Okay, but is that RAM towards anything innovative (never played Killzone)... or is it just going towards super big but ultimately super pointless 20 million polygon set pieces, million polygon characters (apparently Naughty Dog is looking into doing this), and super realistic looking guns with state of the art rendering? Cuz' I'll take a 4KB RAM game (or whatever the SNES was) like Super Mario RPG over a 3GB RAM game that is just another by the numbers military shooter any day.

 

Edit:  Just read the OP again... yup, 3 GB in graphics.  So now our military shooters will look super realistic.

Good for you big boy.

Did my post offend you or something?



They can't be stopped...

So much for the idea that graphics will be the only improvement next gen.

And here is why I Like GG more than the other Sony studios

 

They're not being (like Naughty Dog) "PS4 is PERFECT, I FUCKING LOVE SONY! , TEH POWER OF THE CELL , IT JUST FLIPPIN DEVELOP'S ITSELF!" 

They used "Spinlocks" probably because PS3 had a weird CPU structure (one Big core ,  lots of Small sub cores)  Spinlocking doesn't take much CPU resources , but it bugs out a lot since its well "Small" so if it bugs out there is no failsafe and it just stops, however with "mutexe" they're Fast and big, but are CPU hoggers,

 

However... they are WRONG about "spinlocking is not nice for multicore" actually it is made for that, I am guessing they meant its not nice incase they fail since if one of the threads fail the others kind of fail too, and the bugs are "Where is my head?!" kind of stuff.

When was Naughty Dog ever like that?  Or am I taking that sentence wrong?  Not trying to start something, but I've never seen Naughty Dog talk like that.

Interesting slideshow. Definitely room for improvement as far as post process resolution, precision buffer and anti aliasing goes. Obviously it would be nice to have the higher frame rate but I doubt we'll get that unless the graphics are pared back ala COD style. Just hope they use high quality motion blur to make up for it.

they're the ones who started the whole "the power of the cell" thing, and they continued it with Uncharted 2, they stopped saying that with UC3.

they always said stuff like "Uncharted is using only (something) percent of the power of the PS3!" "PS3 is the best console to work on (like they worked on anything else)" "Sony is the best partner we ever had (like they had another partner)"

Do you know what you're talking about?

1. PS3's SPU/SPE are isolated from each other, the only time threads get blocked is if data streaming to SPE's local memory gets congested. 

2. Spinlock uses lots of cpu because it constantly loops to check when the resource is free. Mutex is just a counter that +1 when a resouce is taken and -1 when the resource is free. Spinlock = fast but cpu intensive. Mutex = slow but less cpu intensive.

3. Spinlock is not nice for multicore systems because congested cores potentially will never get the resouces and when they are racing against more idle cores. Thread scheduler issue of not balancing thread load evenly among the cores.

Ah, I can understand why they would say that about the cell, but I think it was more of PS fans who blew it out of proportion.   I've never seen them say the last two things though.  Oh well I guess.

So left 5 more month for them to catch up for further improvement on everything with the extra 4GB RAM by launch F.T.W.

3GB for just graphics is a lot, especially at 1080p. I wonder how much of that is padded out texture cach to avoid stutter and smooth out streaming, I would love to see a breakdown of how it is actually allocated. GG are doing some really nice things on the tech side for a launch title. 

Edit: fond it lol

You generally don't want MSAA these days though, HQ FXAA/MLAA would be a good thing anyways.

Because the MSAA uses more resourses... maybe they will use again with PS4 games.


yeah, I think it's fine to use it for 1st gen PS4 games, but they can use the RAM for other things later down the line to save resources since MSAA uses a lot of RAM and bandwidth depending on the engine without most people even noticing the difference, it'd be a really good and smart trade for future engines.
