PS3 OS Resources.

[NeoTechni]

Searching the info a bit I have found the numbers "leaked"? many time ago about the amount of memory PS3 SO allocated with firmware 1.60. The degree of "realism" of this numbers is subject of discussion, but what google archive says is this:

Basic SO footprint firmware 1.60:
52 MB main memory
32 MB graphic memory

Additional resources:
- Standard PS3 message dialogs -> for free
- Standard on-screen keyboard -> 7 MB
- Remote play -> 8 MB (for use with PSP maybe?)
- Hard disc related functions (saving, loading...) -> 5 MB
- Online startup utility -> 8 MB
- Full support of friends list utility -> 24 MB, but in the date of writing a smaller module (20 MB) was expected.
- Video chat (up to 6 users) -> 26 MB
- Voice chat -> 8 MB
- In-game microphone configuration -> 8 MB
- Integrated web browser -> 40-90 MB, depending on page and tabs opened.

If we believe the other data "extracted" from the thread, the basic SO footprint would have been reduced from 52 to 24 MB, which seems quite an improvement, if the functionalities remain, or maybe have been increased.

The friends list is huge in size, though. The on-line features, in general, are quite overwhelming, but the fact is that Killzone 2 seems quite an achievement even with this constraints.

What do you think of this numbers? Seems too high in some cases. I would like to know if they´re real and, if it´s the case, how much have been improved.

i cant imagine ps3 ever using that much

psp used 5 mb and did most of that
8 mb for remote play but 2% for a simple buddy list, no way
saving and loading should be near free
none of those numbers make sense

I think the amount of memory the PS3 OS ate at launch would have given you a heart attack

also i admit the dev i spoke with is def. not as trustworthy as a sony employee

 

[NeoTechni]

also a 1080p framebuffer is 8mbytes
720p is 3 mbytes
id imagine the vram taken would be 2x the output res or lower if the game is upscaled plus space for like 50 cached xmb icons

i apologize for multiposting as im at work on a umpc without a keyboard

im curious though
someone said psps footprink shrunk
what is it at now

Possible footprint is reduced via Linux cutout?

I doubt this will benefit in any way since there are so many old models with the ability to run linux and some people DO run linux on their consoles therefore I doubt Sony will remove the feature from existing models. And if indeed is smaller for the PS3 slim because of the cut out I doubt Sony will want better game performance out of the PS3 Slim compared to the older models because of extra memory available.

It's not being removed (see Cell Performance forum), and the different consoles can't have different memory footprints. So this is no benefit to PS3Slim.

Exactly

I'm sure the Linux support takes up space in the flash RAM / on-disk firmware, but I wouldn't imagine it would take any memory during GameOS operations.

I'm sure the Linux support takes up space in the flash RAM...

Quite possibly, but it's the same firmware whatever machine you have, so it makes no odds.

50MB OS footprint now http://www.playstationuniversity.com/ps3-os-footprint-slashed-to-50mb-1798/

Did NXE increase the 360's footprint?

 

[grandmaster]

Surely increasing the 360's footprint runs the risk of making a whole bunch of games incompatible with the system?

I would think if any console OS increased their memory requirements, outside of anything pre-allocated, it would break many many programs...

Well, yes that is what I would have thought. Fine, just asking Sony is catching up with the footprint...slowly.

Good catch, GuestLV!

That's an awesome presentation! Answers a lot of questions / confirms a lot of suspicions. Thanks!

EDIT: thanks you too deep

Good catch, GuestLV!

It's almost as though no one actually clicked on the link that deepbrown provided a day earlier

Good catch? I posted it a day earlier. Sigh. I mean I bumped this whole thread for it...

BTW here's another fact - Drake's U2 model is 37k polygons, not the 85k somebody referenced. Chloe's is 45k. There.

 

[Shifty Geezer]

Sorry! Dunno how I missed that. Maybe because Guest's link was SCEE so more official? I think you need a better marketting strategy for future links!
