Hardknock said:PS3 is not far off, it's slated to launch in the Spring. MGS4 was created on the same dev kit that this game was. The point is that a developer with the same amount of time with both machines, was able to get far better results on Xbox 360.
there is no ps3 kits.Only evaluation boards.A significative semantical distinction.NucNavST3 said:IIRC a dev on these boards has stated that when it comes to Sony kits, their Alphas are not much different than their finals, more of a tweak than radically different hardware.
MechanizedDeath said:AC4 shown for the PS3 is still two months old. They showed the same trailer at TGS that they showed in July. No idea if the 360 trailer is realtime, but many of the buildings and other art assets look pulled straight from the PS3 trailer. I don't see why it would have to be prerendered. No confirmation for/against.
No official word on when RSX has taped out. No confirmation for/against.
Plenty of realtime PS3 stuff has been shown. Just take a quick look around the web.
PS3 alpha kits are significantly different if you go by Goto. 30% lower clock on Cell and RSX, and 1/7 the bandwidth between the two chips. Not sure if any actual devs here have supported the notion, but the argument has been that PS3 alphas are closer in power than 360 alphas. Not that it's a mere "tweak". How reliable that info is no one knows. PEACE.
You can work out exactly the time it takes for the tile copy with the info in Dave's article. It runs at peak bandwidth.
It's a combination of things and the costs are going to be very scene dependant. Even if you can run at 95% efficiency with say 2 tiles, that's still 5% you're loosing. It not really much of an issue if you plan for it at the start, but you have to bear in mind that the majority of launch titles are based on guesses and often incorrect assumptions, they are commonly optimised late when it's impractical to redesign renderers, and 5% can be the difference between 60fps and 30 if it comes down to the wire.
None of the early hardware supported tiling and I'd bet money that any dev targeting launch who can't time and test a feature is going to err on the side of caution.
How do PS3 devs simulate the split memory pools and get a feel for the latencies when they have 5GB/s compared to the full 35GB/s of FlexIO? Isn't PS3 a system built with the close interaction of Cell/RSX in mind? It's more than a tweak. PEACE.NucNavST3 said:I would consider clock speed differences tweaks, whereas, going from an Apple Power Mac w/ 9800s/x800 to xenon and xenos a significant difference, with the Sony Alpha you may not have the speed, but you have the hardware.
I guess what got me thinking about that was ERPs post in another thread talking about tiling on the xenos and that devs have not had anything comparable to work with until they got the xenos, to me that is a bigger difference than using 2.4GHz cell vs. 3.2GHz, even moreso considering when they (360 devs) received Finals and the impending launch date.
5 GB/s?? the real number AFAIK is 2MechanizedDeath said:How do PS3 devs simulate the split memory pools and get a feel for the latencies when they have 5GB/s compared to the full 35GB/s of FlexIO?

NucNavST3 said:Its cool our versions of "radically different" are, umm, different. At the end of the day, I don't give a damn, I just want my games in HD and jaggieless.
Acert93 said:STOP THE PAIN!
1. The game is not released.
2. The games are obviously in different stages of development.
3. We are not comparing the same scene/time of day, etc for a relative comparison
4. RSX is not complete and have yet to receive final PS3 beta kits
5. Devs are just hunkering down on the 360
6. Cross platform games are going to look about the same anyhow.
#6 is important. Devs of cross platform games are going to have performance goals that fit nicely into the envolope of each system.
For all those people, all 2 of them, who were not aware of the fact that PS3 and Xbox 360 multiplatform games would look basically the same here you go. Outside of that... what is the point of this thread?
Ps- Have a nice day
So, nAo, do you think you will have to recode "alot" once you receive finals?
