Bethesda, I love you and your games with all my heart, but here's something I find strange: apparently Skyrim runs poorly on PS3 due to memory limitations, which is the same reason you're having trouble optimizing Dawnguard for PS3. Also every little object interaction in the world (chests and doors opened, object placement, people talked to, sound played...) relies heavily on the RAM, which the PS3 has very little. Then explain to me: why does the PS3 handle Oblivion better than the 360 version?

What do you mean? Oblivion runs fine on Xbox 360.

Oblivion runs better on Ps3 because 4J Studios did an excellent job with it (and because they had alot of time)
Skyrim runs poorly on Ps3, not because of 'memory limitations' it has 512MB of RAM, just like the 360, however it's split, 256MB dedicated video & 256MB system (can use up to 224MB's of system RAM as video RAM) also, ps3 has XDR ram, which is a bit faster & efficient than the 360's RAM.
Bethesda simply gave ps3 users a sloppy 360 port.

Oblivion on the PS3 runs so well because it was ported by the 4J studios. Unlike Bethesda these guys are real professionals. For all I heard Oblivion run and looks even better on the PS3 than it does on the Xbox but I don't know if that is true.

Murt and the others can explain much better why this game performs so bad. I just want to let you know that the PS3 could definitely run Skyrim as Oblivion proofs. This game performs so bad not because of limited memory but because Bethesda ported it poorly without any optimisations and decided to release it well knowing that it is unplayable. Everything they said about the "new engine" and "lots of attention" was a big pack of lies.

You see? It IS possible to create an open-world RPG experience on PS3 without running at a snail's pace! Surely with all the critical and commercial success Bethesda gets from their games, you would expect some TLC in their PS3 games.

It runs well on 360, but the PS3 runs better.

Cue shotgun cocking sound.
Just kidding! But still, I expected Bethesda to learn from the PS3 port of Oblivion.
