Double Agent is optimized for 360 architecture which is why it doesn't run as great on the ps3. It's like on a PC running Oblivion with an ATI or Nvidia card. The game will work with either card but each card will run the game differently in terms of framerate and image quality. Take Devil May Cry which was a PS exclusive until recently. More than likely it will run better on the ps3 than the 360. Everyone is quick to blame stuff on lazy developers but the truth is some games will play better on 360 and some will play better on ps3. This isnt the first or the last time this will happen this generation so people just need to accept it...

I allude to this to, not many ppl recall that the Cell is essentially 2 architectures on 1 chip! Basically a PC processor (x86 IBM POWERPC core "the PPE") backed by 8 SPE's for high floating point performance (same ALU processors found in GPU's) so essentially the Cell is a CPU/GPU hybrid (PPE/SPE) with most processing being STREAMED between the 7 SPE's such as game data while the PPE handles minor performance issues like networking, sound, disc reading, input/output devices!
If a game was dev'd to run a high amount of processing on an x86 core processor in "out of order" instruction sets then the PS3 would perform much slower as stated by IBM when they said the Cell is lacking in GEBERAL PROCESSING performance, something both the PC and 360 are better at handling!
I think with Oblivion Bethseda had way more time then Ubi to re-write the engine to work more on the SPE's and not the PPE!
Further more this brings me back to my bold statement (STREAMED),... Even though many believe all systems to be the same or equal they are in fact not b'cuz the PC and 360 are examples of PARALLELEprocessing! Example: Dual core or tri (PC & 360) multi thread ect, in either the PC or 360 there multi core/threaded games would essentially "draw" a scene with say the 1st core drawing the top 1/3rd, the 2nd core drawing the mid 2/3rds, and the third core drawing the bottom 3/3rdsof a picture to complete a scene (which is good for GP but slows perfrmance when games get more advanced)
In the PS3 (stream processing) 1 core would draw the actual picture, the 2nd core would draw the shading, and the 3rd core the coloring ect until the scene is finished! So even though the PS3, 360, and PC have multi cores that handle multi threads itz the way in which a multi port game is dev'd to be written to those cores/threads that will determine itz performance!
In all, this old form of dual core/thread processing is enefficient not cuz imma Sony fan but take this into consideration! SLI, when you get SLI in a PC each GFX card handles 50% of the scene on screen (that synchronized parallele processing) even though it smooths out framerates at high resolutions the actual performance increse of a 2nd card only adds like 15%-20% performance instead of a 50%-100%. While with th emore advanced stream processing the higher you push the limit the more the processors try to balance the load keeping higher framerate regardless of the increased instruction load (that PS3 duck video with the FPS barely dropping or the one with the fish)
So yeah itz gonna take effort and time for devs to figure out how to make the best of deving next gen but the PS3 without a doubt will carry on longer with less a performance hit when advanced coding begins to take off!Â
