Its stop gap when its just a 6800 thats not optomized for the CELL...

Colour me impressed, if that is true. Clock cell up to 3.2GHz, replace the stop-gap GPU with RSX, and give the developers time to properly optimize for the SPEs and for RSX, and the framerate should go up to 30-40 fps.
But, KZ really does look too good for me to believe that it was running at even 5fps on alpha kits.

So its not running in sli mode? And what do you mean when you say optimize for cell? The connections?BlueTsunami said:ralexand said:A dual 6800 isn't exactly a stop gap gpu.phat said:OpaOpa said:5 frames per second at 75% power. Let's try and digest that figure for a moment...

6800 SLI is extremely CPU limited and a 7800 is even more so. Chances are the demo was CPU bound. In that case performance would improve when the game is optimized for Cell.

It was running on a 2.4ghz Cell. What? They have that kind of rendering, but its not even in the least optimized for the hardware it is being rendered on?
6800 Sli and Cell at 2.4ghz (even if with only 4 Spes) is very very powerfull.

But Halo wasn't running on hardware that has significantly less performance than final, nor on a radically different architecture that people have had only a few months of experience on. Alpha to final PS3 should see a 1.5 to 2 times increase in performance, but the real gain will be in optimizing for the SPEs, would could easily add another factor of 3 to 4 to the game's performance.
But, again, I really doubt KZ was running 5fps on alpha kits...

Seriously doubt Killzone 2 CGI trailer was realtime even at 5fps, kinda sounds like some one got confused... but then again this entire situation has everyone confused right now. The bottom line is if Sony does not show something playable that looks as good as the CGI trailers they showed during the E3 they are going to be hearing a lot of harsh words from a lot of people.
Also... don't mistake a game being "CPU limited" as the amount of bandwidth between the CPU and the GPU, but rather the CPU has reach it's limit in regards to that game and the task the CPU is needed for in that game. With that said... the Cell CPU could very easily be MORE CPU limited than your standard P4/AMD64 in regards to certain games. I probably should do a test to prove this notion... so one of these days I am going to test a couple of games with my FSB cut by 3/4, memory clock cut by 3/4, AGP speed cut by 3/4... and probably a few other things to emulate certain differences. But if you think games today are CPU limited because of the amount of bandwidth available with PCIe or AGP or the fact that CPUs don't have very high floating point performance... think again.
Again for the last time... Killzone 2 was completely CGI and was not in any way realtime.

"in-game" is different from realtime... cut scenes are "in-game" but not realtime gameplay... there was no HUD so its not realtime gameplay. simple as that.
CoD2 is AFAIC close enough and realtime gameplay.
the question of the thread should be is... is KZ2 possible real time, in game? I say yes, others say no. We'll find out at E3 2006.
Now the real question is Killzone 2 (the Halo killer - LOL) gonna be better than Halo 3... the answer to that is clear also.. hells naw!
