The PS3 version of CoD3 isn' t 1080p. The reason it looks better on 360, and the only reason, is that the engine was made for PC architecture. 360 is very much more lke a PC than PS3, ...PS3' s achitecture is exotic in comparison and it makes porting engines built for PC' s very difficult. You' d have to emulate some parts of the hardware, or completely re-write parts of the code to even get it running at all. On 360 it' s much easier, and then made even easier still because of XNA.
UE3.0 doesn' t like PS3, although i' m sure Epic will work something out, but even games like FEAR and CoD3 don' t look as good, even if there aren' t huge differences.
What PS3
needs is games built from the ground up, just for that platform. There you will see the better looking games but then you' ll only be able to compare them to gaes built from the ground up for 360, like say Gears of War and Mass Effect.
Either way, PS3 is capable of great things, just like 360 and direct comparisons of multi-platform games isn' t going to get you anywhere because some things, like VT3 which has been built for PS3
and 360 separately by different studios, will look better one way or the other. It' s daft to even think about it.
Motorstorm look waaaaay better than any 360 racing game, but Gears of War looks waaaaay better than every shooter/action game on PS3 that we' ve seen so far. Can the two be compared? No, obviously not, but you have one game on PS3 that looks better than any game of the same genre on 360, and you have a game on 360 that looks better than any game of the same genre on PS3.
When you go even further, you have Rainbow Six on 360 that will look better on 360, but you have a PS3 version that will probably look better than the 360 version of GRAW - one of the best looking games so far on the system...
Does it matter? Really? I dont think so.
Ninja Gaiden Sigma upon it' s release will be one of the nicest looking next gen games. On any system. Period. It' ll look better than most 360 stuff
and most PS3 stuff. Enough said.
