a 50 gb disc. MGS4 did it because of 8 hours of full hd cutscenes whereas gt5 will propably have 1 hour max. The physics don't take a lot of space nor do the sounds but the graphics take a lot. However, the tracks are repetitive so they don't have to take more space for a track. An example: The indianapolis track is x bytes and is located in the folder XYZ. When you want to race in that track in arcade,on-line and gt mode the ps3 loads the same file from the same folder. You don't need to create this track for arcade, do it again for on-line and again for gt mode. Thats what happens with the cars too

Now moving on to CPU. The 1 3.2Gh core of the Cell is able to give specific orders to the other 7 spe's(semi-processors). 1 spe can do the physics,another the sound etc. Let 1 spe for the graphics. This spe needs to load the track file, the cars files etc. For the track file it needs to do it only once because its a circuit so it won't need a lot of power. Thus, compressing the track textures is pretty much possible because they need to be decompressed only once(until the race ends and you choose another track). As you can see here racing games don't require a lot of computing power

However, the GPU can leave some vertex calculations to the cpu in order to leave the other pipellines for better frame rates and anti-aliasing. So the 1 spe handling the graphics(from the previews example) needs to handle the vertex calculations too so that the GPU can process other essential graphics processes. I hope I didn't confuse you

When it comes to graphics of 1080p(real 1080p not like prologue's) anti-aliasing is not much needed. However, the textures have to be very but very detailed if the resolution is 1080p. Its very complicated to estimate the amount of space the game will take but I personally think that 50gb are a lot for a racing game. It all depends on the resolution, the texture streaming((de)compression of textures), the videos that the disc will have(My prologue got from 2GB to 10GB because of GTTV) and the detail put in textures. To sum up, only the graphics and the videos can make this game take 50gb.

What was wrong with just paragraphing all of that cobra? :odd:

I think around 50GB just because of all the cars.

Off topic

MGS4 was actually only 34 or so gb (I say only) and 95% of cutscenes were played inengine,think of zooming and octo camo changes.

The physics don't take a lot of space

On topic

True,they got most of the engine in 200mb,And because GT is essentially all about physics it takes up little space,as it's all code.

nor do the sounds

Unless they use uncompressed 7.1,seeing as there is around a 1000 cars,it will add up.

but the graphics take a lot.

I can imagine 15-25gb on cars,10-15gb on tracks depending on how they determine location.

No matter the final size it will be a massive game.
 
I actually have NO idea, but I do tend to snicker @ M$ for choosing a petty DVD drive in their "next gen" console (-:

I think Kojima said it took 50 gb or so.
Even if it is 7.1 each car sound doesn't last long
25gb on cars means 25 mb per car. It sounds reasonable but many cars are the same like gt4's 3 paganis.
Are the tracks gonna be 20 or 70?
If they are 20 then 750mb the track. And thats a lot. But if they are 70 then its 220 mb the track and thats a lot too(many tracks are small)
 
I think that we already have a data that would let us make an raw estimation on the GT5 size.

There are 2 titles with graphics and sound that will rather for sure remind the one that we are going to see in GT5 - these titles being GT5P and GT5 TT

What I did was just a set of 2 equations with 2 unknowns.
First for data from GT5P second for data from GT5TT

X - size of a car
Y - size of track

67X+6Y=1870
2X+1Y=220

X=10MB
Y=200MB

I took the downloaded version of GT5P because it has no movies.
According to GTP guide spec II (released as downloadable ) had 67cars.
6 tracks because for example Suzuka and Suzuka east in my opinion are 1file (as London and London reverse are) - I'm not a programmer so please correct me if I'm wrong.

So GT5 having only 20 tracks and 1000cars will in my opinion have a size of

20x200+1000x10=4000+10000= 14GB

in case of 20 locations and 80 tracks with about 200 track combinations (like Suzuka and Suzuka east) it would be 20GB

Physics engine size is "distributed" between cars and tracks.

Without videos, presumably without some part of modes data (GT mode Arcade mode etc) and track editor.

Although it would be best to have Z - physics engine size and the information if it is in correlation with cars or tracks or both or none of them... (and the size of 2d part of GT5TT for third equation ;) ) (if correlation of physics size with cars=0 and with tracks=0 we wouldn't need 3rd equation we would only took away that p.size from both M sizes)

For example if physics engine has 70MB in both games and has no correlation with cars or tracks at all minimum size of GT5 gets up to 18,709090909GB and max goes up to 25,745454545 which may prove that:

a)these calculations are very much wrong
b)there are some other variables that have an influence on game size (presumably number of songs in demo and TT, many many other things I have no idea about, but - PD has, and I could bet they do that kind of predictions themselves so in overall topic is quite interesting and my post - just a waste of time mine and yours who are reading it :) )

All that above is "in my opinion" nothing else.

First of all your calculations are correct Second of all some tracks are big other are small, not full detail is in everycar, the graphics are better in GT5 etc etc.
You don't have all the data you think you have. Moving to your equation:
X is not number of cars its the size each one takes as well as Y and M is nothing

No, I'm not a MS fan, but their decision was made prior to BluRay being chosen as the new industry standard.

BluRay was actually still a long shot at the time.

Being a Sony technology, I can't help but wonder what a somewhat precarious position this puts MS in for the next, next gen console.

Hmm thank you but - did you mean that my calculations are incorrect or do you really think these are correct ?

And yes nomenclature for X Y is wrong and indeed M is unnecessary - I have been constantly updating my post but you people were faster to replay ;)
 
This is what your equation should look like
with x the space cars take
y the space tracks take
z the space physics take
m the space all the other elements in prologue take
μ the space all the other elements in gt tt take
you took for granted that m=μ=z1=z2=0 and x1=x2,y1=y2
Thats not true

Your equation is too simplified
You basicly have 8 unkowns 2 inequalities and 2 equations. You can't solve that

Nice equation :)

Being persnickety? shouldn't that be 2[X2] and everything >0 ? ;)
Now we only need 2 more equations and some details from PD...

Mine was just a very raw estimation your would be quite nice estimation with error only depending on size of example x,y,z,mi,x2,y2,mi2,m2

Thanks for taking me down a peg.

How is that mr maths?
