Am I the only playing on ps3, where after some time of playing, the game starts lagging like #%&@? I bought the game on ps3 so that it wouldn't lag, what the hell?!
But to be a little more serious, I would like to know if anybody knows if there is a fix or something. Would be really helpful.

ps3 version being the worst out of 3 platforms, you will have to wait for the patch.

Just quit the game back to XMB and start back up. It seems to get a little laggy if you play it for more than 4 hours with no restart. It was the same with Oblivion, FO3, FONV.
