Why Xbox One's eSRAM Feels Limited Despite Potential To Store 6GB of Tiled Textures Using DX 11.2

"There's been a lot of discussion about the Xbox One's 32 MB eSRAM and how it is a limiter to the console's overall performance. Although some developers such as Capybara Games deny any bottlenecks with the technology, there is still a feeling of it being limiting despite potentially being able to store up to 6 GB of tiled textures when used in conjunction with DirectX 11.2."

Oh gamingbolt, nice try! LOL

I'm dizzy

Ezz20131867d ago (Edited 1867d ago )

so that's why your comments never make any sense
because you are always "dizzy"

at last we know the real reason

bjmartynhak1867d ago

Lol, nice try really

Not a single mention on deferred rendering? Which is the preferred technique at the moment? The one that requires 64 MB of framebuffer?

mewhy321867d ago

sounds like more damage control to me. imo

Fit 6gb of data into 32mb, that's some fancy shit.

darthv721868d ago

It's a 32mb buffer that will get used by those who know how to use it properly. As of is still in the early stages of figuring out HOW to use it without compromising the finished product.

time people, it takes time to do things right. Even Mr. rogers knows that.

It's really not much different from the 360 except that it's now ESRAM rather than EDRAM and there is 3.2 times as much available. They should already know how to deal with it.

cyclindk1867d ago

Yeah sorry, in this instance it isn't some fancy new chip or processor or something that unlocks all kinds of potential, it's a "workaround" plain and simple and workarounds don't "level up" "unlock special abilities" or get bonus XP weekends.

Doesn't the xbox os take up 3gb's of ram though?

sooooo 5gb's of ram.

5gb's vs 7gb's

mhunterjr1867d ago

This discussion isn't about the RAM, is the eSRAM.

And what are you talking about 5gb's vs 7GB's? Are you comparing it to the ps4? If so, you should know the ps4 OS, also uses 3GBs of RAM... Not that any that matters, the most taxing PC games never reach 4GBs.

Ezz20131867d ago (Edited 1867d ago )

your comment on ps4 OS RAM is from a rumor not a fact though
it was proven wrong by ps4 dev's who are using 6GB for their games
also sony never confirmed that
but MS on the other hand did confirm using 5GB for games and 3GB for OS

mhunterjr1867d ago (Edited 1867d ago )

@Ezz2013 no, Sony has explained exactly how the RAM will work at launch. Developers need to use 6GB while in development because their games are not yet optimized. That's why dev units have 12GB OF RAM. If any SONY developer actually releases a game that requires 6GB of RAM, and it still doesn't look or perform as well as the most resource intensive PC games (which no console games do at the moment) then it's because they are poor coders (which I know they aren't)

Ezz20131867d ago (Edited 1867d ago )

you have a point about the use of RAM in development
in the future more games will demand more though

but still
sony NEVER confirmed that they are using 3GB for OS
that was just a rumor
and like i said Developers are using 6GB for their games
the fact that they are allowed to use 6GB in their games development
prove this rumor wrong
since it say developers only allowed to use 5GB for games

mhunterjr1867d ago (Edited 1867d ago )

@Ezz2013 after Sony's internal document leaked, they made an announcement that clarified some misconceptions about RAM allocation. By responding to the leak and clarifying statements made in it, they essentially confirmed its legitimacy, big companies don't comment on rumors. In it the noted that there is 1GB of memory labeled as 'flexible memory'.

The normal mode of official dev kits shows 4.5GB available. The large mode, which includes flexible memory, shows 5.25GB available, but the extra is reserved for application development.

Perhaps there will be system updates in the future that free up more RAM for game usage, but right now, 5 is about the max, and that is more tha enough for the games we'll see at launch and for some time after.

Tell me which dev is going to release a game that requires 6GB.

Ezz20131867d ago

i'm not disagreeing with you
5GB GDDR5 is already over kill for games
also indeed they did comment on it
but AGAIN still never Said 5.5GB for games and 3 or 2.5GB for OS

can you show an offical comment from sony saying that ?!

mhunterjr1867d ago (Edited 1867d ago )


Here's the official statement from Sony
"We would like to clear up a misunderstanding regarding our "direct" and "flexible" memory systems. The article states that "flexible" memory is borrowed from the OS, and must be returned when requested - that's not actually the case.

The actual true distinction is that:

"Direct Memory" is memory allocated under the traditional video game model, so the game controls all aspects of its allocation
"Flexible Memory" is memory managed by the PS4 OS on the game's behalf, and allows games to use some very nice FreeBSD virtual memory functionality. However this memory is 100 per cent the game's memory, and is never used by the OS, and as it is the game's memory it should be easy for every developer to use it.
We have no comment to make on the amount of memory reserved by the system or what it is used for."

While they declined to list the specifics of their RAM allocations. There is a reason they only chose to address a single topic of the initial information leak. The fact that they responded at all lends tons of credibility to the leak.

The idea that there are games in development that require 6GB of memory is also based on a rumor, but there is likely some truth to it. To quote that source

"WITH THIS SAID: There are games in development that are using 6 GB of RAM. I will not say any more about this.

I will say: the RAM situation on launch, will not reflect the RAM situation in two years, and not reflect the RAM situation at the end of the console's life cycle. "

It's possible for both situations to be true, but don't expect games that require 6GB to be released until AFTER a system update that changes RAM allocation. This is no different than what we've seen with 360/ps3. As of right now, the evidence point to a 5GB limit for the near future.

Ezz20131867d ago (Edited 1867d ago )

i agree with alot of what you are saying
but you are out of bubbles sadly
sony didn't say how much they using for games yet
what they did comment on though
is the way they are going to use the RAM

it would be great to keep talking about this if you like by PM

Yeah, only just NOW are there top of the line video cards rolling out with (minus the Titan, which is 1,000.00 USD by the way) 6 GB of GDDR5 dedicated video memory. LITERALLY 99.9 percent of all other cards are 4 gigs or less, high end is 3 GB 6 (being ultra, soon to be 8).

And the focused development environment of consoles allows all of this hardware, as we all know, to be pushed much farther than their PC counterparts.

I've got a 7950 3 gig in my PC and it is great, but I'd almost put any of the top tier PS3 games up to anything the PC can offer (at my 7950s level anyway). *Note my system is a bit limited by the i3 and average system memory though.
