@NewLynxS True, but NaughtyDog master Cell, so ps3 is getting better now :D

[NewLynxS]

@quangluu96 Did you read what I wrote? Yes, Cell can help with post-processing. But that requires additional programming on a different language, and that requires extra effort and money. Therefore, only exclusive developers invest on it, For multiplatform developers that is not good business, which is why most games end up better on the Xbox 360.

[quangluu96]

@NewLynxS the Xbox 360 is a bit faster than the PS3, but since Cell can help with graphic calculation, the PS3 can handle graphics better.

[NewLynxS]

@lLxJLxJl Again, the games don't run as well as on the Xbox 360 BECAUSE THE GPU IS SLOWER.

Also, again for the second time, Cell's core is the same as the Xbox 360's cores. Only the SPEs require specific code. Exclusive developers invest in programming for the SPEs, which can aid the GPU in post-processing tasks and get better visual results. For multiplatform developers, most of the times that doesn't make economical sense, so they don't bother with the SPEs and games run on the GPU alone.

@NewLynxS if they all ran natively like they run on xbox, why cant the games look better and or have higher fps than xbox? the reason is because devs dont know how to use the cell. and so since they dont know, they simply try to convert the code causing lots of use of the processor

[NewLynxS]

@lLxJLxJl Continued...

Also, people who developed for the Xbox 360 do not need to write "new code" for the PS3, since they both use the EXACT SAME PowerPC core on their processors. They only need to program specifically for the SPEs, and only if they want to.

Also, C++ language is always the same, regardless of what platform you're running it on.

And finally, games run at lower framerates on the PS3 because the GPU is slower, not because something is being emulated.

[NewLynxS]

@lLxJLxJl My point is, God of War 3 uses a post-processing filter, not something based on subpixel samples (2x, 4x, 8x).

And no, they are not. The PS3 doesn't have any emulation software besides for PS1 games. ALL PS3 games, no exception whatsoever, are assembled on the PS3 SDK, which creates them specifically for the PS3 (Cell) platform. Whether developers want to use Cell's SPEs is up to them, but all PS3 games run natively on Cell's PowerPC core (PPE).

@NewLynxS hold on hold on. 1st of all i never mentioned a specific method of AA, i just said AA. 2nd. yes basicly some multiplatform games are being emulated on ps3, because its not takig use of its cell. they use the cell to perform tasks easier insted of writing new code just for ps3, which will be hard to replicate to c++ on xbox or pc. this is why games run at a lower fps than on xbox.

[NewLynxS]

@lLxJLxJl Nonsense. There is no emulation on the PS3. Any game, regardless of being multiplatform or not, is programmed specifically to the PS3 platform on the PS3 SDK.

Also, God of War doesn't use 8x MSAA. In fact, it doesn't use MSAA at all. It uses MLAA (morphological anti-aliasing), a post-processing filter which detects and blurs polygon edges on a completed frame, a completely different method.

@mydayisnight the only reason ps3 cant add AA to mulitplatform games is because , most multiplatform games are basicly being emulated on ps3 because they dont take use of its hardware correctly, if u look at killzone 2 or 3 u cant easily see it has the best graphics in FPS for both consoles and it even adds a 2xAA, and even in god of war 3 it adds an 8xAA
